CHAP
Challenge-Handshake Authentication Protocol (pronounced as a new word: chap)
A secure procedure for validating a network connection request. After the link is established, the server sends a "challenge message" to the requestor, who responds with encrypted authentication information (the username and password), based on a "key" in the challenge message. If the server is able to decipher the message using the original key, the authentication is acknowledged. If not, the server terminates the connection.
