Anonymous revocation ring signature based on public chain and generation and revocation method of anonymous revocation ring signature

Abstract

The invention discloses an anonymous revocation ring signature based on a public chain and a generation and revocation method of the anonymous revocation ring signature, relating to the technical field of network security, the ring signature comprises a self-proving-based ring signature generation module and an anonymous identity cancellation module; the self-proving-based ring signature generation module comprises a key generation unit, a self-proving generation unit, a self-proving verification unit and a parallelizable ring signature generation unit, and the anonymous identity revocation module comprises a revocation initialization unit, a revocation initiation unit, a revocation judgment unit and a revocation effectiveness judgment unit. According to the invention, a ring signature parallel computing method based on cloud computing, an anonymous voting method based on ring signatures and a threshold password strategy are comprehensively used to realize efficient generation of ringsignatures of users on a public chain, conditional revocation of anonymous identities and security, fairness and credibility of a revocation process, so that the network security is improved.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to an anonymously revokable ring signature based on a public chain and a method for generating and revoking the ring signature, which is used to realize efficient generation of ring signatures for users on the public chain, conditional revocation of anonymous identities, and Ensure the security, fairness and credibility of the revocation process. Background technique [0002] Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is essentially a decentralized database. According to the classification of participants, blockchain can be divided into public chain, alliance chain and private chain. Among them, the public chain refers to a blockchain in which anyone in the world can read and send transactions and the transactions can be effectively co...

Problems solved by technology

[0008] The purpose of the present invention is to provide a method for generating an anonymously revocable ring signature based on a public chain in order to solve the problem that the anonymous identity of nodes in the existing public chain cannot be tracked, resulting in poor network security

At the same time, in order to solve the problem that it is impossible to adjudicate the anonymous identity of the nodes in the existing public chain and revoke the rebellious nodes, resulting in poor network security, a ring signature revocation method based on the public chain that can be anonymously revoked is provided.

In order to solve the problem of poor network security caused by the inability to track and adjudicate the anonymous identity of nodes in the existing public chain and revoke the rebellious nodes in the public chain at the same time, a ring signature based on the public chain that can be anonymously revoked is provided
