ADVANCED MECHANISM FOR SINGLE SIGN-ON FOR DISTRIBUTED COMPUTER NETWORKS

Abstract

A distributed computer networks could be a special form of the network that facilitates the purchasers to use completely different network services that is provided by the service suppliers. Within the distributed computer networks, user verification is a crucial method for the protection. Within the verification, the choice is taken whether the user is legal or not and then enabled the users to access the service. In general users are using multiple usernames and passwords for to access different applications on a distributed computer network. This increase the burden of the user and organization administrator as each and every account of the organization is going to be handled with their explicit username and credential. A new certification plan that is named as single sign-on mechanism that facilitates the users with one identity token to be verified by multiple service suppliers. Single signon is one of user authentication method that allows a user to enter one name and identity token so as to access multiple applications. The method authenticates the user for all the applications they have been offered access to and eliminates additional prompts after they switch applications throughout a specific session. However, existing approaches which are utilizing single sign-on scheme have some drawbacks relating to security needs. Thus, through this paper, we will discuss regarding the event of security from earlier stage to present stage. And clearly discuss regarding the authentication steps between user and service supplier.
