Abstract

With mobile terminal increase, E-Commerce is transforming to M-Commerce. However, mobile security is one of the most urgent, and complex challenges to mobile payment because of mobile networks openness. The suitable cryptosystem of mobile communication equipment should possesses small amount of data calculating and rapid operation velocity because of its inherent limitations of small volume, low calculating capability. The purpose of this paper is to explore mobile payment and security. The paper discribes an elliptic curve methods in enciphering / deciphering, authentication of security wireless environment. Compare to traditional RSA cryptosystem, an elliptic curve has shorter key lengths, shorter signature size, low calculating, rapid velocity and high security in use. In the final sections we briefly discuss quantum protocol.
