Secure Applicactions of Elliptic Curve Public Cryptosystem in the Electronic Commerce
Lu Chen · Jisuanji gongcheng · 2002
The elliptic curve public cryptosystem is a key of crytographic deploy of handheld secure access devices in electronic commerce system. This paper describes the mathematics base of ECC and discusses the elliptic curve discrete logarithm problem (ECDLP) and the security applications of ECC on E-commerce. A fast arithmetic of ECC is given and this make it possible that ECC's practical applications in the electronic commerce. It is proven that the elliptic curve cryptosystem (ECC) provides the highest strength-per-bit of any cryptosystem known today in the last.
