PPP挑战握手认证协议(CHAP)，PPP【1】提供了点到点链路传输多协议数据报的标准方法。 在PPP中也定义了一种可扩展的LCP，允许协商认证协议，从而可以在进行网络层 协议传输之前对对端进行认证。 本文定义了一种PPP认证方法，该方法利用随机“挑战”和依据“挑战”和密钥 计算出的加密哈希“应答”来完成认证。 -PPP Challenge Handshake Authentication Protocol (CHAP), PPP [1] provides a point-to-point link multi-protocol data transmission of standard methods. In PPP also defines a scalable LCP to allow consultations authentication protocol, thereby conducting transmission network layer protocol before the end-to-end authentication. This paper defines a PPP authentication methods, The method using random "challenge" and the basis for "challenge" and calculated key encryption Hash "responsive" to complete certification.
