Abstract

The application of ring signature in blockchain can protect personal privacy anonymously, but the bad behavior records of malicious users cannot be tracked in practical use. In order to solve the problem of dishonest real signers, this paper modifies the ring signature algorithm, ensures the decentralized distributed application of the ring signature algorithm by adding some relevant information and key generation mechanism, and cooperatively tracks the identity of dishonest signers through polling and interaction with ring members at critical times, The generation and verification of algorithm signature are automatically completed by the blockchain smart contract code to realize the security characteristics of the system, such as transparency, anonymity, unforgeability and traceability. Through security analysis, the scheme is feasible and more efficient.
