摘要
提出一个量子动态口令方案.方案将敌手攻击时间有效地压缩,以抗重放攻击.方案是一个单向通信和统计安全的口令认证协议,在保证一定的统计安全性条件下,相比经典动态口令方案显著提高了种子可重用次数.
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.
