Description
Claims (9)
- The method for secret protection 1. a kind of block chain is merchandised, it is characterised in that comprise the following steps:Transaction group is created between the node of block catenary system, user can create an account on block chain node, node generation account The transaction group is added after public private key information;Management node issues group public key and group's certificate for each node, and management node is held There is group private key;Transaction request node uses broadcast enciphering algorithm for encryption Transaction Information, and the broadcast enciphering algorithm specifies accounting nodes, pipe Reason node allows to check encrypted content;And group ranking is carried out to encrypted Transaction Information using group ranking algorithm so that hand over Easy information anonymous can be propagated;The Transaction Information after the broadcast enciphering and group ranking is broadcasted afterwards;Common non-accounting nodes after group's public key verifications using broadcasting Transaction Information;Accounting nodes are decrypted the Transaction Information and are performed Intelligent contract carries out book keeping operation processing, while intelligent contract preserves handling result, with transaction request node, accounting nodes and management The account public key of node charges to public account book after carrying out broadcast enciphering, and the data of preservation only allow accounting nodes, transaction request section Point and management node are opened.
- 2. the method as described in claim 1, it is characterised in that further include:Management node solves real account address using group's private key, and the group ranking of group user is tracked, and exposure signature Person's identity, to realize supervision.
- 3. method as claimed in claim 1 or 2, it is characterised in that transaction request node is signed using broadcast enciphering algorithm and group Name algorithm is traded information encryption and group ranking, processing further comprise:The transaction request node private key that accesses to your account signs whole Transaction Information;Transaction request node carries out broadcast enciphering using the account public key of transaction request node, all accounting nodes, management node;Group ranking is carried out to the Transaction Information ciphertext after broadcast enciphering.
- 4. method as claimed in claim 1 or 2, it is characterised in that common non-accounting nodes after group's public key verifications using broadcasting Transaction Information, further comprises:Common non-accounting nodes receive the Transaction Information, and the group ranking of the Transaction Information is tested using group's public key Card, if being proved to be successful, further broadcast, otherwise does discard processing.
- 5. method as claimed in claim 1 or 2, it is characterised in that accounting nodes decrypt the Transaction Information and perform intelligence Contract, which carries out book keeping operation processing, includes following operation:Use group's public key verifications group ranking;The Transaction Information ciphertext of broadcast enciphering, verification insider transaction signature are untied using the account private key of accounting nodes;Transaction request node account status is checked from built-in intelligence contract, if account is not present or abnormal state, is directly lost Fall transaction;Check intelligent contract state, if contract is deleted, directly lose transaction, return abnormal;Intelligent contract is performed, is modified according to transaction data, reuses transaction request node, accounting nodes and management node Renewal is into public account book after the encryption of account public key broadcasts.
- 6. method as claimed in claim 1 or 2, it is characterised in that further include:Accounting nodes are packaged into state after renewal and transaction block, and a block includes one or more Transaction Informations;Block is synchronized to adjacent node by accounting nodes;Common non-accounting nodes verify the block, preserve the block to local after being verified.
- 7. method as claimed in claim 6, it is characterised in that further include:Transaction request node carries out information inquiry by adjacent node;It is queried node and corresponding data is back to the transaction request node.
- 8. method as claimed in claim 1 or 2, user can create an account on block chain node, its node generation account is public Transaction group is added after private key information to further comprise:User creates an account on node;Node generates account public private key pair;The public private key file of node generation is simultaneously saved in local, and private key file is encrypted;Node initiates account creation application transaction, and recipient is built-in intelligence contract, carries mechanism ID and account public key, and intelligence is closed Account status is about preserved to be pending, key values are account public key;Intelligent contract examination & verification account is called by the management node for the group that merchandises The application of this group is added, or is directly carried out in next step;Group certificate is signed and issued to account according to group's private key, intelligent contract preserves account status and passes through for examination & verification, and preserves account public key Encrypted group's certificate.
- The intimacy protection system 9. a kind of block chain is merchandised, including multiple block chain nodes, it is characterised in that:Have in block catenary system There are one or more transaction groups, user can create an account on block chain node, add after node generation account public affairs private key information The group that enters to merchandise, which becomes group ranking, allows node, and the group ranking allows node to include:Transaction request node, common non-book keeping operation section Point, accounting nodes and management node, wherein:Transaction request node:For using broadcast enciphering algorithm for encryption Transaction Information, and using group ranking algorithm to encrypted Transaction Information is signed, and broadcasts the Transaction Information after the broadcast enciphering and group ranking afterwards;The broadcast enciphering algorithm is specified Accounting nodes, management node allow to check encrypted content;Accounting nodes:Book keeping operation processing, intelligent contract preservation processing are carried out for decrypting the Transaction Information and performing intelligent contract As a result while, charged to after carrying out broadcast enciphering with the account public key of transaction request node, accounting nodes and management node public Account book;Common non-accounting nodes:For using group's public key verifications and broadcasting Transaction Information;Management node:For solving real account address using group's private key, the group ranking of group user is tracked, and exposure Signatory's identity, to realize supervision.
