Kerberos plays an important role in Authentication of Clients & Servers in a distributed system. Many works have analyzed its security, identifying flaws and often suggesting fixes, thus promoting the protocol's evolution. Several recent results present successful, formal methods-based verifications of a significant portion of the current version. Traditional kerberos is vulnerable to password guessing attack. To remove this weakness, there is a proposed scheme on dynamic password based authentication. In proposed protocol, use of AES Encryption & SHA1 algorithm for hash improves the security of kerberos environment.
