Soundness to Single Sign on Using OTP in Distributed Networks

Abstract

In a distributed system, there are numerous service provider. The user must be authenticated to entrance the services provided by the service provider. It is challenging to recall all secret words for users. So to clarify this problem single sign on is used which is an authentication contrivance in that permit a single license to be validated by multiple service provider. The Wang, Yu, and Qi Xie find that Chang - Lee Scheme undergoes from two attacks one of which is that the aggressor is outside service provider converses with the authenticated user twice and get the license necessary to right to use data in distributed systems. The second attack is the outsider easily receiving right to use to, use services without any license by mimicking authenticate user. This violence also associated with Hsu and Chang Scheme. To sidestep these attacks Wang, Yu, and Qi Xie employed RSA-VES. For enhancement and soundness of authentication, this paper services One Time Password to Wang, Yu, and Qi Xie Method. Now a days OTP plays important role in an authentication, so that using OTP for secure single sign on its easy to provide soundness for authentication.
