- CHAP :
- Challenge Handshake Authentication Protocol
Challenge Handshake Authentication Protocol (CHAP) is a security protocol used to authenticate users over a network. CHAP involves a three-step process:
- the server sends a challenge to the client
- the client responds with a hashed value based on the challenge and its password
- the server verifies the response.
This process helps ensure that passwords are not transmitted over the network, enhancing security against eavesdropping and replay attacks.
