Transaction member needs just add the block chain being made up of each bank by authentication, in the present embodiment
Transaction member with block chain communicate by the front-end system in the transaction member carries out authentication.As shown in figure 3, Fig. 3
Being that the bank relevant with identity identifying method embodiment of the present invention is direct-connected clears block chain packet platform schematic diagram, the present embodiment body
The identity authorization system that identity authentication method is applied and an important difference of conventional authentication system are to be provided with Identity Management
System.In the block chain node of the multiple transaction member's compositions of each bank, the identity management system and the transaction member
It is connected with block chain node, the registration for the transaction member and log-on message transaction member issues block chain.Figure three
System shares the block chain node of 4 status equities, and block chain interstitial content does not limit to 4 in actual implementation, numerous nodes
Collectively form a network end to end.Each block chain node allows to obtain a complete data copy.Base between node
Whole block chain is safeguarded jointly by calculating jointly in a set of common recognition mechanism.Data exchange passes through digital signature technology between node
Verified.The public key of identity management system is configured in block chain node as configuration information, in communication process, the body
Part management system is communicated by the private key signature transaction of itself with block chain link point, and the block chain node can then use
The public key being pre-configured with is verified, so as to realize corresponding communication.It is flat that direct-connected clearance block chain packet platform also includes monitoring
Platform, monitor supervision platform are disclosed to read the Transaction Information in block chain, all friendships independently of identity management system
Easy information is shown, and is read to transaction member.In the identity identifying method step of the present invention, transaction member is needed to identity
Management system sends registration request, and the registration request includes the information that registration needs, only registered in identity management system
Transaction member could be communicated with block chain node.In the present embodiment, the transaction member refers to bank pre-machine, by institute
State bank pre-machine and send registration request.
Step S20, the identity management system are verified according to the registration request；
After the identity management system receives the registration request that the transaction member sends, entered according to the registration request
Row checking.Two kinds of situations can be divided into by sending the transaction member of registration request to transaction member in step slo：It is described transaction into
Member belongs to the transaction member for forming any one bank in the block chain and is not belonging to form any of described block chain
The transaction member of bank.The content for needing to verify can include：The information that the registration request that the transaction member sends includes is
It is no accurate；Whether the transaction member belongs to the transaction processing system of any bank in block chain.
The bank transaction processing system and the accurate registration request of information of transmission only belonged in block chain could lead to
Cross.
For example, some first block chain by and A, B and tri- banks of C and its subbranch form, only A, B and tri- banks of C
And its information of the registration request of the transaction processing system transmission of subbranch could accurately pass through checking.2 kinds of situations are obstructed below
Cross：
1) it is not belonging to the registration request that the transaction system of the composition bank of block chain is sent.
For example, bank D is not belonging to the first block chain as described above, bank D some front end processor 1 have sent registration request
1, but because D banks are not belonging to the member of block chain, the registration request 1 that front end processor 1 is sent, which is verified, not to be passed through.
2) the information inaccuracy that the registration request of the composition bank transmission of block chain includes is belonged to.
For example, bank A belongs to the first block chain, bank A front end processor 2 have sent registration request 2, but the note
The information content missing or information that volume request 2 includes are wrong, and the registration request 2 that front end processor 2 is sent, which is verified, not to be passed through.
Step S30, when the registration request is verified, the identity management system generates log-on message and is sent to
The block chain node, to cause the block chain node that the log-on message is write into block chain.
Identity management system has issues block chain node so as to obtain block hinged node write-in block chain the transaction of signature
Authority, and transaction member need in identity management system registration and by block chain node by log-on message write block chain after
It can just be communicated with block chain node.Identity management system itself randomly generates a pair of unsymmetrical key, the Identity Management system
Private key in the unsymmetrical key of system is used to signing Transaction Information, and the public key configuration in the unsymmetrical key of identity management system exists
Block chain node.When the identity management system carries out checking according to the registration request to be completed, the identity management system
A result can be obtained, the result can be transaction member's identity that third party provides according to identity management system
The result or identity management system that information is sent after being verified achieved according to itself by third party provide
The letter of identity of transaction member contrasts obtained the result with the identity information in transaction member's registration request.If test
It is by the way that the information that identity management system is then included according to registration request using the private key of itself to registration request is carried out to demonstrate,prove result
Encryption generation log-on message, the log-on message is sent to block chain node by identity management system, to cause wherein block chain
Node writes the log-on message in block chain, and transaction member is communicated with block chain link point.
For example, in the first block chain in step S20, the registration request 3 of bank A front end processor 3 is verified
Afterwards, the identity management system obtains the result being verified according to the registration request 3.Identity management system is according to
Log-on message corresponding to registration request 3 and registering result generation, and the log-on message is sent to block chain node, to cause
The block chain node writes the log-on message in block chain.
In the present embodiment, the transaction member sends registration request to the identity management system；The Identity Management
System is verified according to the registration request；When the registration request is verified, the identity management system generation note
Volume information is simultaneously sent to the block chain node, to cause the block chain node that the log-on message is write into block chain.It is logical
Aforesaid way is crossed, transaction member first sends registration request to identity management system, and then identity management system is to transaction member's body
Part is verified, is verified rear identity management system and signs transaction member's log-on message again and be sent to block chain node, with
So that Transaction Information is write block chain by block chain node.By setting identity management system to carry out registration pipe to transaction member
Reason, simplifies identity authorization system so that the transaction of the transaction member's signature registered in identity management system is sent to area
Block chain node, using the asymmetric close mark as identity of transaction member, is realized by checking and simplifies authentication procedures.
Further, based on the invention described above identity identifying method embodiment, reference picture 4, authentication of the present invention is proposed
The second embodiment of method.
In the present embodiment, the identity information of transaction member described in registration request described in step S20 and the transaction member
Corresponding first public key, described part management system carries out checking according to the registration request to be included：
S21, the identity management system send the identity information in the registration request to third party, to cause the 3rd
Side is verified by the identity information；
S22, the identity management system receive the result after the third party verifies to the identity information.
In the present embodiment, using identity of the unsymmetrical key as the transaction member, rivest, shamir, adelman
Need two keys：Public-key cryptography and private cipher key, are briefly referred to as public key and private key here.Public key and private key are a pair, such as
Data are encrypted with public key for fruit, and only private key corresponding to use could be decrypted；If data are encrypted with private key, then
Public key corresponding to only using could be decrypted.Because encryption and decryption use two different keys, this algorithm
Make rivest, shamir, adelman.Rivest, shamir, adelman realizes that the basic process that confidential information exchanges is：Party A generates a pair of secret keys
And disclosed using therein one as Public key to other sides；The Party B for obtaining the Public key is believed secret using the key
Breath is then forwarded to Party A after being encrypted；Party A solves private key to the information after encryption with oneself the another of preservation again
It is close.
Unsymmetrical key, particularly ECC keys, calculating speed is fast, cracks difficulty and increases up to index with key length
Rank, it is safe.If by the unsymmetrical key of some certain length and some is organized or individual security associations, by close
The identity of key is falsely used hardly possible in theory.According to the algorithm characteristic of unsymmetrical key, by differentiating some unsymmetrical key
Whether authentication algorithm is met, it can be determined that whether the individual and object for holding key obtain system registry mandate.
The unsymmetrical key of transaction member described in the present embodiment is randomly generated by transaction member, here it is described transaction into
The unsymmetrical key of member is referred to as the first unsymmetrical key, and the public key in the first unsymmetrical key is referred to as the first public key, corresponding private key
For the first private key.Transaction member's all identity informations and the transaction member couple when the transaction member that merchandises sends registration request
The the first public key binding answered is together.The identity information of the transaction member includes but is not limited to the affiliated bank's knot of the transaction member
The information such as structure title and transaction member's title in affiliated bank and coding.First private key is held alone by each transaction member
Have, for signing encrypted transaction message.Corresponding first public key bundlees in registration with identity information, in the Identity Management system
After system is registered and the log-on message is write into block chain by the block chain node, the block chain node can utilizes institute
State the public key of transaction member first transaction member is decrypted and verified using the transaction of the described first public and private key signature, from
And ensure the safety of Transaction Information.
, will wherein according to registration request after the identity authorization system receives the registration request that the transaction member sends
The identity information of transaction member is sent to third party.Third party can be in addition to identity authorization system and transaction member
Tripartite authority's authentication mechanism.
For example the front end processor 4 as belonging to the bank A in the first block chain of first embodiment is to described Identity Management system
System have sent registration request 4, and the information of the registration request 4 is accurate, including the identity information of the front end processor 4 and described preposition
The public key of machine 4.The identity information of front end processor 4 is issued the third party by the identity authorization system, and the third party is to described
The authentication of front end processor 4 by when, the result that the authentication of front end processor 4 passes through is issued identity management system.When not
The front end processor 1 for belonging to the bank D of the first block chain have sent registration request 1, described in the bank D is not belonging to
The first block chain, therefore authentication of the third party to the front end processor 1 be not by and the authentication of front end processor 1
The result not passed through issues identity management system.
Further, part management system carries out checking according to the registration request to include, Identity Management system
System is believed using the letter of identity of the transaction member provided in itself achieving by third party with the identity in transaction member's registration request
Breath is contrasted to obtain result.The counting personnel in the field should be appreciated that the result of two authentications listed herewith obtains
To mode simply play illustration, rather than restriction effect.
In the present embodiment, the of the identity information of the registration request including the transaction member and the transaction member
One public key, sufficiently includes authentication and subsequent transaction verifies required information.By the use of unsymmetrical key as transaction into
The identity of member, key length can ensure that caused key can not possibly collide.The individual and tissue for possessing key can confirm that.
In other words, key is unique sign of individual and tissue.In addition, asymmetric key algorithm is authentication center CA basic calculation
Method, almost possess the equal security mechanism of the digital certificates provided with CA.The identity management system is by the registration request
Identity information send to third party, to cause third party to verify the identity information, the then Identity Management system
System receives the result after the third party verifies to the identity information, is effectively guaranteed transaction member's body
The accuracy and reliability of part information.
Further, the identity identifying method embodiment based on the invention described above prompting, reference picture 5, proposes the present invention's
3rd embodiment.
In the present embodiment, after Transaction Information is write block chain by the block chain node, the friendship of the transaction member
Easy step is as follows：

Transaction member with block chain communicate by the front-end system in the transaction member carries out authentication.As shown in figure 3, Fig. 3
Being that the bank relevant with identity authorization system embodiment of the present invention is direct-connected clears block chain packet platform schematic diagram, the present embodiment body
The identity authorization system and an important difference of conventional authentication system that part Verification System is applied are to be provided with Identity Management
System.In the block chain node of the multiple transaction member's compositions of each bank, the identity management system and the transaction member
It is connected with block chain node, the registration for the transaction member and log-on message transaction member issues block chain.Fig. 3 systems
Altogether there is the block chain node of 4 status equities, block chain interstitial content does not limit to 4 in actual implementation, and numerous nodes are total to
It is same to form a network end to end.Each block chain node allows to obtain a complete data copy.It is based between node
A set of common recognition mechanism safeguards whole block chain jointly by calculating jointly.Data exchange is entered by digital signature technology between node
Row checking.The public key of identity management system is configured in block chain node as configuration information, in communication process, the identity
Management system is communicated by the private key signature transaction of itself with block chain link point, and the block chain node can then use pre-
The public key first configured is verified, so as to realize corresponding communication.Direct-connected clearance block chain packet platform also includes monitor supervision platform,
Monitor supervision platform is disclosed to read the Transaction Information in block chain, all transaction independently of identity management system
Information is shown, and is read to transaction member.When the identity authorization system of the present invention is performed, transaction member is needed to identity
Management system sends registration request, and the registration request includes the information that registration needs, only registered in identity management system
Transaction member could be communicated with block chain node.In the present embodiment, the transaction member refers to bank pre-machine, by institute
State bank pre-machine and send registration request.
Step S20, the identity management system are verified according to the registration request；
After the identity management system receives the registration request that the transaction member sends, entered according to the registration request
Row checking.Two kinds of situations can be divided into by sending the transaction member of registration request to transaction member in step slo：It is described transaction into
Member belongs to the transaction member for forming any one bank in the block chain and is not belonging to form any of described block chain
The transaction member of bank.The content for needing to verify can include：The information that the registration request that the transaction member sends includes is
It is no accurate；Whether the transaction member belongs to the transaction processing system of any bank in block chain.
The bank transaction processing system and the accurate registration request of information of transmission only belonged in block chain could lead to
Cross.
For example, some first block chain by and A, B and tri- banks of C and its subbranch form, only A, B and tri- banks of C
And its information of the registration request of the transaction processing system transmission of subbranch could accurately pass through checking.2 kinds of situations are obstructed below
Cross：
1) it is not belonging to the registration request that the transaction system of the composition bank of block chain is sent.
For example, bank D is not belonging to the first block chain as described above, bank D some front end processor 1 have sent registration request
1, but because D banks are not belonging to the member of block chain, the registration request 1 that front end processor 1 is sent, which is verified, not to be passed through.
2) the information inaccuracy that the registration request of the composition bank transmission of block chain includes is belonged to.
For example, bank A belongs to the first block chain, bank A front end processor 2 have sent registration request 2, but the note
The information content missing or information that volume request 2 includes are wrong, and the registration request 2 that front end processor 2 is sent, which is verified, not to be passed through.
Step S30, when the registration request is verified, the identity management system generates log-on message and is sent to
The block chain node, to cause the block chain node that the log-on message is write into block chain.
Identity management system has issues block chain node so as to obtain block hinged node write-in block chain the transaction of signature
Authority, and transaction member need in identity management system registration and by block chain node by log-on message write block chain after
It can just be communicated with block chain node.Identity management system itself randomly generates a pair of unsymmetrical key, the Identity Management system
Private key in the unsymmetrical key of system is used to signing Transaction Information, and the public key configuration in the unsymmetrical key of identity management system exists
Block chain node.When the identity management system carries out checking according to the registration request to be completed, the identity management system
A result can be obtained, the result can be that the transaction member that third party provides according to identity management system is carried out
The transaction member provided by third party that the result or identity management system sent after checking achieve according to itself
Letter of identity and transaction member's registration request in identity information contrast obtained the result.If the result is
By the way that then generation is encrypted to the information that registration request includes using the private key of itself according to registration request in identity management system
The log-on message is sent to block chain node by log-on message, identity management system, make it that wherein block chain node is by institute
State in log-on message write-in block chain, and transaction member is communicated with block chain link point.
For example, in the first block chain in step S20, the registration request 3 of bank A front end processor 3 is verified
Afterwards, the identity management system obtains the result being verified according to the registration request 3.Identity management system is according to
Log-on message corresponding to registration request 3 and registering result generation, and the log-on message is sent to block chain node, to cause
The block chain node writes the log-on message in block chain.
In the present embodiment, the transaction member sends registration request to the identity management system；The Identity Management
System is verified according to the registration request；When the registration request is verified, the identity management system generation note
Volume information is simultaneously sent to the block chain node, to cause the block chain node that the log-on message is write into block chain.It is logical
Aforesaid way is crossed, transaction member first sends registration request to identity management system, and then identity management system is to transaction member's body
Part is verified, is verified rear identity management system and signs transaction member's log-on message again and be sent to block chain node, with
So that Transaction Information is write block chain by block chain node.By setting identity management system to carry out registration pipe to transaction member
Reason, simplifies identity authorization system so that the transaction of the transaction member's signature registered in identity management system is sent to area
Block chain node, using the asymmetric close mark as identity of transaction member, is realized by checking and simplifies authentication procedures.
Further, with reference to figure 3, the second embodiment of identity authorization system of the present invention is proposed.
In the present embodiment, the authentication program is by block chain node, the transaction member and the identity
Management system can realize following steps when performing：
In the present embodiment, registration request described in step S20 includes the identity information of the transaction member and the transaction
First public key corresponding to member, described part management system carries out checking according to the registration request to be included：
S21, the identity management system send the identity information in the registration request to third party, to cause the 3rd
Side is verified by the identity information；
S22, the identity management system receive the result after the third party verifies to the identity information.
In the present embodiment, using identity of the unsymmetrical key as the transaction member, rivest, shamir, adelman
Need two keys：Public-key cryptography and private cipher key, are briefly referred to as public key and private key here.Public key and private key are a pair, such as
Data are encrypted with public key for fruit, and only private key corresponding to use could be decrypted；If data are encrypted with private key, then
Public key corresponding to only using could be decrypted.Because encryption and decryption use two different keys, this algorithm
Make rivest, shamir, adelman.Rivest, shamir, adelman realizes that the basic process that confidential information exchanges is：Party A generates a pair of secret keys
And disclosed using therein one as Public key to other sides；The Party B for obtaining the Public key is believed secret using the key
Breath is then forwarded to Party A after being encrypted；Party A solves private key to the information after encryption with oneself the another of preservation again
It is close.
Unsymmetrical key, particularly ECC keys, calculating speed is fast, cracks difficulty and increases up to index with key length
Rank, it is safe.If by the unsymmetrical key of some certain length and some is organized or individual security associations, by close
The identity of key is falsely used hardly possible in theory.According to the algorithm characteristic of unsymmetrical key, by differentiating some unsymmetrical key
Whether authentication algorithm is met, it can be determined that whether the individual and object for holding key obtain system registry mandate.
The unsymmetrical key of transaction member described in the present embodiment is randomly generated by transaction member, here it is described transaction into
The unsymmetrical key of member is referred to as the first unsymmetrical key, and the public key in the first unsymmetrical key is referred to as the first public key, corresponding private key
For the first private key.Transaction member's all identity informations and the transaction member couple when the transaction member that merchandises sends registration request
The the first public key binding answered is together.The identity information of the transaction member includes but is not limited to the affiliated bank's knot of the transaction member
The information such as structure title and transaction member's title in affiliated bank and coding.First private key is held alone by each transaction member
Have, for signing encrypted transaction message.Corresponding first public key bundlees in registration with identity information, in the Identity Management system
After system is registered and the log-on message is write into block chain by the block chain node, the block chain node can utilizes institute
The transaction that the public key of transaction member first signs the transaction member using first private key is stated to be decrypted and verify, so as to
Ensure the safety of Transaction Information.
, will wherein according to registration request after the identity authorization system receives the registration request that the transaction member sends
The identity information of transaction member is sent to third party.Third party can be in addition to identity authorization system and transaction member
Tripartite authority's authentication mechanism.
For example the front end processor 4 as belonging to the bank A in the first block chain of first embodiment is to described Identity Management system
System have sent registration request 4, and the information of the registration request 4 is accurate, including the identity information of the front end processor 4 and described preposition
The public key of machine 4.The identity information of front end processor 4 is issued the third party by the identity authorization system, and the third party is to described
The authentication of front end processor 4 by when, the result that the authentication of front end processor 4 passes through is issued identity management system.When not
The front end processor 1 for belonging to the bank D of the first block chain have sent registration request 1, described in the bank D is not belonging to
The first block chain, therefore authentication of the third party to the front end processor 1 be not by and the authentication of front end processor 1
The result not passed through issues identity management system.
Further, part management system carries out checking according to the registration request to include, Identity Management system
System is believed using the letter of identity of the transaction member provided in itself achieving by third party with the identity in transaction member's registration request
Breath is contrasted to obtain result.The counting personnel in the field should be appreciated that the result of two authentications listed herewith obtains
To mode simply play illustration, rather than restriction effect.
In the present embodiment, the of the identity information of the registration request including the transaction member and the transaction member
One public key, sufficiently includes authentication and subsequent transaction verifies required information.By the use of unsymmetrical key as transaction into
The identity of member, key length can ensure that caused key can not possibly collide.The individual and tissue for possessing key can confirm that.
In other words, key is unique sign of individual and tissue.In addition, asymmetric key algorithm is authentication center CA basic calculation
Method, almost possess the equal security mechanism of the digital certificates provided with CA.The identity management system is by the registration request
Identity information send to third party, to cause third party to verify the identity information, the then Identity Management system
System receives the result after the third party verifies to the identity information, is effectively guaranteed transaction member's body
The accuracy and reliability of part information.
