Mutual Authentication Protocol for HTTP
Abstract
This document specifies an authentication scheme for the Hypertext
Transfer Protocol (HTTP) that is referred to as either the Mutual
authentication scheme or the Mutual authentication protocol. This
scheme provides true mutual authentication between an HTTP client and
an HTTP server using password-based authentication. Unlike the Basic
and Digest authentication schemes, the Mutual authentication scheme
specified in this document assures the user that the server truly
knows the user's encrypted password.
