S45：The electronic equipment receives the message that succeeds in registration of management equipment, and obtains the block chain network according to described The block chain address of the identity information generation of electronic device user and one group of public key and private key.
In another embodiment, the identity identifying method may not include above-mentioned S41-S44 steps, above-mentioned user identity letter The directly artificial certification of breath is obtained by rear, the equipment logged in by certification personnel or electronic equipment transmission registration request Block chain address and one group of public key and private that the block chain network is generated according to the identity information of the electronic device user Key.
S46：The electronic equipment broadcasts the public key that the management equipment is obtained, and preserves the private key that the management equipment is obtained With block chain address.
For example, electronic equipment is after the message that succeeds in registration is received, related algorithm in self-operating block chain technology or Person generates block chain address by other nodes of block chain network for it, is used as the block chain address of the account of registration；And from Related algorithm in body operation block chain technology generates one group of public key and private key as the public key and private key of the account of registration.Tool Body, the block chain address can but not be limited to obtain, example subscriber identity information progress setting computing (setting Hash operation) Such as it is above-mentioned the whole network unique identity.The public key can be but not be limited to calculate block chain address progress set algorithm Arrive, or be directly the block chain address.The private key can be but not be limited to obtain public key progress set algorithm calculating.So Afterwards, electronic equipment is noted by the public key broadcasts in the block chain network so that the node 31 in network receives and preserves the user The account public key of volume.Also, its private key and block chain address are stored in locally by the electronic equipment, or the private key also can be transmitted Stored in the node trusty of setting, to back up.Now, Account Registration is completed.Wherein, the block chain node can lead to The block chain address lookup of any account in the network obtains the public key of the account, but private key then only logs in correspondence account Family node can just be obtained.
In a particular application, different according to the type of the login account, the purposes of public and private key is also different, for example, general The public and private key of logical account is respectively used to the encryption and decryption of account certificate processing record；The public and private key of Notified Body is used for Notified Body Digital signature verified；Checking the public and private key of structure is used for the encryption and decryption to checking information.
It is understood that above-mentioned database node 32 and management node 33 are the addressable node of node 31, but may not Block chain may not be participated in for block chain node, the i.e. node 32,33.Certainly, the node 32 and/or 33 can also be used as block chain link Point, for example can as block chain full node.In addition, the differentiation of above-mentioned node is according to true by the account of the Node registers Fixed, therefore same electronic equipment can be according to the different accounts of login as different nodes, and same electronic equipment is while conduct Multiple nodes, such as same electronic equipment is simultaneously as the database node 32 and the node 31a that issues licence.
The concrete mode that the block chain network is managed to electronic certificate is as described in example below.
Referring to Fig. 5, Fig. 5 is the schematic flow sheet of the embodiment of management method one of the application electronic certificate.The present embodiment In, this method is specifically included by the electronic equipment execution as above-mentioned block chain node 31：
S51：The process instruction processing electronic certificate that the response of first electronic equipment is received.
For example, the first electronic equipment receives what is inputted as the second electronic equipment of other block chain nodes or user The instructions such as request instruction, renewal request instruction or echo request instruction are made, the first electronic equipment carries out corresponding according to the instruction Operation such as makes electronic certificate, updates electronic certificate, recalls electronic certificate.
S52：The processing of electronic certificate record is encrypted first electronic equipment, and by the processing after the encryption Record is broadcasted in block chain network.
After the completion of handling electronic certificate, first electronic equipment obtains the processing record of the electronic certificate, the processing The process content for showing this is recorded, directly can typically be recorded the electronic certificate after processing as the processing.Then, Processing record is encrypted one electronic equipment, in the present embodiment, is encrypted using rivest, shamir, adelman.For example, should The block chain node that the follow-up block chain node for needing to feed back to request processing of processing record or user specify, therefore first electricity The account public key for the node that sub- equipment use need to feed back is encrypted, so as to receive the node of feedback according to itself account private key The processing record for obtaining unencryption is decrypted.
Each block chain node in block chain networking receives the record of the processing after the encryption or the only block The accounting nodes block chain node of power (can keep accounts) in chain network receive the record of the processing after the encryption, due to this plus The block chain node that the block chain node of the only above-mentioned request processing of close processing record or user specify, which can just be decrypted, to be obtained, Therefore other block chain nodes in network can not be decrypted and obtain original processing record, so as to ensure the confidentiality of processing record.On State can be after the block chain node encryption that receives current slot of reception processing record processing set of records ends be packaged in this In ground block as shown in Figure 2, and the book keeping operation for knowing together mechanism by common recognition mechanism such as Pow to compete the block is weighed.When the block Chain node obtains book keeping operation temporary, and the block is broadcasted to block chain network.Other block chain nodes of block chain network are to the block Validity verified, when the block chain network does not accept block validity, all block chain links of the block chain network Point abandons its block, and competition book keeping operation is weighed and generates new block as described above again；It is effective in block chain network approval block During property, the block or block head are synchronized on its block chain by all block chain nodes of the block chain network.Wherein, if The node is light weight node, then block head is synchronized with its current block chain, if the node is full node, by whole block It is synchronized with its current block chain.Now, that is, realize the processing record storage after the encryption in the block chain network In block chain.Record storage will handled after block chain, block chain node can be recorded using block-identified and alignment processing Cryptographic Hash search obtain correspondence block in store corresponding processing record, and then obtain electronic certificate information.
It is understood that when block chain network other block chain nodes as described in above-mentioned S51-S52 to electronic certificate When carrying out the processing record for handling simultaneously broadcast enciphering, first electronic equipment can also compete book keeping operation power as described in epimere, and will add Close processing record storage is in block chain.
S53：During the block for the processing record that the encryption for the electronic certificate that is stored with is generated in block chain network, the second electricity The block is synchronized to block chain by sub- equipment.
Wherein, the processing of the encryption is recorded as other nodes response request and handles shape to the electronic certificate Into, namely above-mentioned S5 is performed by above-mentioned first electronic equipment formed and broadcast in block chain network.As described in S52, when The node generation block of acquisition book keeping operation power in block chain network is simultaneously broadcasted after the block, and the second electronic equipment receives the block simultaneously By its synchronization in local block chain.
Asked for example, second electronic equipment is sent to above-mentioned first electronic equipment；Wherein, it is described to ask to be used for request pair Electronic certificate is handled.First electronic equipment is performed after above-mentioned S51-S52, the section of the acquisition book keeping operation power in block chain network Point generation stores the block of the encryption record of the electronic certificate and broadcasts the block.Second electronic equipment, which is received, to be remembered The block of the encryption record that is stored with of account power node broadcasts, and when block chain network approves the block validity, will The block is synchronized with local block chain.Certainly, if second electronic equipment obtains book keeping operation power, the second electronic equipment receives the The processing record of the encryption of the electronic certificate of one electronic equipment broadcast, and determine to record the encryption after obtaining book keeping operation power It is packaged in block, then broadcasts the block for the encryption record that is stored with, and approves that the block is effective in block chain network During property, the block is linked in local block chain.
S54：The processing record information of the encryption is decrypted second electronic equipment, the electronics after being decrypted The processing record of certificate.
For ensure the processing record reliability, the second electronic equipment be the encryption processing record be stored in institute The S54 is just performed after stating in the block chain of block chain network.For example, when the second electronic equipment is stored with the encryption in accreditation During the validity for the block for managing record, the processing record of the encryption is extracted from block, and block is synchronized in block chain, so The processing record of the encryption of extraction is decrypted using the account private key of itself afterwards, if successful decryption, it is determined that the processing Record is to feed back to itself, and obtains original processing record.
Further, to ensure the reliability of the processing, above-mentioned processing record is also using the numeral label of the first electronic equipment Name, i.e., be encrypted using the account private key of the first electronic equipment, for example, utilize the account private key of the first electronic equipment and second Processing record is encrypted for the account public key combination of electronic equipment, or is successively utilized respectively the account private of the first electronic equipment The account public key of key and the second electronic equipment carries out secondary encryption to processing record.Accordingly, the second electronic equipment utilizes first Processing record is decrypted for the account public key of electronic equipment and itself account private key combination, or is successively utilized respectively the first electricity The account public key of sub- equipment and the secondary decryption of itself account private key.If successful decryption, then it represents that processing record is to feed back to certainly Body, and digital signature of the processing record with the first electronic equipment account, handle what is obtained by the first electronic equipment account, Processing record is not tampered with.
