CHALLENGE HANDSHAKE AUTHENTICATION PROTOCOL
PAP
PASSWORD AUTHENTICATION PROTOCOL

2
Authentication Mechanism
learntorise
CHAP
PAP
Mutual authentication process, both the client
and the server authenticate each other's
identities
One-way authentication process, only the
client authenticates with the server

3
Password Transmission
learntorise
CHAP
PAP
Sends the encrypted password
Sends the password in plain text

4
Security
learntorise
CHAP
PAP
More secure due to the password not being sent
directly and uses a challenge-response
mechanism
Less secure due to plain text password
transmission and easily interceptable

5
Frequency
learntorise
CHAP
PAP
Periodic (frequent re-authentication)
Authentication typically occurs only during the
initial connection setup

6
Complexity
learntorise
CHAP
PAP
More complex and sophisticated to implement
Simpler to implement

7
Vulnerabilities
learntorise
CHAP
PAP
Resistant to eavesdropping and replay attacks
Vulnerable to eavesdropping and replay attacks

8
Use Cases
learntorise
CHAP
PAP
Suitable for long-lasting connections
Suitable for low-security scenarios
