<abstract>
<t>The Point-to-Point Protocol (PPP)provides a standard method for transporting multi-protocol datagrams over point-to-point links.  PPP defines an extensible Link Control Protocol and a family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.</t>
<t>This document describes version two of Microsoft's PPP CHAP dialect (MS-CHAP-V2).  MS-CHAP-V2 is similar to, but incompatible with, MS-CHAP version one (MS-CHAP-V1, described in. In particular, certain protocol fields have been deleted or reused but with different semantics.  In addition, MS-CHAP-V2 features mutual authentication.</t>
<t>The algorithms used in the generation of various MS-CHAP-V2 protocol fields are described in section 8.  Negotiation and hash generation examples are provided in section 9.</t></abstract></front>
