Single sign-on mechanism security enhancement for distributed computer networks


Harish Pote, Neha Patil, Deepali Gosavi

Distributed System Single Sign On is an authentication mechanism which allows a user with single credential authenticated by one or more than one Service Providers in Distributed System. Recently, Mr Chang and Mr Lee enhance their previous scheme and they claimed that proposed scheme is more secure than last one SSO mechanism. In this paper, System implement disadvantages of their scheme, their Single Sign On mechanism having two types of attacks, first one is a malicious service is communicate with the user successfully, then recover the credential and access service providing by another service. Second one is, illegal user without credential access the services by impersonating existent or non-existent user. Their scheme is based on RSA Encryption; we implement their disadvantages by using efficient Digital Signature with RSA for enhance more security.
