Anonymous divisible E-cash protocol based on PBOC IC card
基于PBOC智能卡的匿名可分电子货币协议

In this paper,a new anonymous divisible E-cash protocol was proposed,by making use of the physical security of PBOC2.0 IC Card,to support off-line transaction.The proposed protocol is more efficient than those based on partial blind signature or zero-knowledge proof.It also integrates a control mechanism to regulate withdrawal,payment,loss reporting and deposit of coins,so as to erase the relationships among different coins and maintain anonymity.Moreover,security was proved under both cryptology principles...
