嵌入式浏览器中SSL的设计与实现

Design and Implementation of SSL in Embedded Browser

针对嵌入式浏览器信息传输的安全性问题和嵌入式软件的特点,介绍了SSL协议,提出了一种在嵌入式浏览器中实现对SSL协议支持的方法。通过分析影响SSL协议客户端性能的因素,对SSL的实现过程进行了适当的优化,使用会话恢复机制、只对服务器进行验证的简单握手模式、减少TCP调用次数和优化对批量数据加密算法等方法,实现了嵌入式浏览器对SSL协议的支持;并介绍了方法在嵌入式浏览器JARI_Browser中的实现过程,实际的应用验证了该方法的可行性和正确性。

Aiming at the security problems of information transfers in the embedded browser and the embedded software features,the paper introduces the SSL protocol and puts forward a method which implements the SSL protocol in embedded browser. By analyzing the SSL protocol＇s client performance factors, the paper use session resume mechanism, only server verify handshake mode, reduce the TCP connections and optimize the bulk data encryption algorithms, resolved the problem above. By researching with JARI_Browser, the application validates the feasible and accurate of our method.
