摘要
根据通信网络规模的大小,提出了两个身份认证方案,一种是直接认证,一种是基于认证服务器的认证。方案的实施过程中采用一种动态方式,即合法通信者之间每次可动态获得一个新的认证密钥。所提方案易于实现,具有可证明安全性,安全性由量子不可克隆性和方案本身的动态特性保证。
Two quantum identity One is to authenticate directly, authentication schemes based on communication network scale are proposed. the other is to authenticate based on the Authentication Server （AS）. A characteristic in the proposal is that the authentication key can be obtained dynamically. The proposal can be realized easier. The security is guaranteed by the no-cloning theory and the dynamical features of the proposed scheme.
