基于区块链的前向安全群签名方案
Blockchain-Based Forward Secure Group Signature Scheme
摘要
Abstract
Group signatures allow members to sign messages on behalf of a group,ensuring traceabil-ity.However,most current group signatures rely on a trusted third party,which have some issues such as single point of failure.Additionally,a trusted third party is often not feasible in reality.To address the issue in group signatures,this paper proposes a blockchain-based group signature algorithm,transferring the role of the trusted third party to smart contracts.Furthermore,a group manager proxy signature scheme is pre-sented,in which the original signature stored on the blockchain as a hash value for verification.Finally,the paper achieves forward security with a security time T =2k based on addition,and multiplication schemes.Security analysis and experimental results demonstrate that our scheme offers both security and efficiency.关键词
