In implementation, described method includes following steps:
Step S10 closes all remote access services that data provide the pre-selection underlying Operating System at end, and installs default
The remote access to application of type；
Wherein, the specific requirements condition of the credible performing environment based on cloud server preselects corresponding fundamental operation system
System.Cloud server is wide in range property concept, including all kinds of servers for belonging to cloud architecture, platform, system.It services beyond the clouds
It may include different credible performing environments on device；Corresponding, different credible performing environments has corresponding specific requirements condition,
It answers depending on the circumstances.For a certain credible performing environment, needs to pre-select and provide on end that run and meet can in data
Believe the underlying Operating System of performing environment specific requirements condition.Then step S10 is executed.Preferably, the remote access application
Program includes Jupyter application.Jupyter application program is a open source, the interactive of a variety of programming languages is supported to calculate ring
Connection and remote access between data offer end and Cloud Server may be implemented in border tool.
Step S20 makes the mirror image of the underlying Operating System；
The implementation for making the mirror image of underlying Operating System has been mature technology, and which is not described herein again.
Optionally, after making mirror image, further includes: the content for the mirror image that trimming has made, to delete the mirror
The service of the preselected types of picture.Understandably, the mirror image of underlying Operating System includes several different types of services.Here institute
Refer to that " service " is a broad concept, such as types of functionality code, application program, software.Mirror image is trimmed, is deleted useless
Service only retains infrastructure service relevant to data sharing, to construct the image file of lightweight, helps to reduce mirror image text
Part is uploaded to the time-consuming of Cloud Server, also helps the operational efficiency and stability for promoting data sharing.
Step S30 adds digital signature to the mirror image, and block chain is written in the digital signature；
In embodiment, the digital signature can be one group of abstract that image file is generated according to certain digest algorithm
Information (characteristic information), or the electronic signature obtained after being encrypted to the summary info.Specifically, it is calculated using public key encryption
The method that method signs to electronic information.For example, one group for being first depending on certain digest algorithm generation image file is plucked
It wants information (characteristic information), and the summary info is encrypted with the private key in generated public private key pair, form signature text
Part.
The digital signature of generation is directly appended in the default storage region of the mirror image, or as the one of the mirror image
Item attachment.
Distributed Storage, point-to-point transmission, common recognition machine on the digitized signature record of mirror image to block chain, that is, will be based on
The digital signature of mirror image is recorded (book keeping operation) by the block chain technology of the computer technologies such as system, Encryption Algorithm.Block is recorded
The digital signature of mirror image on chain is modified will to leave the modification trace (voucher) for being easy acquisition, therefore can be used for subsequent
Digital signature authentication, and then verify the validity mirror image of production (judge whether be tampered) of mirror image.
It should be noted that each step as described above is the series of steps of the mirror image production of basic operating system.It is all kinds of
The mirror image of underlying Operating System need to only make one.
Preferably, after step S30, comprising: the mirror image is uploaded to cloud storage region；
The image file for being added to digital signature is uploaded to the default storage region on Cloud Server, presets storage region
It can be dedicated for storing the mirror image warehouse of the image file of each mirror image.What image file was uploaded on Cloud Server default deposits
Storage area domain can be avoided image file and be stored in the home environment of data providing and illegally be distorted, only need using
Credible performing environment carries out just downloading the image file when data sharing, helps to improve the flexibility in use of image file.
Step S40, when receiving the enabled instruction of credible performing environment, found out from each mirror image made with can
Believe the mirror image of the corresponding underlying Operating System of performing environment as target mirror image；
When data, which need to obtain data using end, provides the related data at end, data log in Cloud Server using end, and
Data acquisition request is sent to Cloud Server and selects specific credible performing environment as the credible performing environment of target, thus
So that Cloud Server provides the enabled instruction that end sends credible performing environment to data.Data provide end according to the enabled instruction,
Confirm the credible performing environment of target (i.e. data use credible performing environment selected by end)；Based on credible performing environment, basis behaviour
The incidence relation for making system and corresponding mirror image, determines target mirror image corresponding with the credible performing environment of target.Such as determine target
The title of mirror image and version number.
Step S50 obtains digital signature corresponding with target mirror image from block chain and signs as check digit；
Specifically, the location information of digital signature corresponding with target mirror image is obtained, and according to the position of the digital signature
Set information extraction digital signature.
Step S60 judges whether the check digit signature is effective；If effectively, transferring target mirror image；
Specifically, a kind of to judge whether effective embodiment includes: the check digit signature
Step S61 obtains the digital signature for being added to target mirror image；
For example, from the digital signature file of cloud server downloading target mirror image.Alternatively, generating the digital signature of mirror image
Afterwards, which is stored to data and the local position at end is provided；The digital signature is extracted when executing step S71.
The digital signature of target mirror image is compared step S62 with check digit signature；
The unencryption if check digit is signed directly carries out the digital signature of target mirror image and check digit signature
It compares.If check digit signature is encrypted using public key encryption mode described above, the public key in public private key pair is used
Check digit signature is decrypted, then compares the check digit signature after the digital signature and decryption of target mirror image
It is right.
Step S63 determines that the target mirror image is effective if the two is consistent；Otherwise, it is determined that the target mirror image is invalid.
When the digital signature of target mirror image and consistent check digit signature, it was demonstrated that target mirror image is not tampered with, mesh
The safety of index glass picture determines that target mirror image is effective by verifying at this time；Otherwise, it is determined that check digit signature is invalid, directly tie
Shu Benci data sharing operations, and provide end using end or data to data and send the invalid prompt letter of digital signature verification
Breath, so that data user or data providing learn the information of authentication failed and make relevant counter-measure.
When determining that target mirror image is effective, if target mirror image is stored in advance in cloud storage region, Cloud Server is called,
And download the local storage region that target mirror image is stored in data offer end；If target mirror image is stored in advance in data and provides end
Local storage region then calls directly simultaneously operational objective mirror image.
Step S70 runs the mounted remote access to application, and with generating the remote access at data offer end
Location, and the remote access address is sent to data and uses end.
After the target mirror image downloaded from the mirror memory areas of Cloud Server passes through digital signature consistency checking, in data
The local boot target mirror image at end, namely starting target mirror image operating system are provided.Start and transport in the mirror image operation system
The mounted remote access to application of row.Such as starting Jupyter program；Based on Jupyter program, realize that data provide end
Connection and remote access between Cloud Server.It is and specific remote at this point, data provide end as a target access port
Journey access address is corresponding.The remote access address can be based on the generation of preset network communication protocol.
The remote access address of generation is sent to data and uses end.In turn, data user is carried out in data using end
Operation；Correspondingly, data connect Cloud Server using end, and input the remote access address, to be visited by cloud server
It asks that the data under target mirror image operating system provide end, and obtains corresponding local data, then pass via cloud server
It transports to data and uses end.In this way, data user, which realizes, provides the data acquisition of end side to data.
