Description

ELECTRONIC CERTIFICATE DEVICE

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a device for producing, signing and recording an electronic certificate containing a plurality of mentions applicable to a batch of electronic documents and capable of being signed by a plurality of signatories, said device comprising a processing, a smart card, a smart card reader, a communication base intended to receive said smart card reader and capable of communicating, on the one hand, with said processing unit, and on the other hand, with a central database, said central database containing in particular the information relating to the potential signatories of the electronic certificates and all the information relating to the electronic certificates already signed and registered.

The invention also relates to a method for producing, signing and recording an electronic certificate containing a plurality of mentions applicable to a batch of electronic documents and capable of being signed by a plurality of signatories by means of said device.

STATE OF THE PRIOR ART

An electronic signature certifies that an identified person has approved the content of a specific electronic document. said signature is admissible in court as evidence. The burden of proof is reversed if this electronic signature is "presumed to be reliable", that is, it meets a number of regulations or standards relating to the security of information systems.

The process of producing an electronic signature involves the following steps:

the signatory acquires, from a trusted third party, a pair of digital keys making it possible to perform asymmetric encryption. It is a private key and unique, held exclusively by the signatory, used for encryption, and a public key, free access, for decryption; a unique fingerprint of the electronic document to be signed is generated by means of a hash function;

- the unique fingerprint of the electronic document is encrypted by the holder of the private key;

- The encrypted fingerprint is associated with the electronic document then the whole is transferred to the recipient.

The recipient decrypts the initial fingerprint of the electronic document using the public key that it holds, again generates, with the same hash function as initially, a fingerprint from the received electronic document and compares the fingerprint decrypted and the newly generated fingerprint. If both fingerprints are identical, the recipient has confirmation that the electronic document received is strictly the same as the electronic document sent and that this is the key private key corresponding to the public key it holds that was used by the person holding this private key to encrypt the initial print of the electronic document and implicitly approve said electronic document.

The recipient ensures the validity of the electronic signature by consulting a certificate indicating the identity of the organization that issued the keys, the characteristics of the person linked to the public key used (surname, first name, position in the company...) . This certificate may have been transmitted with the electronic document or obtained elsewhere.

Finally, the use of the public key to encrypt an electronic document makes it possible to make it confidential and to only target it to the holder of the private key.

The devices and processes of the prior art of producing an electronic signature do not make it possible to produce, sign and register an electronic certificate containing a plurality of mentions. For example, it is impossible to certify that an electronic document has been read, but not approved, has been drafted, but not approved. Thus, the notion of traceability, that is to say the possibility of attesting the different statuses that the same electronic document can take over time, can not be implemented. You can not, for example, certify that the electronic document was written by that person and then read by another person, then received by another person then approved by another person .... This list is not exhaustive.

In addition, these devices do not allow a plurality of signatories to produce, sign and successively register an electronic certificate for the same electronic document. For example, one person certifies that he or she has drafted a contract and then three others approve it in turn. Moreover, these devices do not produce, sign and register an electronic certificate for a batch of electronic documents. For example, a person certifies that he has issued and approved, in one operation, a batch of ten invoices.

Finally, these devices do not make it possible to create an electronic signature without modifying the electronic document itself since its encrypted footprint is associated with it. The object of the invention is a device and a method allowing a plurality of signatories to produce, sign and register an electronic certificate containing a plurality of mentions applicable to a batch of electronic documents (any computer file capable of be viewed or listened to) without affecting the said electronic documents and making it possible to consult all the information relating to the electronic certificates already signed and registered. Another object of the invention is to comply with the standards relating to the safety of information systems, in particular by ensuring the protection of electronic documents and related operations against alteration or falsification using methods other than encryption. For example, electronic signatures signed and registered can be recognized as evidence, with reversal of the burden of proof.

Another object of the invention is to allow verification of the information available on the signatories before their signature is definitively endorsed. Thus, it is freed from the management of certificates related to the validation a posteriori electronic signatures. Another object of the invention is to validate the identity of persons by comparing elements obtained during the signature with a reference located exclusively in a central database. Thus, the best guarantee is the inviolability of the signature.

Another object of the invention is to condition the decryption and provision of a decrypted electronic document to the signature and registration of an electronic certificate acknowledging this provision. Thus, the exclusive recipient of a confidential electronic document is obliged to acknowledge receipt so that he can read it.

DESCRIPTION OF THE INVENTION The aims of the invention are achieved by means of a device comprising a unit of processing, a smart card, a smart card reader having three communication areas and a memory divided into four storage compartments, a communication base for receiving said smart card reader able to communicate with said unit processing and with a central database.

This device also comprises three management modules. The first management module is implanted on the processing unit. The second management module and the third management module are located on the smart card reader. Said three management modules cooperate to perform a first group of operations when the smart card reader is positioned on the communication base and a second group of operations when the smart card reader is removed from the communication base. Said first group of operations makes it possible to constitute the batch of electronic documents to be processed, to check the content of the electronic documents to be covered by the electronic certificate and to record the signed electronic certificate. Said second group of operations makes it possible to secure the data characterizing the electronic documents to be covered by the electronic certificate, to consult the electronic certificates produced, signed and registered by previous signatories, to decipher the electronic documents to be covered by the electronic certificate, produce and sign the electronic certificate. The objects of the invention are also achieved by a method implemented by means of the device according to the invention.

The aims of the invention are finally achieved by means of software which constitutes the three management modules.

The processing unit houses the first management module which is dedicated to the operations of the method according to the invention which take place in said processing unit and to the communications between said processing unit and the smart card reader.

The smart card reader is a mobile element having a memory subdivided into four storage compartments. The first storage compartment is dedicated to the data exchanged between the processing unit and the smart card reader. Said first storage compartment communicates exclusively with either said smart card reader or with said processing unit.

The second storage compartment is dedicated to the data characterizing the electronic documents to be covered by the electronic certificate. Said second storage compartment communicates exclusively with the smart card reader.

The third storage compartment is dedicated to temporary work data. Said third storage compartment communicates exclusively with the smart card reader. The fourth storage compartment is dedicated to the electronic attestation data already transmitted or to be transmitted to the central database. Said fourth storage compartment communicates exclusively with the smart card reader.

Said smart card reader also has three communication zones that can be opened or closed by physical interruption, depending on the operation in progress.

The first communication area is dedicated to communications between the first storage compartment of the smart card reader and the processing unit. Said first communication area does not allow any other communication and can be opened or closed, by physical interruption, by the smart card reader exclusively.

The second communication area is dedicated to communications between the smart card reader and the central database. Said second communication zone does not allow any other communication and can be opened or closed, by physical interruption, by the smart card reader exclusively.

The third communication zone is dedicated to communications between the first storage compartment of the smart card reader and said smart card reader. Said third communication zone does not allow any other communication and can be opened or closed, by physical interruption, by the smart card reader exclusively. The smart card reader hosts the second management module which is dedicated to the operations of the method according to the invention which take place in said smart card reader. Said second management module permanently has exclusive and direct access to the second storage compartment, the third storage compartment and the fourth storage compartment of the smart card reader. Depending on the operation in progress, said second management module may also have access, via the third communication area, to the first storage compartment of the smart card reader. Said second management module also manages a status indicator continuously indicating what is the current operation in the process of producing, signing and recording an electronic certificate.

The smart card reader hosts the third management module. Said third management module permanently has direct access to the first storage compartment of the smart card reader. Said third management module does not access any other element of said smart card reader and is dedicated to communications with the processing unit.

The users of the device according to the invention are previously identified and each is provided with a smart card in which are stored personal data.

The communication base can receive the smart card reader and establish communication with it through the first communication area and the second communication area of said reader. smart cards. The communication base is further connected to the telephone network to establish the private network by which the smart card reader and the central database will communicate. The use of a private network makes it possible to better protect the operations carried out with said central database.

The central database contains information about potential signatories of electronic certificates. Said central database also contains other information necessary for the operation of the device according to the invention.

Finally, the device according to the invention comprises a website consisting of a partial and public replica of the central database and allowing in particular the consultation of information relating to electronic certificates already signed and recorded in the central database. The objects of the invention are also achieved by the method implemented by means of the device according to the invention. The method includes a first group of executable operations when the smart card reader is positioned on the communication base and a second group of executable operations when the smart card reader is removed from the communication base.

Said first group of operations makes it possible to constitute the batch of electronic documents to be processed, to check the contents of the electronic documents to be covered by the electronic certificate and to register the signed electronic certificate.

When the smart card reader is positioned on the communication base and the current operation is the constitution of the batch of electronic documents to be processed:

the second management module inactivates the control and reading tools of the smart card reader,

the first communication zone remains closed by physical interruption,

the second communication zone remains closed by physical interruption,

the third communication zone remains open,

the second management module records the ad hoc instructions in the first storage compartment,

the second management module closes the third communication zone by physical interruption. Thus, the data contained in the second, third and fourth storage compartments are inaccessible to the processing unit and are therefore protected against any modification or falsification that could come from said processing unit, - the second management module opens the first one. communication zone thus enabling the communication between the first storage compartment and the processing unit to be established,

the communication between the first storage compartment and the processing unit is established thanks to the first management module which regularly tests the possibility of accessing said first storage compartment and initiating the communication in collaboration with the third management module. Said communication can be secured by encryption and thus protect the current operation against any modification or falsification,

the instructions introduced in the first storage compartment are read by the first management module which makes said first storage compartment appear on the processing unit as a mass memory reader accessible for reading and writing.

When the smart card reader is positioned on the communication base and the current operation is the verification of the content of the electronic documents to be covered by the electronic certificate:

the second management module inactivates the control and reading tools of the smart card reader, the first communication zone remains closed by physical interruption,

the second communication zone remains closed by physical interruption,

the third communication zone remains open; the second management module records the ad hoc instructions in the first storage compartment;

the second management module closes the third communication zone by physical interruption. Thus, the data contained in the second, third and fourth storage compartments are inaccessible to the processing unit and are therefore protected against any modification or falsification that could come from said processing unit, - the second management module opens the first communication area thus allowing communication between the first storage compartment and the processing unit to establish itself,

the communication between the first storage compartment and the processing unit is established by means of the first management module which regularly tests the possibility of accessing said first storage compartment and initiates the communication in collaboration with the third management module. Said communication can be secured by encryption and thus protect the current operation against any modification or falsification,

the instructions introduced into the first storage compartment are read by the first management module which reserves said first storage compartment for its exclusive use.

When the smart card reader is positioned on the communication base and the current operation is the registration of the signed electronic certificate:

the first communication zone remains closed by physical interruption. Thus, the operations carried out with the central database are inaccessible to the processing unit and are therefore protected against any alteration or falsification that may arise from the said processing unit,

the second management module opens the second communication zone thus enabling the communication between the smart card reader and the central database to be established,

the third communication zone remains open,

- When the operations with the central database are completed, the device is automatically restored to the ad hoc configuration, depending on the result of said operations carried out with the central database.

Said second group of operations makes it possible to secure the data characterizing the electronic documents to be covered by the electronic certificate, to consult the electronic certificates produced, signed and registered by the previous signatories, to decipher the electronic documents to be covered by the electronic certificate, produce and sign the electronic certificate.

The operations of the second group of operations can only be performed on the instructions of the user when the smart card reader is removed from the communication base. Said operations are thus protected against any modification or falsification that could come from the processing unit.

When the smart card reader is removed from the communication base: the second management module closes the first communication zone by physical interruption. This is the default configuration for positioning on the communication base, - the second management module closes the second communication area by physical interruption. This is the default configuration for positioning on the communication base,

the second management module opens the third communication zone,

the second management module activates the control and reading tools of the smart card reader,

Thus, electronic documents present on the processing unit can be introduced by the signatory into the first storage compartment of the smart card reader when it is positioned on the communication base. A batch of electronic documents can thus be constituted. This characteristic therefore makes it possible to produce and sign an electronic certificate relating to a batch of electronic documents.

According to one embodiment, the introduction of electronic documents into the first storage compartment of the smart card reader is automated by using software installed on the processing unit.

As the batch of electronic documents is constituted, it can be moved, by the smart card reader, the first storage compartment (data exchanged between the processing unit and the smart card reader) to the third storage compartment (temporary work data) of said smart card reader. These electronic documents and the operations relating thereto will thus be protected from any modification or falsification by being physically separated from the processing unit and by being subject to security mechanisms specific to the smart card reader. This feature eliminates or complements encryption protection. This movement of the batch of electronic documents is possible only ordered by the signatory using the control tools of the smart card reader when it is not positioned on the communication base. No violation of the smart card reader from the processing unit is therefore possible during this operation.

The content of the electronic documents to be covered by the electronic attestation can be verified, by each successive signatory, using the first management module when the smart card reader is positioned on the communication base. The identical character of the verified electronic document and the electronic document that has been retained to be covered by the electronic certificate is checked by comparing the fingerprint, generated by the hash function, of the verified electronic document and the fingerprints, generated by the hash function, preserved and protected in the second storage compartment of the smart card reader (data characterizing the electronic documents to be covered by the certificate electronic). Several successive signatories can therefore ensure the content of the electronic documents to be covered by each electronic certificate and, by extension, obtain the guarantee that they produce and sign all electronic certificates relating to the same electronic documents.

The smart card reader allows each signatory to view the electronic certificates produced, signed and registered by the previous signatories, for the same batch of electronic documents. Each signatory can therefore produce and sign an electronic certificate for the same electronic documents with full knowledge of the facts. This consultation is only possible when the smart card reader is not positioned on the communication base. No violation of the smart card reader from the processing unit is therefore possible during this operation.

The choice of the mentions to be included in the electronic certificate and the request for decryption of the electronic documents can then be made using the smart card reader.

This operation is only possible when the smart card reader is not positioned on the communication base. No violation of the smart card reader from the processing unit is therefore possible during this operation. The list of information available for electronic certificates on the smart card reader is configurable. The content of the electronic certificates that can be signed is therefore not limited.

When the mentions to be included in the electronic certificate have been chosen and if a request for decryption of the electronic documents has been made, the signatory signs by identifying himself with the aid of the smart card reader. He presents his fingerprints to a module of the smart card reader dedicated for this purpose, introduces his smart card into the smart card reader and composes a personal code. This identification is only possible when the smart card reader is not positioned on the communication base. No violation of the smart card reader and the smart card introduced from the processing unit is therefore possible during this operation. When the identification of the signatory has been completed, the production of the signed electronic certificate and the possible decryption of the electronic documents are automatically performed by the smart card reader using the various data collected up to this stage of the process. . These operations are only possible when the smart card reader is not positioned on the communication base. No violation of the smart card reader from the processing unit is therefore possible during these operations. The electronic certificate does not contain the electronic documents concerned, but only their fingerprint, generated by hash function, and does not imply any modification of the original electronic documents.

When the electronic certificate is produced and signed, the identity of the signatory, validated in part with the aid of the smart card reader, must also be validated by the central database by positioning the smart card reader on the communication base. The signature of the electronic certificate is therefore not confirmed until the identity of the signatory has been the subject of the ad hoc verifications. This feature eliminates the management of certificates related to the validation, a posteriori, of electronic signatures.

Validation of the identity of the signatory is to ensure that the user of the smart card is the holder. For this purpose, the personal code of the signatory dialed from the smart card reader is compared to that which is written on the smart card and the fingerprints read from the smart card reader are compared with those entered in the smart card reader. the central database. Fingerprints never appear on the smart card, so they can not be obtained, even by violation of this card. This characteristic makes it possible to validate the identity of the signers by comparing elements obtained during the signature with a reference located exclusively in a central database. The inviolability of The signatory identification process is thus increased.

According to one embodiment, other verifications than those relating to the identity of the signatory are conducted. One can for example check the validity of the smart card over a given period, or the existence of a declaration of loss or theft of said smart card.

Once the identity of the signatory has been validated by the central database, the signed electronic certificate is automatically recorded. It is only after this registration that the signatory can recover any electronic documents decrypted within the chip card reader. This feature makes it possible to condition the decryption and provision of a decrypted electronic document to the signature and registration of an electronic certificate acknowledging this provision. Thus, the exclusive recipient of a confidential electronic document is obliged to acknowledge receipt so that he can read it.

The production, signature and registration of an electronic certificate for the same electronic documents can be implemented in a repetitive and indefinite manner. Several successive signatories may therefore produce, sign and register an electronic certificate for the same electronic document or batch of electronic documents. The process can be reset at any time to consider other electronic documents.

The information relating to the electronic certificates already signed and registered in the central database can be consulted on the website of the device.

The aims of the invention are finally achieved by software that constitutes the three management modules located on the processing unit and the smart card reader.

The software according to the invention comprises a first group of instructions for controlling the executable operations when the smart card reader is positioned on the communication base and a second group of instructions for controlling the executable operations when the card reader chip is removed from the communication base.

Said first group of operations makes it possible to constitute the batch of electronic documents to be processed, to check the content of the electronic documents to be covered by the electronic certificate and to record the signed electronic certificate.

Said second group of operations makes it possible to secure the data characterizing the electronic documents to be covered by the electronic certificate, to consult the electronic certificates produced, signed and registered by the previous signatories, to decipher the electronic documents to be covered by the certificate to produce and sign the electronic certificate.

In an alternative embodiment of the invention, the smart card reader 4 is integrated in a mobile phone. In this configuration, in addition to the possible pooling of a certain number of modules (screen, touch screen, alphanumeric keypad, etc.), said smart card reader 4 can communicate either with a computer, via the communication base 12, or with the rest of the mobile phone which then represents another type of processing unit 2.

Users of the device according to the invention are previously identified and each is provided with a smart card 3 in which are stored personal data. In the preferred embodiment of the invention, said data include the identity of the holder of the smart card 3, the personal code of the holder of the smart card 3, necessary for the use of said smart card 3, the unique identification code of the holder of the smart card 3, the private key of encryption attributed to the natural or legal person represented by the holder of the smart card 3 and the public encryption key of the exchanges with the database Central 13.

In a particular mode of use of the invention, the person represented by the holder of the smart card 3 may be said holder, but may also be a legal person. In the latter case, an electronic document may be intended for a legal person by being encrypted by the public encryption key of said legal person without the need to know a particular recipient individual. Within the entity that receives the encrypted electronic document, several natural persons representing the same legal entity, and therefore sharing the same private key encryption on their smart card 3, can decipher it. The communication base 12 can receive the smart card reader 4 and establish a communication with it through the first communication zone 5 and the second communication zone 7. Preferably, the connection of the communication base 12 to the unit treatment 2 is performed by a USB cable (Universal Serial Bus). However, the communication between the communication base 12 and the processing unit 2 can be achieved wirelessly via a Wi-Fi (Wireless Fidelity) link or a Bluetooth link without departing from the scope of the invention. The communication base 12 is further connected to the telephone network in order to establish the private network by means of which the smart card reader 4 and the central database 13 will communicate.

The central database 13 contains information relating to the potential signatories of the electronic certificates.

In the preferred embodiment of the invention, said information comprises the unique and perennial identifier of each smart card holder 3.
