将Internet和嵌入式设备融入到逆变电源监控系统,将提高系统效率,推动电源技术应用的发展。但同时也带来一些新的问题,首要是网络安全。在逆变电源监控系统的安全需求背景下,首先分析嵌入式监控系统面临的主要的网络安全威胁,然后针对嵌入式系统资源有限的条件,参考GSM系统特有的安全机制,利用DES加解密算法,提出了解决方案,实现了安全和嵌入式系统资源使用的较佳平衡。
Applying Intemet and embedded equipment to inverters remote monitor and control system can improve the efficiency of the system and promote the development of technology of inverters. Meanwhile it brings new threats, first of which is network security. Under the security requirement of inverters remote monitor and control system, the paper analyses the key network security threats in the embedded monitor and control system, then brings forward the feasibility method of GSM security mechanism and DES encryption algorithm referring the limited system resource. It obtains the preferable balance between security and using resource.
