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.

树是由n(n≥0)个结点组成的有限集合T。n=0的树称为空树；对n>0的树，有:(1)仅有一个特殊的结点称为根结点，根结点没有前驱结点；(2)当n>1时，除根结点外其余的结点分为m(m>0)个互不相交的有限集合T1,T2，…，Tm，其中每个集合Ti本身又是一棵结构和树类似的子树。 -Tree is n (n ≥ 0) consisting of nodes finite set T. n = 0 of the tree known as the empty tree for n> 0 of the tree, there is: (1) has only one special node called the root node, root node there is no precursor node (2) when n> 1 when, with the exception of root node except the node is divided into m (m> 0) a finite set of mutually exclusive cross-T1, T2, ..., Tm, one of each set Ti is itself a structure and are similar subtree tree .
