Contents Error and Security Analysis of 'Security Analysis and Improvements of a Biometrics-based User Authentication Scheme Using Smart Cards'

Abstract

In this paper, we analyze weaknesses of the biometrics-based user authentication scheme proposed by An. The result of analysis An's authentication scheme by the login success scenario proposed in this paper, if the attacker successes to get user's random number, he/she can pass user authentication phase of the legal server. Also the biometrics guessing scenario proposed in this paper shows the legal user's the biometric information is revealed in lost smart card. Since An's authentication scheme submit user ID•제1저자 : 박미옥 •교신저자 : 오기욱
