Abstract

A smart card-oriented remote login authentication scheme is presented. The proposed scheme can be divided into three phases: registration, login and authentication. In the registration phase, the registering user chooses a password only known to himself. The central authority (CA) assigns an identity for the user, and delivers a smart card to the registered user. The smart card contains some necessary public parameters used in the login and authentication phases. Based on some simple properties of Euclidean geometry, the login and authentication phases can be achieved easily. Impersonation and replay attacks on the proposed scheme are discussed.
