Research On Electronic Money And Key Technologies In Electronic Payment

Research on electronic money is popular recently.But much was focused on how to realize certain functions without proving if those functions are necessary .Most important of all,nobody knows which functions can build a perfect electronic money model.The offline continuous payment model of electronic money was introduced from JW model,N.A model,3E model,etc.Eight atomic function attributes were deduced from comparing with paper currency and the requirements of offline continuous payment model.They are Anonymity,Currency Value, Uniqueness,Verifiable Offline,Falsify Forbidden,Copy Forbidden,Payable and Storable.Key technologies of electronic money were analyzed deeply based on the offline continuous payment model and atomic function attributes .Many important results were obtained.The perfect function model of e-money was introduced from the atomic function attributes and the offline continuous payment model.The way of future research on electronic money was directed by the offline continuous payment model,the perfect function model,the atomic function attributes,and the results of research on key technologies.
