Paper Abstract

Based on the law of quantum mechanics we present a simple authorization scheme: Quauth. The description of the scheme is given in details. The authorization is accomplished through a quantum channel by one way communication. We show that eavesdropper gets no information about key no matter how many times s/he is listening on the channel. The scheme is robust against both the passive and active attacks. By induction we prove that the scheme is information theoretically secure.
