逆变电源监控网络的安全机制 辛丽莉, 吴长奇 ( 燕山大学信息工程学院, 河北秦皇岛066004) : 将Internet 和嵌入式设备融入到逆变电源监控系统, 将 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, 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 : 逆变电源; 嵌入式; 网络安全; DES; GSM : TP393 : A : 1003- 3114( 2007) 04- 47- 3 Mechanism of Security in Network Monitoring System of Inverters XIN Lii, WU Changqi ( Information Engineering Co ege , Yanshan University , Qinhuangdao Hebei066004, China) Abstract: App ying Internet and embedded equipment to inverters remote monitor and contro system can improve the eff iciency of the system and promote the deve opment of techno ogy of inverters. Meanwhi e it brings new threats, f irst of w hich is netw ork security. Under the security requirement of inverters remote monitor and contro system , the paper ana yses the key network security threats in the embedded monitor and contro system , then brings forward the feasibi ity method of GSM security mechanism and DES encryption a gorithm ref erring the imited system resource. It obtains the pref erab e ba ance between security and using resource.
