In the Internet and Mobile communication environment, authentication of the users is very important. Although at present password is extensively used for authentication, bare password transmission suffers from some inherent shortcomings. Several password-based authentication methods have been proposed to eliminate such shortcomings. Those proposed methods have relative demerits as well as merits. In this letter we propose a method where those demerits are eliminated. The prominent feature is security improvement apart from low processing, storage and transmission overheads compared to previous methods. This method can be used in several applications like remote login, encrypted and authenticated communication and electronic payment etc.
