A Secure YS-Like User Authentication Scheme

A Secure YS-Like User Authentication Scheme Recently, there are several articles proposed based on Yang and Shieh's password authentication schemes (YS for short) with the following features: (1) A user can choose password freely. (2) The server does not need to maintain a password table. (3) There is no need to involve a trusted third party. Although there were several variants of the YS-like schemes claimed to address the forgery attacks, this paper analyzes their security and shows that they still suffer from forgery attacks. Furthermore, a new scheme based on the concept of message authentication is proposed to foil the forgery attack. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Informatica IOS Press

Abstract

Recently, there are several articles proposed based on Yang and Shieh's password authentication schemes (YS for short) with the following features: (1) A user can choose password freely. (2) The server does not need to maintain a password table. (3) There is no need to involve a trusted third party. Although there were several variants of the YS-like schemes claimed to address the forgery attacks, this paper analyzes their security and shows that they still suffer from forgery attacks. Furthermore, a new scheme based on the concept of message authentication is proposed to foil the forgery attack.
