Abstract:

                As single sign-on (SSO) provides access to many resources once the user is initially authenticated. It increases the negative impact in case the credentials are available to other persons and misused. Therefore, single sign-on requires an increased focus on the protection of the user credentials, and should ideally be combined with strong authentication methods .Further attack split into two types there are malicious service provider attack and attack an outsider. Here the investigation focus foe overcome these limitation so in this method use the RSA signature for user initiation process.
