Expansions of CHAP: Modificationless on its structures of packet and data exchange

I propose new authentication protocols using/unmodifying the structures of packet and data exchange on CHAP (Challenge Handshake Authentication Protocol). CHAP is one of the most popular authentication protocols because of very simple scheme and no vulnerability of its structures of packet and data exchange. Therefore, this protocol is used a lot of services over the Internet as de facto standard. However, unlawful access often happens caused by users' mistakes of password setting, e.g. password-list-attacks, and proposing/implementation of other authentication methods without using password are urgent. To solve the problem, I propose new scheme which can send many type of authentication codes using intact CHAP. By using my proposal, other authentication method using password authentication together can be realized with a minimum cost burden.
