Abstract:In a classical dynamic password authentication system(CDPAS), the password changes with time to get the 'one time pad' security. The hash function is computationally secure. Thus the CDPAS is not statistically secure. We propose a quantum dynamic password scheme. It compresses the attack time period and resist the replay attack. It is statistically secure and significantly enhances the reusing times of the seed compared to the CDPAS.
