Description

A method of PGP verifications are 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 being based on block chain technology The method that PGP verifications are carried out to Email.
Background technology
There are many shortcomings for business account book used at present.Their inefficiency, of 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 can lead to controversy.The cost for solving dispute, trade reversals or offer transaction insurance is very high.These risks and Uncertainty, which results in, misses business opportunity.
Invention content
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 verifications to Email in the process Method.
Technical solution is used by the present invention overcomes its technical problem：
A method of PGP verifications are carried out to Email based on block chain technology, including：
A) one authentication server Server is set on network, when a user UserA is sent out to another user UserB When sending Email, user UserA sends request to authentication server Server, indicates that data recipient is in request UserB；
B) authentication server Server records effective sequential after receiving request, and by Encryption Algorithm generate one it is new UserID, while it is UserID_001 and UserID_002 to generate a pair of new symmetrical identity code；
C) authentication server Server obtains the public key of user UserB, and authentication server Server utilizes user The public key of UserB encrypts UserID and generates UserID_S；
D) UserID_S of identity code UserID_001 and generation are sent to user by authentication server Server UserA；
E) Email is generated electronics abstract Digest by user UserA using HASH functions；
F) user UserA is added Email and electronics abstract Digest using the identity code UserID_001 received It is close, generate encryption file DE；
G) electronics abstract Digest is sent to authentication server Server, authentication server by user UserA Server retains electronics abstract Digest；
H) UserID_S for encrypting file DE and reception is sent to user UserB by user UserA；
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 send of user UserB and records behavior, authentication server Symmetrical identity code UserID_002 is sent to user UserB by Server；
K) the encryption file DE that user UserB is received using the symmetrical identity code UserID_002 decryption received, after decryption Obtain Email and electronics abstract Digest；
L) user UserB makes a summary the electronics that server is retained in the electronics obtained after decryption abstract Digest and step g) Digest is compared.
Further, Encryption Algorithm is SHA256 algorithms in step b).
The beneficial effects of the invention are as follows：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 realize the safety in e-mail management to confidential data and pass Defeated, data transmitting-receiving certifications, and set up perfect careful data protection system using distributed accounting 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 intensity 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 The distributed node processing system of real-time, high flexibility, high scalability and the simultaneous techniques of original creation, it is multiple for numerous industries In miscellaneous changeable application demand, effectively antagonizes hacker attack and artificially distort.
Specific implementation mode
The present invention will be further described below.
A method of PGP verifications are carried out to Email based on block chain technology, including：
A) one authentication server Server is set on network, when a user UserA is sent out to another user UserB When sending Email, user UserA sends request to authentication server Server, indicates that data recipient is in request UserB；
B) authentication server Server records effective sequential after receiving request, and by Encryption Algorithm generate one it is new UserID, while it is UserID_001 and UserID_002 to generate a pair of new symmetrical identity code；
C) authentication server Server obtains the public key of user UserB, and authentication server Server utilizes user The public key of UserB encrypts UserID and generates UserID_S；
D) UserID_S of identity code UserID_001 and generation are sent to user by authentication server Server UserA；
E) Email is generated electronics abstract Digest by user UserA using HASH functions；
F) user UserA is added Email and electronics abstract Digest using the identity code UserID_001 received It is close, generate encryption file DE；
G) electronics abstract Digest is sent to authentication server Server, authentication server by user UserA Server retains electronics abstract Digest；
H) UserID_S for encrypting file DE and reception is sent to user UserB by user UserA；
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 send of user UserB and records behavior, it is therefore an objective to ensure user UserB is received and without denial, and symmetrical identity code UserID_002 is sent to user by authentication server Server UserB；
K) the encryption file DE that user UserB is received using the symmetrical identity code UserID_002 decryption received, after decryption Obtain Email and electronics abstract Digest；
L) user UserB makes a summary the electronics that server is retained in the electronics obtained after decryption abstract Digest and step g) Digest is compared.If it is consistent to compare content, 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, realize the transmitting-receiving certification of the safe transmission, data in e-mail management to confidential data, and Perfect careful data protection system is set up using distributed accounting system.It is real by the way that authentication server Server is arranged Independent authentication technology is showed, it is using accurate time source, the security mechanism of high intensity 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 algorithms in step b).
