Description

Pp file transmission method based on the synchronous destruction technology of quantum key
Technical field
The present invention relates to quantum communications fields, more particularly to a kind of based on the point-to-point of the synchronous destruction technology of quantum key Document transmission method.
Background technique
Quantum communications refer to a kind of novel communication mode that information transmitting is carried out using entangled quantum effect.Quantum communications It is the new interdisciplinary that recent two decades grow up, is quantum theory and the new research field that information theory combines.Classics are logical Letter is compared compared with optical quantum communication, and safety and high efficiency can not all mention in the same breath therewith.This technology becomes and measures in the world at present The research hotspot of muon physics and information science, China also emitted first quantum communications satellite in 2015, carried out quantum communications and ground Study carefully.Quantum communications have the characteristic that is perfectly safe not available for conventional communication mode, lead in information securities such as national security, finance There are great application value and prospect in domain.
Its characteristics are as follows:
1) key of quantum cryptography is truly random, even if stolen taker is intercepted and captured, is also unable to get correct key, therefore Information can not be cracked；
2) there are two particles of Entangled State in communicating pair hand respectively, the quantum state of one of particle becomes Change, in addition the quantum state of a side will change at once therewith, and according to quantum theory, macroscopical any observation and interference, all Quantum state can be changed at once, cause its collapsing, therefore stealer's information as obtained from interference has been destroyed, and non-native letter Breath.
3) the unknown quantum state efficiently, transmitted can be in Entangled State before being measured, i.e., represent multiple states simultaneously. With increasing for quantum, the rate journey exponential increase of data is transmitted.
Information networking epoch, information security and concealment are aobvious to be even more important, and data are not pocessed in the transmission, It is easy to be attacked, important information is stolen by attacker.Therefore various Encryption Algorithm also generate in succession, to prevent the file information It is trapped.It concealment, the scheme of various private communication channels can be suggested, come in transmission process in order to reach important information simultaneously Meet the concealment of information.Technique on Quantum Communication is significantly mentioned because its transmission principle determines to have compared to conventional communication mode safety It rises, is determined that quantum communications will become an emerging strategic commanding elevation of the Future Information communications industry by this feature, China exists It is in world lead level in the research of Technique on Quantum Communication, is few in number in China new and high technology R&D work field surpass One of the technology of more international development level, and just from the point of view of research and development situation in recent years, quantum communications are hopeful to realize in a short time Cross-cutting breakthrough, but because the problems such as technology, construction cost determines that China's quantum communications do not have large-scale promotion application still Condition.
Disposal password sheet (One-time Pad；It OTP) is one of cryptography Encryption Algorithm.It is with random key (key) composition plaintext, and only use primary.Theoretically, such password is unbreakable, and its safety is by a gram labor De Aier Wood Shannon (Claude Elwood Shannon) is proved.Although there is significant limitation, it is wide General is applied in the advanced encryption algorithms such as SHA-3.
Its characteristics are as follows:
1) to the text encrypted, that is, disposal password sheet, it is necessary to be without specific rule.
2) code book must be at least more isometric than encrypted file.
3) text (code book) to encrypt can only be with once, and when not using, the text to encrypt should will be sold It ruins, to prevent reusing.
It 4) can not be by Brute Force.
Summary of the invention
For the interaction of data between information age intranet and extranet, the transmission problem of documentation, how to take into account and use just Victory and Information Security become the problem that numerous users face, and it is synchronous based on quantum key that it is an object of the invention to provide one kind The pp file transmission method of destruction technology, this method by quantum communications and the disposal password sheet that can not be guessed solution by violence, Form the high safety communicating method of safety.
To achieve the above object, the pp file transmission side proposed by the present invention based on the synchronous destruction technology of quantum key Method, which comprises the steps of:

3) the first quantum key scramble module in quantum cryptography engineering module be used for according to original private file size to First quantum key controls the first quantum key memory module in hinge and sends acquisition size corresponding with original private file The request message of quantum key；
4) the first quantum key controls hinge and submits to from the truly random quantum key of the first quantum key memory module taking-up First quantum key scramble module；
5) the first quantum key scramble module generates pseudo random number password, with the received quantum key of password scramble institute, Length is constant after quantum key scramble, and result is submitted to quantum cryptography engineering by the first quantum key scramble module after the completion of encryption Module；
6) quantum cryptography engineering module encrypts original private file using the quantum key after scramble, and by password hide to In encrypted cryptograph files；
7) cryptograph files that encryption obtains are sent to recipient by the first quantum key control hinge；
8) cryptograph files are submitted to the in quantum decryption stage die block by the second quantum key control hinge of recipient Two quantum key scramble modules；
9) the second quantum key scramble module extracts the password in cryptograph files, and according to the size of cryptograph files to second Quantum key controls hinge application quantum key；
10) the second quantum key control hinge extracts quantum key from the second quantum key memory module and is committed to second Quantum key scramble module；
11) the second quantum key scramble module carries out scramble to quantum key using password, after the completion submits to result Quantum decrypts stage die block, and quantum decryption stage die block is decrypted cryptograph files to obtain original using the quantum key after scramble Beginning private file.
Further, the first quantum key memory module and the second quantum key memory module synchronizing process be such as in step 2) Under:
1) size of the first quantum key memory module and hashed value are sent to the second quantum key memory module；
2) it examines the first quantum key memory module and the second quantum key memory module whether identical, then examines if they are the same Pass through, a point situation is handled if different；
1. the first quantum key memory module and the second quantum key memory module are divided into M if hashed value difference1, M2……MnA submodule；
The hashed value of each submodule is examined, if MiThe hashed value of a submodule is different, then deletes the M of both sidesiHeight Module turns again to step 1) and repeats to detect；
2. if length of the length of length difference and the first quantum key memory module than the second quantum key memory module First quantum key memory module and the second quantum key memory module are then divided into M by more L1, M2……MnA submodule；
The hashed value of each submodule is examined, if MiThe hashed value difference of a submodule is then deleted the first quantum key and is deposited Store up the M of moduleiThe M of a submodule and later L and the second quantum key memory modulei1) a submodule, turns again to Carry out duplicate test；
