The Research Of SD Key In The System Of Wireless PKI

As the technology of mobile telecommunication is developing rapidly, M-Commerce will become the direction of E-Commerce development, and it also brings unlimited opportunities. In our country, banks, mobile operators and service providers are cooperating with each other to take out much more wireless applications. But at the same time M-Commerce is facing many security problems. We must find out an efficient resolution to solve them so that we can clean up people's troubles and strengthen their faith of M-Commerce. Because Smart Card can store and explain the private signature key and certificate so that it can realize digital signature and authentication and effectively protect the information security. The SD Key has so many advantages, such as high transmission speed, little bulk, plug and play, and easy to carry, that it will have good prospects in network security, especially in M-Commerce.This paper analyses the development of M-Commerce and the security problems it faces, and expatiate the technologies of network security. With the characters of mobile telecommunication, the author makes use of SD Key to solve a series of security problems. This paper analyses and design the inside and outside software of SD Key with the start of its physical and logic structure. This paper also designs the applications of SD Key on mobile terminal with the system of Microsoft CryptoAPI and works out a scheme of its application in the system of wireless PKI.
