基于OpenSSL的嵌入式网络安全通信设计与实现

Design and Implementation of Embedded Network Secure Communication Based on OpenSSL

嵌入式网络安全设备的通信,如对设备的状态查询、配置等必须是安全的。文中探讨了嵌入式网络安全设备的远程安全通信设计。首先分析了OpenSSL的工作原理、数字证书在OpenSSL中的重要作用;然后给出了在嵌入式网络安全设备中进行远程安全通信的总体设计方案,并结合笔者一个实际的嵌入式网络安全设备的开发项目,详细介绍了其设计与实现过程。通过这种方法可以达到相对较高的安全通信要求。

The communication of embedded network secure devices, such as status query and configuration of devices should be secure, Discusses the design of remote secure communication on embedded network devices. After analyzing the principles of OpenSSL and the key role of digital certification in OpenSSL, gives out a general design scheme of remote secure communication on embedded network devices. Combined with the authors＇ project developed on an actual embedded network secure device, has illustrated the overall design and implementation procedure in detail. The requirement of communication with high security can be met in such a way.
