摘要
针对GPRS系统接入安全风险大的特点,提出了与WPKI相结合的终端接入认证方案,并对该方案进行了分析研究。提出了将无线公钥基础设施(WPKI)应用于GPRS平台以获得应用层无线安全保障的方案。设计了一个将WPKI体系和GPRS平台结合起来的实验系统,给出了各个功能模块的逻辑和功能结构图,并基于开源代码库Openssl对试验系统中的CA服务器和RA服务器进行了实现和测试,在GPRS平台上实现了WPKI核心内容-证书申请、证书签发、证书查询、证书撤销等。经过测试,该实验系统能在实际的GPRS平台上可靠运行。
Aiming at the high-risk characteristics of the GPRS access security system, a terminal access authentication scheme in combination with WPKI is proposed and analyzed. The application of wireless public key infrastructure （WPKI） in GPRS platform is suggested for wireless application layer security plan. A experiment system in combination of WPKI with GPRS platform is designed, and the logic and function structure of various functional modules is also given. Meanwhile, based on open source code base Openssl, the CA server and the RA servers in the experiment system are implemented and tested. And the WPKI core contents such as certificate application, certificate issue, certificate inquiry, certificate revocation, and so on are implemented on the GPRS platform. Tests indicate that the experimental system can operate reliably on the actual GPRS platform.
