A SECURE SYSTEM IN DISTRIBUTED COMPUTER NETWORKS USING SINGLE SIGN-ON MECHANISM

Abstract

 In the distributed computer network environment, it is easy for user terminals to share information and computing power with hosts. Accessing of resources becomes efficient and convenient because of the distributed locations of service providers. A Single Sign-On is a method of access control that enables a user to log in once and gain access to the resources of multiple software systems without being prompted to log in again. This scheme is based on one-way hash functions and randomly used to decrease the overhead of the system. In this Paper a secure system with single sign-on mechanism is proposed which allow mobile users to use the unitary token to access service providers.
