| 摘 要： | 文中提出了一个基于门限思想的身份认证协议。该协议适用于开放式网络环境中有多个服务提供者和用户请求服务需要保密的情况，同时，它还能实现会话密钥交换功能。与Lee-chang协议【1】相比，我们提出的这个协议降低了通信量和计算量，并且能克服Lee-chang协议存在的两个安全缺陷。

| Abstract: | In this paper, a user identification scheme based on threshold idea is proposed. This scheme is valuable especially when applied to some applications in which the identity of user should be protected when he requests a service and there are many service providers in the distributed computer network. As compared with the Lee-chang scheme, this scheme not only reduces computational complexities and communication cost, but also overcomes the two security flaws in the Lee-chang scheme. |
