Research Of Security Frame Based On WAP & Software Realization Of WTLS

With the development of wireless network , the condition of developing mobile commerce based on it comes to the pointSecurity problem as the first barrier on the way of develop must to resolve quickly.Nowadays, there are many mobile commerce reseachs & applications are based on WAP.a open and widely used protocol,the security frame based on it is the research object of this project so.This work analysises the elements of security frame-WTLS,WEvI,WMLScript and WPKI, describes how that collaborate.In paper,some unclear information and concepts in WAP specification are summarized and described clearly,such as ,the way of using WTLS and X509 Cert to build Unstable relationship.among mobile terminal,Web server,WAP gateway and wireless CA; the way of End-to-End security in wirless network,etc. Futhermore, the thesis anatomizes the WTLS protocol and describes the WTLS software design and realization. According to the principle of software modularization,software is divided into several modules.The module of state machine is the most important, realization of which is the core of work. In order to convenience the reader to understand the security technology, this thesis introduces the concept of that first.In this project, I took part in the reaserch of the subjiect, and took charge of the designing and development of the WTLS software, and took long time to debug and transplant the program in several target environments , to mak it become a steady product. In the end of this thesis, I describe the solution of difficulties I meet in the procedure for debugging.
