Description

A method of PGP verification is carried out to Email based on block chain technology
Technical field
The present invention relates to the data safety of information technology and protection technology fields, and in particular to one kind is based on block chain technology The method that PGP verification is carried out to Email.
Background technique
There are many shortcomings for business account book used at present.Their inefficiency, at high cost, opaque and easy hair Raw fraud and abuse.These problems are derived from centralization, third party system based on trust, such as financial institution, these concentrations Change, the account book system based on trust can bring bottleneck and obstacle to settlement of transactions.Lack the transparency, and is easy to occur rotten It loses and cheats, these will lead to dispute.The cost for solving dispute, trade reversals or offer transaction insurance is very high.These risks and Uncertainty, which results in, misses business opportunity.
Summary of the invention
Email is added in target block chain to overcome the above deficiencies, the invention provides a kind of, Encryption software series based on RSA public affairs spoon and private spoon encryption system, it is ensured that Email from be issued to be received it is entire The confidentiality of information, integrality and non repudiation based on block chain technology carry out PGP verification to Email in the process Method.
The present invention overcomes the technical solution used by its technical problem to be:
A method of PGP verification is carried out to Email based on block chain technology, comprising:
A) one authentication server Server is set on network, when a user UserA is to another user When UserB sends Email, user UserA sends to authentication server Server and requests, and indicates that data connect in request Receipts person is UserB；
B) authentication server Server records effective timing after receiving request, and generates one by Encryption Algorithm New UserID, while generating a pair of new symmetrical identity code is UserID_001 and UserID_002；
C) authentication server Server obtains the public key of user UserB, and authentication server Server utilizes use The public key of family UserB encrypts UserID and generates UserID_S；
D) UserID_S of identity code UserID_001 and generation are sent to use by authentication server Server Family UserA；
E) Email is generated electronics abstract Digest using HASH function by user UserA；
F) user UserA using the identity code UserID_001 that receives by Email and electronics make a summary Digest into Row encryption generates encryption file DE；
G) electronics abstract Digest is sent to authentication server Server, authentication server by user UserA Server retains electronics abstract Digest；
H) user UserA is sent to user UserB for file DE and received UserID_S is encrypted；
I) user UserB decrypts the UserID_S received with the private key of oneself, and decryption generates UserID, and will be after decryption UserID is sent to authentication server Server；
J) authentication server Server receives the UserID that sends of user UserB and records behavior, authentication clothes Symmetrical identity code UserID_002 is sent to user UserB by business device Server；
K) user UserB decrypts received encryption file DE, solution using the symmetrical identity code UserID_002 received Email and electronics abstract Digest are obtained after close；
L) user UserB by the electronics obtained after decryption abstract Digest and step g) in authentication server Server The electronics abstract Digest of retention is compared.
Further, Encryption Algorithm is SHA256 algorithm in step b).
The beneficial effects of the present invention are: by chain structure based on block chain technology, can not distort, intelligent contract, altogether The technologies such as knowledge mechanism, asymmetric encryption and data secure storage are realized in e-mail management and are passed to the safety of confidential data Defeated, data transmitting-receiving certifications, and set up using distributed accounting system and improve careful data protection system.By the way that body is arranged Part certificate server Server realizes independent authentication technology, it is using accurate time source, the safe machine of high-intensitive high standard System, to confirm that system processes data is in information system in the relative chronological order of existence and relevant operation sometime Time anti-repudiation provide infrastructure service；It is kept accounts using distribution and promotes Information Security, have digitlization, high reliability, height Real-time, high flexibility, high scalability and the simultaneous techniques of original creation distributed node processing system, it is multiple for numerous industries In miscellaneous changeable application demand, effectively antagonizes hacker attack and artificially distort.
Specific embodiment
The present invention will be further described below.
A method of PGP verification is carried out to Email based on block chain technology, comprising:
A) one authentication server Server is set on network, when a user UserA is to another user When UserB sends Email, user UserA sends to authentication server Server and requests, and indicates that data connect in request Receipts person is UserB；
B) authentication server Server records effective timing after receiving request, and generates one by Encryption Algorithm New UserID, while generating a pair of new symmetrical identity code is UserID_001 and UserID_002；
C) authentication server Server obtains the public key of user UserB, and authentication server Server utilizes use The public key of family UserB encrypts UserID and generates UserID_S；
D) UserID_S of identity code UserID_001 and generation are sent to use by authentication server Server Family UserA；
E) Email is generated electronics abstract Digest using HASH function by user UserA；
F) user UserA using the identity code UserID_001 that receives by Email and electronics make a summary Digest into Row encryption generates encryption file DE；
G) electronics abstract Digest is sent to authentication server Server, authentication server by user UserA Server retains electronics abstract Digest；
H) user UserA is sent to user UserB for file DE and received UserID_S is encrypted；
I) user UserB decrypts the UserID_S received with the private key of oneself, and decryption generates UserID, and will be after decryption UserID is sent to authentication server Server；
J) authentication server Server receives the UserID that sends of user UserB and records behavior, it is therefore an objective to guarantee User UserB is received and without denial, and symmetrical identity code UserID_002 is sent to use by authentication server Server Family UserB；
K) user UserB decrypts received encryption file DE, solution using the symmetrical identity code UserID_002 received Email and electronics abstract Digest are obtained after close；
L) user UserB by the electronics obtained after decryption abstract Digest and step g) in authentication server Server The electronics abstract Digest of retention is compared.If compare content be it is consistent, illustrate that Email is not tampered with.
By chain structure based on block chain technology, can not distort, intelligent contract, common recognition mechanism, asymmetric encryption and The technologies such as data safety storage are realized in e-mail management and are authenticated to the transmitting-receiving of the safe transmission of confidential data, data, and It is set up using distributed accounting system and improves careful data protection system.It is real by setting authentication server Server Independent authentication technology is showed, it is using accurate time source, the security mechanism of high-intensitive high standard, to confirm system processes data In the relative chronological order of existence and relevant operation sometime, basic clothes are provided for the time anti-repudiation in information system Business；It is kept accounts using distribution and promotes Information Security, have digitlization, high reliability, high real-time, high flexibility, high extension The distributed node processing system of property and the simultaneous techniques of original creation has in numerous industries application demand complicated and changeable Effect is fought hacker attack and is artificially distorted.
Further, Encryption Algorithm is SHA256 algorithm in step b).
