Implementation of Single Sign-On Mechanism for Distributed Computing?

With wide spreading of distributed computer networks, it has become popular to allow users accessing various network services offered by distributed service providers. It is usually not practical by asking one user to maintain different pairs of identity and passwords for different service providers, since this could increase the workload of both users and service providers as well as the communication overhead of networks. So, for this it requires a single sign-on authentication mechanism that is a single login for multiple service providers, which would not increase the workload. There are various attacks and parameters that need to be considered while providing security to authentication system. In this paper, we provide a comprehensive review of existing work done on Single sign-on. Then for security of single sign-on, what parameters and attacks should be covered. Next, Implementation of Single Sign-on for distributed computing using user-id and password along with biometric verification. Then security analysis is done. Next, we present the comparison and lastly we conclude, specifying the future work.
