Here are the correct pairings: 1. Password Authentication Protocol: A representation of the user's password transmits during authentication instead of the password itself. 2. Shiva Password Authentication Protocol: The user's name and password transmits during authentication in unencrypted form. 3. Challenge Handshake Authentication Protocol: The user's name and password transmits during authentication in an encrypted form.
Password Authentication Protocol (PAP):
- Description: A representation of the user's password transmits during authentication instead of the password itself.
- Explanation: PAP involves sending a hashed or encrypted version of the user's password for authentication rather than sending the actual password in plaintext. This provides a basic level of security.
Shiva Password Authentication Protocol (SPAP):
- Description: The user's name and password transmits during authentication in unencrypted form.
- Explanation: SPAP, in contrast to more secure protocols, transmits the user's credentials without encryption. This makes it vulnerable to eavesdropping, posing a security risk.
Challenge Handshake Authentication Protocol (CHAP):
- Description: The user's name and password transmits during authentication in an encrypted form.
- Explanation: CHAP enhances security by transmitting the user's credentials in an encrypted form. Additionally, it involves a challenge-response mechanism, adding an extra layer of protection against unauthorized access.
