A simple password protocol that transmits a user name and password
across the network, unencrypted, abbreviated as PAP.
PEAP (Protected EAP)

authentication methods. PEAP features include: Dynamic Key Exchange;
Mutual Authentication; and, Encrypted Tunnelling.
Point-to-Point Protocol
The standard protocol for dial-up networking. The family of standards
covers many aspects including authentication, encryption, compression,
addressing, multi-protocols, etc., abbreviated as PPP.
Policy
A very broadly used term. To the AAA server, it means the conditionally
applicable set of attribute-value pairs that an AAA protocol, such as
RADIUS, may support. HP-UX SERVER policies are simple or complex
decisions that control the authentication, authorization, and accounting
process for a user's access request.
PPP
See Point-to-Point Protocol.
Protocol
A set of rules established between two devices to allow communications to
occur.
Proxy
The mechanism that allows one system to mediate between two other
systems in response to protocol requests. A RADIUS server can act as a
proxy client and forward an Access-Request to another AAA server for
authentication. As a proxy client, the server would mediate the requests and
replies between the client where the Access-Request originated from and
the server that the request was forwarded to.
RADIUS
See Remote Access Dial In User Service.
