Abstract


Along with the rapid development of the computer network technology, the usage of e-commerce has been applied widely. The research on the electronic payment of e-commerce is important not only in academic value, but also to national financial institutions of information construction and national economic development is significance. No appropriate mechanism to solve the problem of online payment, e-commerce in the development of the Internet will be restricted. Electronic cash, as an important means of electronic payment, now is still in the research and development stage. How to solve the problem of efficiency, security and divisible of electronic cash, are also technical problems and have not been completely resolved. The main results of this thesis including:1. Research on the theory of e-cash and e-cash schemes. Analysis the e-cash scheme based on RSA and Brands e-cash scheme, summing up the mathematical difficulties involved in the schemes as well as the existing problems in the schemes.2. Study of the divisibility of e-cash. The divisible e-cash schemes can be classified as based on the binary tree and based on the trusted third party two methods. Research on the principle of two methods, given the theoretical framework and analyses the practicality of two methods, summing up the existing problems of two methods.3. In allusion to the existing problems of e-cash scheme, put forwards partial blind signature in e-cash scheme. Theoretical analysis is made to the system performance. Since the withdrawal phase of the scheme in the use of the partially blind signature, to abandon the inefficient cut-and-choose blind signature technology, therefore, to a certain extent, guarantee the safety of the scheme and to enhance the efficiency and to prevent the multiple electronic cash to spend. Finally, do simulation of the new scheme. The results show that the new approach practical, safe and more efficient.
