Secure Authentication of DistributedNetworks by Single Sign-OnMechanism

Credential of the technology is missing in the recent system. So, to improve the authentication of the distributed networks or multiple applications we are making use of a single sign on mechanism. Previously, users were using n number of usernames and passwords to access different applications on network. This would lead to higher expense for the administrator as each and every account of the organization will be handled with their particular username and password. But, now user needs to remember just single secure credential to access the multiple service providers in a distributed network by using single sign-on mechanism. However, most existing systems which are using this mechanism have some disadvantage regarding security requirements. So through this paper we will discuss about the development of security from earlier stage to present stage. And also discuss about the structure of the mechanism’s working strategy.
