Create the Authentication Scheme

You can use any of the following authentication schemes:

• Password Authentication Protocol (PAP)

  PAP is a PPP authentication protocol that provides a simple method for a host to establish its identity in a two-way handshake. Authentication takes place only upon initial link establishment and does not use encryption.

• Challenge Handshake Authentication Protocol (CHAP)

  CHAP is also a secure PPP authentication protocol. CHAP provides a way to periodically verify the identity of a host using a three-way handshake and encryption. Authentication takes place upon initial link establishment. The RAS can repeat the authentication process any time after the connection takes place.

• Security Dynamics ACE/Server or Secure Computing SafeWord server.

Note: For more information on creating an authentication scheme, see the Authentication Schemes chapter in this guide.
