Identity Ring SignCryption Based on Consortium Blockchain
-
摘要: 针对联盟链交易时存在的用户隐私泄露问题，该文提出基于联盟链的身份环签密(CB-IDRSC)方案。CB-IDRSC利用智能合约技术控制新交易加入，实现了公平可靠性；利用多个私钥生成器(PKGs)为用户生成私钥信息，满足联盟链部分去中心化要求和起到保护节点隐私的作用；并且具有机密性、不可伪造性和环签密者的无条件匿名性。性能分析中首先对CB-IDRSC中用到的智能合约进行部署；其次通过效率分析说明CB-IDRSC具有较高的计算效率；最后在忽略网络延时等因素影响的情况下，通过实验得出多私钥生成器的数量对系统参数生成和密钥生成阶段的效率影响不到3%。Abstract: Focusing on the problem of user privacy leakage during consortium blockchain transactions, IDentity Ring SignCryption based on Consortium Blockchain (CB-IDRSC) is devised in this paper. CB-IDRSC uses the smart contract technology to control the addition of new transactions, and so realizes its fairness and reliability; It uses the multiple Private Key Generators (PKGs) to generate the private key information for users, and so satisfies the requirements of partial decentralization of consortium blockchain and can protect the node privacy; In addition, it has the confidentiality, unforgeability and unconditional anonymity of ring signcryptors. In performance analysis, the smart contract used in CB-IDRSC is firstly deployed, and high computation efficiency of CB-IDRSC is shown by efficiency analysis. By ignoring the influence of network delay and other factors, the experiments show the influence of the number of PKGs to efficiency of setup phase with key generation phase is less than 3%.
