Describe the three way handshake process as used by CHAP.?

What will be an ideal response?

The handshake process used by CHAP is as follows:challenge-The server sends the client a randomly generated string of characters.response-The client adds its password to the challenge and encrypts the new string of characters. It sends this new string of characters in a response to the server. Meanwhile, the server also concatenates the user's password with the challenge and encrypts the new character string, using the same encryption scheme the client used.?accept/reject-The server compares the encrypted string of characters it received from the client with the encrypted string of characters it has generated. If the two match, it authenticates the client. But if the two differ, it rejects the client's request for authentication.
