specific Embodiment approach

[0144] 1) The regulator first invokes the Setup algorithm to generate the public parameter pp;

[0145] 2) Each user calls the Genloginfo algorithm to generate their own registration information C loginfo , and sent to the regulator;

[0146] 3) The regulator calls the Verifyloginfo algorithm to verify the registration information of each user, and the h||CH corresponding to each user identity id Public, once the user finds out his h||CH id If it is made public, it means that you have registered successfully;

[0147] 4) After the user's registration is successful, if the data in the blockchain application needs to indirectly participate in the user's public information and identity proof must be provided, such as the output address in Bitcoin. At this time, each indirectly participating user will call the Genidproof algorithm in advance to generate the user's identity proof id And publicly, such that, A create Each user can directly obtain B when creating data other Cre...

Abstract

The invention discloses a data traceability method of a block chain. The method comprises the following steps: 1) a supervisory authority generates a public parameter pp; Each user generates its own registration information and sends it to the regulatory authority; 2) the regulatory authority verifies the registration information of the user and discloses it; 3) when the data in the block chain application needs to indirectly participate in the public information of the user and need to provide the identity certificate; Each user in the Acreate obtains the user identity certificate required bythe Bother for indirect participation in the creation of data; Each user in the Acreate creates his or her own identity certificate, and then generates datatrace= [{proofid} id (belongs to) I, databody] crytool and sends it to the node network; 4) the node network verifies the received user data and records it in the block; 5) the supervisory authority obtains the data from the block chain and decrypts the data to obtain the identity set corresponding to each data.

Description

technical field [0001] The present invention belongs to the technical field of information security, and relates to a traceable mechanism design scheme of blockchain, specifically using chameleon hash (chameleon hash), concise non-interactive zero-knowledge proof (zero-knowledge Succinct Non-interactive ARgument of Knowledge, zk- SNARK) and other technologies to track the privacy information of blockchain users, which can ensure the security and overall efficiency of protocol execution. Background technique [0002] In the 21st century, with the rapid development of Internet, cloud computing, big data, artificial intelligence and other technologies, the whole society is becoming more and more digital, networked and intelligent. The blockchain, which has attracted more and more attention from the industry and academia, can better meet the needs of today's social development due to its digitization, networking, intelligence, and data immutability. Today, blockchain technology...
