What is chap checksum?
A CHAP (Challenge-Handshake Authentication Protocol) checksum is part of a security mechanism used in network communications to verify the identity of a user or device. During the authentication process, the server sends a challenge to the client, which then responds with a hash value generated using a shared secret and the challenge. This checksum helps ensure that the response has not been tampered with and confirms the authenticity of the client without transmitting the actual password. CHAP is commonly used in point-to-point protocol (PPP) connections.
The protocols used to encrypt account names and passwords are called authentication protocols The two most popular protocols are and Kerberos?
CHAP (Challenge Handshake Authentication Protocol) The CHAP provides protection against palyback attack by the peer also requires both the client and server.
What hash algorithim is used by common implementations of CHAP?
Common implementations of the Challenge Handshake Authentication Protocol (CHAP) typically use the MD5 hash algorithm. CHAP uses a challenge-response mechanism where a server sends a challenge to the client, which then computes a hash of the challenge and its password to respond. Although MD5 is widely used, it is considered less secure by modern standards, and more secure alternatives are recommended for sensitive applications.
Which combination of Layer 2 protocol and authentication should be used to establish a link without sending authentication information in plain text between a Cisco and a non-Cisco router?
PPP with CHAP
Which authentication protocol can be spoofed to allow playback attacks?
The Challenge-Handshake Authentication Protocol (CHAP) can be spoofed to allow playback attacks. In CHAP, the server sends a challenge to the client, which then responds with a hashed value combining the challenge and the password. If an attacker captures this exchange, they can replay the hashed response later, potentially gaining unauthorized access. This vulnerability arises because CHAP does not provide sufficient protection against replaying previously captured responses.
What is the first protocol used by the ARPANET?
The first protocol that was used by the APARNET was called the Internet Protocol.
Difference between serial line internet protocol and point to point protocol?
PPPis more secure than SLIP. PPP uses two authetication Protocols : 1. Password Authetication Protocol (PAP) 2. Challenge Handshake Authetication Protocol (CHAP) So if you use SLIP on network that unauthorized user can gain acces to.
