摘要
给出了一种概率验证方案，以决定匿名可分电子现金系统在支付时采用联机验证还是脱机验证，从而减少脱机电子现金系统由于用户的重复支付而产生的损失额．同时为消除由于加人概率验证方案而增加的支付时间，采用并行处理的方法以提高效率．
In this paper, a probabilistic audit scheme is presented to determine whether it is by on-line or by off-line that the payments are verified in an anonymous divisible e-cash system to reduce the loss caused by users' double-spending. A parallel processing method is used to eliminate the additional payment time by the probabilistic audit scheme.
