摘 要
随着信息技术的迅猛发展，分布式网络环境下的跨域身份认证成为保障网络安全与用户隐私的关键问题。本研究聚焦于分布式网络环境中跨域身份认证机制的设计与实现，旨在解决不同信任域之间安全高效的身份验证难题。通过分析现有跨域认证协议的局限性，提出了一种基于区块链技术的新型跨域身份认证框架，该框架融合了零知识证明和智能合约机制，确保了身份信息的不可篡改性和隐私保护。实验结果表明，所提出的方案不仅能够有效降低认证延迟，提高系统吞吐量，而且在面对多种攻击场景时展现出更强的安全性。与传统方法相比，新框架实现了跨域认证过程的去中心化管理，避免了单点故障风险，同时支持多因素身份验证，增强了系统的灵活性和适应性。

Abstract
With the rapid development of information technology, cross-domain identity authentication in the distributed network environment has become a key issue to ensure network security and user privacy. This study focuses on the design and implementation of cross-domain identity authentication mechanism in a distributed network environment, aiming to solve the safe and efficient identity authentication problem between different trust domains. By analyzing the limitations of existing cross-domain authentication protocols, a new cross-domain identity authentication fr amework based on blockchain technology is proposed, which integrates zero-knowledge proof and smart contract mechanism to ensure the imtamability and privacy protection of identity information. The experimental results show that the proposed scheme can not only effectively reduce the authentication delay, improve the system throughput, but also show stronger security in the face of multiple attack scenarios. Compared with the traditional method, the new fr amework realizes the decentralized management of the cross-domain authentication process, avoids the risk of a single point of failure, and supports multi-factor authentication, which enhances the flexibility and adaptability of the system.
