ENHANCED KERBEROS AUTHENTICATION FOR DISTRIBUTED ENVIRONMENT
Angelin Gladys Jesudoss · 2014
This paper aims to provide a unique and enhanced authentication model based on Kerberos environment. With this, it provides a hack-proof authentication system and protects the Kerberos environment from password-guessing attack and replay attack. Traditionally, the banking and financial institutions sends OTP to the client mobile. When it is hacked, the identity can be compromised. Using the proposed authentication model, even when the nonce value or the OTP is hacked, the identity cannot be compromised. This paper insists the need for an additional Session Key and a nonce to be used between the Authentication Server (AS) and Client i.e. Alice. This helps to make the security stronger. Kerberos environment is prone for replay attack and password-guessing attack and hence this security model helps Kerberos environment to prevent such attacks.
