摘要
目前,舰载移动式指挥平台及可视化维修终端对系统安全性需求日益加大。为了满足该需求,文章首先阐述了当前国产移动处理器现状、可信移动计算平台的相关概念,分析了北斗定位技术在军事领域的应用前景;然后围绕龙芯1A国产处理器设计支持GPS导航定位的可信移动计算机软硬件架构,并对其进行了安全性分析,从而为提高龙芯1A移动计算机的安全性、数据保密性和可用性提供了一种软硬件解决方案。
Nowadays,the ship-borne mobile commanding platform and visualized maintenance terminal have an increasing demand of system security enhancement.In order to meet this demand,this paper firstly introduces the current development situation of domestic mobile processor,the background information of trusted mobile computing platform,and the prospect of the ＂Beidou＂ positioning technology application in the military field.Then,based on Godson 1A processor and GPS navigation positioning technology,one trusted mobile computing architecture is designed.Finally,formal security analysis is carried out and the results show that system integrity,data security and availability are well kept in the architecture.
