Compare and Analysis of Security Strategy in WAP and I-Mode Network

This paper presents the security strategy used by WAP and I-Mode. It includes security transport protocol, the type of certificate, the performance of gateway, smartcard and authenticate scheme. It will first be illustrated from the architecture, and then discussed application situation. All of these schemes of WAP will be compared with the similar adopted technology of I-Mode. Through comparing, deficiencies of both WAP and I-Mode were uncovered. Methods to resolve these security problems were proposed at the end of this paper. The overall results derived from this work show WAP has more detailed, more general and more secure security scheme than I-Mode.
