摘要/Abstract

摘要： 随着区块链技术发展以及广泛应用，链与链之间交互成为关注焦点，跨链身份认证与管理是实现区块链可信交互的基础。针对当前跨链身份认证与管理中存在的安全性与性能不足问题，提出一种基于ECC-ZKP的面向跨链系统的用户身份标识认证模型。通过研究跨链身份标识模型，引入椭圆曲线加密算法和零知识证明，实现跨链身份标识注册、更新以及认证，为用户的跨链访问、通信提供可信身份认证服务。分析与测试结果表明，该方案具有较高的安全性，且在处理效率、资源利用率方面表现较好。

Abstract: With the development and wide use of blockchain technology, the interconnection and interoperability between blockchains have become the focus of current research. Cross-chain identity authentication and management are the basis for trust interaction of blockchain. In order to solve the problems of security and performance in the current cross-chain identity authentication and management, a user identity and authentication model based on ECC-ZKP（elliptic curve cryptosystem-zero-knowledge proof） is proposed. By studying the cross-chain identity model, the elliptic curve encryption algorithm and zero-knowledge proof are introduced to realize the registration, update and authentication of cross-chain identity, and provide trusted identity authentication services for users’ cross-chain access and communication. The analysis and test show that the model has high security and good performance in processing efficiency and resource utilization.

Key words: cross-chain interaction, zero-knowledge proof, identification, elliptic curve encryption algorithm
