A secure and robust smart card-based remote user authentication scheme

In the new era of technology, smart cards play a critical role in economic and social interactions. Security vulnerabilities of these smart cards are the main concern for many users as well as researchers. Authentication has been used as one of the basic security solution to protect the data from unauthorised access. In recent years, smart card-based password authentication has gotten more attention by researchers. This paper reviews different smart card authentication methods and proposes an improved authentication method to cover existing security weaknesses including security of verification. Finally, the proposed method is analysed and compared to the related works.
