Summary :

Recently, Lin, Hwang, and Li proposed an efficient remote authentication scheme using smart cards for multi-server architecture based on the geometric property of the Euclidean plane. Herein, we show that their scheme is vulnerable to two forgery attacks and a password-guessing attack, and is not easily repairable. Furthermore, their scheme lacks a proper user eviction mechanism.
