摘　　要：随着网络技术的不断发展,网络空间中不同体系结构、不同应用领域的身份管理系统协同并存,如何管理繁多的网络身份是一个具有挑战性的问题。本文总结了传统身份管理系统的特点,认为传统的系统大多依赖于可信第三方,将身份数据库集中存储在权威的中心机构,如果中心机构被入侵,所有用户的隐私就会被破坏。而且随着网络用户数量的激增,管理身份数据库所耗费的资源也在不断攀升。区块链作为一个新兴技术,其天然的去中心结构为身份管理提供了新的解决思路,本文总结了一些结合区块链技术的身份管理系统的特点,并对未来网络空间身份管理系统的发展提出了展望。With the development of network technology,identity management systems with different architectures and different application domains coexist in the network space.How to manage a large number of cyberspace identities is a challenging problem.This article summarizes the characteristics of traditional identity management systems,such as Microsoft's Passport project、IBM's Tivoli Access Manager,etc.Traditional systems mostly rely on trusted third parties to store identities.If the central organization is compromised,all users'privacy will be destroyed.Moreover,as the number of network users increases,the resources consumed to manage identity databases are also rising rapidly.As an emerging technology,blockchain's decentralized structure provides a new solution for identity management system.This paper summarizes the characteristics of some identity management systems that employ blockchain technology,such as Blockstack、CertCoin,etc.Then,presents a prospect of the development of cyberspace identity management system.
