What is the difference between Kerberos and NTLM?

The main difference between NTLM and Kerberos is in how the two protocols manage authentication. NTLM relies on a three-way handshake between the client and server to authenticate a user. Kerberos uses a two-part process that leverages a ticket granting service or key distribution center.

What protocols use NTLM?

Windows Challenge/Response (NTLM) is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems. The Microsoft Kerberos security package adds greater security than NTLM to systems on a network.

What is the difference between NTLMv1 and NTLMv2?

The difference lies in the challenge and in the way the challenge is encrypted: While NTLMv2 provides a variable-length challenge, the challenge used by NTLMv1 is always a sixteen byte random number. NTLMv1 uses a weak DES algorithm to encrypt the challenge with the user’s hash. … NTLMv2 uses HMAC-MD5 instead.

What is Kerberos Key?

Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users’ identities.

Is NTLMv2 a Kerberos?
