摘要: In 1999, Hwang and Li proposed a new user authentication scheme using smart cards. The does not need any password or verification table. Later, Sun an efficient remote use to improve the efficiency of Hwang-Li scheme. However, these two schemes do allow users freely choose change their passwords. this article, we shall propose simple that allows passwords without significantly increasing computation cost.
