| Abstract(in English) | The smart card with the cryptography and VLSI technologies makes us implement the electronic cash easily.A number of electronic cash schemes have been proposed by many researchers.In this paper, we propose practical electronic cash system using blind digital signature scheme,Schnorr′s authentication scheme based on the disc rete logarithm problem,and the hierarchical cash tree based on two one-way hash functions for dividability of cash.This electronic cash scheme has the following properties: privacy of the payment, off-line payment,non-reusability of cash,transferability of cash to another customer,and dividable payment of cash.Considering that the computational complexity of Schnorr′s authentication scheme is less complex than other schemes in smart card,this protocol is well suited for implemting in smart card. |
