Single Sign-on Secure Password Mechanism for Distributed Computer Networks

Deepali M. Devkate | N. D. Kale ^[7]

Abstract: Single sign-on mechanism is an authentication mechanism in which user sign on only once but their identities verified by many services they want to access later. Practically, it happens that if you wish to access any service then identification of user is an important task. So first you have to register for that service then you become authenticated user. Suppose you want to access many services then you have to create different set of credentials and memorize it. But in proposed system user need only one credential to access many services in distributed computer network. In existing system two types of attacks are found. i. e. impersonation attack and session attack. In impersonation attack, a bogus service provider is able to hack up the credential of authorized user. In session attack, an unauthorized user is able to enjoy the resources and services accessible by service providers. In proposed research work, credential privacy and soundness is protected. By using Diffie-Hellman Key Exchange and Elliptic curve Encryption Algorithm authentication is secure.
