基于SM2算法的无证书多重签名及其在区块链交易中的应用
Certificateless Multi-Signature Based on SM2 Algorithm and Its Application in Blockchain Transaction
摘要
Abstract
Multi-signature is widely used in blockchain transaction schemes.Despite increasing demand for the localization of blockchain applications,research on multi-signature has not sufficiently focused on secure and efficient SM2 algorithms.Additionally,most existing solutions rely on the Public Key Infrastructure(PKI)system to implement certificate management,which poses efficiency and scalability issues.Therefore,this study proposes a certificateless multi-signature scheme based on the SM2 algorithm.First,in the SM2 key generation stage,a certificateless cryptographic mechanism is introduced to avoid expensive certificate management,and a key holding proof is designed to resist malicious key attacks.Second,by introducing a tree structure,an"online-offline"SM2 multi-signature algorithm is designed to achieve efficient and highly scalable signature generation.The scheme is proven to satisfy the Existential UnForgeability under Chosen Message Attacks(EUF-CMA)in a Random Oracle Model(ROM).Finally,the proposed solution is applied to the Hyperledger Fabric consortium chain to optimize the blockchain transaction process.Results of a performance analysis show that,compared with existing signature schemes,the proposed scheme is more effective in reducing computational and communication overhead while ensuring security.关键词
