ZigBee消息在应用层的安全机制研究

ON SECURITY MECHANISM OF ZIGBEE MESSAGES IN APPLICATION LAYER

通过对ZigBee通信协议的网络安全结构、加密算法的分析,提出可在应用层阶段加强ZigBee消息的安全性。然后通过对SOAP消息安全架构的研究和借鉴,并结合DES加密算法的原理,针对应用层的传递消息设计出加强消息安全的架构。与ZigBee协议中的原有的加密系统相比,不仅提高了加密效率,而且加强了密钥建立与管理的安全性,进而加强了内网安全性,对ZigBee通信网络的发展有重要的现实意义。

Based on analysing the network security architecture and encryption algorithm of ZigBee communication protocol, we propose that the security of ZigBee message can be strengthened in the phase of application layer. Then we design the architecture of message security strengthening in light of the delivery of message in application layer by studying and learning from SOAP message security architecture and in combination with the principle of DES encryption algorithm. Compared with the original encryption system in ZigBee protocol, this architecture improves the efficiency of encryption and strengthens the security of key establishment and management, thus enhances the security of internal network. This has important practical significance in the development of ZigBee communication network.
