Abstract


Because of its off-line electronic cash transactions, user anonymity, convenient and flexible, can effectively prevent the protest and malicious overdraft and other characteristics to become e-commerce one of the most important methods of payment, and has become the trend of the future development of electronic money. Severability is a basic currency of any kind, the natural properties of electronic cash can be divided not only used as a whole, can be divided into smaller parts used repeatedly, the user can reduce the number of withdrawals, Network Communications therefore significantly reduce the amount of system implementation efficiency has improved significantly. Therefore, the separability of electronic cash has always been the focus of research in the field and focus. To really move towards electronic cash can be divided into practical applications there are a lot of work to do. Duplicate payments, overpayments detection makes divisible e-cash protocol becomes complicated, resulting in increased computational complexity of the agreement, the efficiency decreased; introduction of a trusted third party to track the illegal users to avoid complicating the agreement, but can not guarantee the user's anonymity, and the introduction of a trusted third party will increase the system overhead; different parts of the same e-cash is often a correlation (not entirely without connectivity), there is a potential threat to users' privacy disclosure. This article is committed to exploring new ideas and the use of new techniques to build more excellent performance, efficiency can be divided into more efficient electronic cash scheme. First, summarizes and analyzes the key technologies for electronic cash, including the realization of electronic cash separability various techniques to analyze the advantages and disadvantages of the related art. Secondly, in the traditional binary technology, based on good ideas and actively explore new technologies is proposed to improve the separability of two new electronic cash scheme: The first option, by constructing efficient interactive zero-knowledge proof, to achieve a electronic cash completely free connectivity, which means that users use the same e-cash transactions for different users will not disclose any confidential information, and will not divulge any electronic cash paid related nodes, while overcoming the program the existence of a trusted third party; second option is to try to improve the efficiency of electronic cash scheme can be divided into a useful attempt. Program in the withdrawal phase of the introduction of probabilistic algorithms, combined with the one-way accumulator is bounded for authentication, choose to avoid the traditional segmentation algorithm, effectively improve the efficiency of the implementation, programs to overcome the existence of a trusted third party, the realization of the electronic Cash no connectivity. Finally, points out the existing problems can be divided into electronic cash and further research work are put forward.
