Abstract
In this study, we propose a practical and secure hash function-based password authentication scheme using smart cards. Our proposed scheme offers some advantages and interesting features. Firstly, the scheme does not require a verification table and is secure against the replay attacks, an attack that most of the existing schemes suffer. Secondly, any user of the scheme be allowed to change his or her account’s password efficiently. Thirdly, the time complexity for each algorithm in the proposed scheme are relatively low and minimal compared to some existing well-known password authentication schemes.
Highlights
The global network channel with today’s technology is a must for it conveniently provides access to various type of online services through remote systems, an open system that enable users from over the world to communicate confidently and safely
The open environment of this kind communication has normally led to the source of security risks and threats
Some previous verification tablebased password authentication schemes were not designed to withstand replay attack, an attack where an intruder observes on a secure network communication, intercepts a message and fraudulently delays or resends the message to misdirect the receiver into doing what the intruder wants
