A Secured and Improved Dynamic ID based Remote User Authentication Scheme using Smart Card and Hash Function for Distributed Systems
Journal Title: International Journal on Computer Science and Engineering - Year 2014, Vol 6, Issue 8
Abstract
Authentication is a major concern for accessing remote service residing over on server in an distributed systems. It is difficult to remember different identities and passwords for users. In order to solve the flaws encountered in many remote user authentication schemes in multi-server environment, only authentic user login to the remote server has been used. These remote schemes resist various attacks and have some weakness. Leu and Hsieh proposed an efficient and secure dynamic ID based remote user authentication for distributed environment using smart cards but is vulnerable to impersonation attack, leak verifier attack, stolen smart card attack. We propose a strong authentication scheme with user anonymity and secured dynamic ID based remote user authentication using smart cards that remove aforementioned weakness in distributed systems. The function and performance efficiency of our scheme was analysed and proved to provide a strong mutual authentication between user and server when compared with the existing methods.
