Comments on a password authentication and update scheme based on elliptic curve cryptography

Debiao He

Abstract

The security of a password authentication and update scheme based on elliptic curve cryptography proposed by Islam et al. [S.K. Hafizul Islam, G.P. Biswas, Design of improved password authentication and update scheme based on elliptic curve cryptography, Mathematical and Computer Modelling (2011), doi:10.1016/j.mcm.2011.07.001] is analyzed. Three kinds of attacks are presented in different scenarios.
