A Fault-Tolerant Legion Authentication System

Protecting resources from unauthorized access are one of the most premier requirements of any distributed environment. Legion uses an Authentication Object that represents the user to system. AuthenticationObject is responsible for authenticating user and issuance of certificate, which is used by resource object to check validity of request. AuthenticationObject contains the password and private key of the user. User will access AuthenticationObject by using legion object identifier (LOID) containing public key of the user. If the AuthenticationObject gets deleted then there is no way to recover or regenerate th is AuthenticationObject because private key cannot be recreated. Thus, current system is not fault-tolerant and reliable. Therefore, user needs to be recreated. This paper proposes a fault-tolerant, reliable and more dynamic authentication mechanism
