Passport Single Signon Protocol and Its Security Analysis

Abstract

Abstract: There are many frustrations for online consumers today,one of them is the repetitiveness of registering individually at each of their favorite sites .Each site often requires personal information and a unique name and password. Passport Single signon is a new online service which can help consumers only to use one username and one password to gain many service,what we will discuss in this paper is the theory of the protocol and its security analysis.

摘要： 网上购物时消费者会遇到诸多障碍，其中之一是必须记住多个不同的用户名和口令，并需重复输入个人信息，从而在多个不同的站点购物。本文介绍的Ｐａｓｓｐｏｒｔ单一登录协议可使消费者只需要记住一个用户名和口令就可以获得多个服务的认证。文章首先介绍Ｐａｓｓｐｏｒｔ单一登录协议原理，然后简要分析其安全特性。
