基于SSL/TLS的嵌入式网络通信安全解决方案

Embedded technology has been widely applied in network communication field due to the growth of embedded technology and increase of network communication requirement. At the same time there are also secure problems found in some of those network embedded devices. We should pay attention to those potential secure problems, because they are big threats for user information security. In order to solve network communication secure problems, some of the most effective methods are authentication and data encryption technology.In this paper, the author analyzed the embedded device network security requirement and discussed a simple method to implement embedded system network secure communication based on PKI digital certificate system and SSL/TLS protocol. The OpenSSL which is a useful tool kit for developers is also introduced for engineering implementation.
