The Security Study Of Mobile Commerce System

With the rapid progress of the Internet technique and wireless network technique,mobile commerce has a large potential force as the new developing aim of e-commerce,moreover, the problem of network security becomes more and more serious.Cryptosystems are critical to solve the problem. Elliptic curve cryptosystems are onekind of the most promising public key cryptosystems. As their advantages of securities,efficiencies and implementation costs over other public key cryptosystems, ellipticcurves cryptosystems are getting broadly applied and adopted by many criteriaorganizations as one of their public key cryptosystem standards. Because the newscheme is based on Elliptic curves and integrates threshold-authenticated scheme,division-of-labor signcryption with message linkage and the idea of individual secret key,it accelerates calculation speed, shortens the time of data transmission, reduces theworkload on the signer. If the mobile commerce makes use of the new scheme, networkcommerce becomes more efficient and more secure.
