Abstract:Since the computing power and storage space of mobile handle terminal were very poor, this paper introduced a mobile payment system based on elliptic curve cryptosystems. Compared with previous ecash systems based on RSA or discrete logarithm, the new system required much shorter security parameter size and it was convenient to be expanded. Moreover, the storage, the computation and communicating efficiency were improved in the new system, at the same time, all the security features for mobile payment were kept as usual. Furthermore, the system can prevent from double spending, fraud and perfect crime effectively.......
