| 摘 要： | 信息技术的快速发展使身份认证机制的安全性得到越来越广泛的关注.但现有的身份认证机制存在着隐私泄露等风险，这就要求设计出更加可靠的身份认证机制.本文利用区块链的去中心化、不可篡改等特性，设计出基于区块链的多方协作安全身份认证机制.在实现可靠身份认证的同时，保证信息的权威性，在一定程度上减少数据冗余，并提高身份认证效率，保证全面且准确的身份认证.最后实现支持多个数据服务商对身份信息进行加密签名，保护数据隐私，以及多方共享数据的身份认证系统.

| Abstract: | With the rapid development of information technology,the security of authentication mechanism has received more and more extensive attention.However,the existing identity authentication mechanism has the risk of privacy threat.Thus,designing a more reliable authentication mechanism is in urgent need.This paper designed a multi-party collaborative security authentication mechanism based on the blockchain for its decentralized and tamper-proof features.While achieving reliable identity authentication,it ensures the authority of information,reduces data redundancy,improves the authentication efficiency,and realizes comprehensive and accurate authentication.Finally,the authentication system is implemented,which enables multiple data service providers to encrypt and sign identity information,protect data privacy,and share data with multiple parties. |
