嵌入式系统安全问题解决方案综述

摘要

Most embedded systems have high security and reliability requirements.At the same time,their hardware resources are usually limited.The processing capability of their CPUs and internal storage space are both inferior to general computer systems.This makes the design and solving of security problem for embedded systems face great challenges.This paper firstly concretely analyses security requirements from different objects and different aspects,and then does some research on embedded frame structures based on security framework.At last,the paper introduces two security technologies for embedded systems which are relatively commonly used at present.%嵌入式系统大多具有较高的安全性和可靠性要求,但与此同时,其硬件资源往往相对有限,CPU的处理能力、内部存储空间均比通用计算机系统有明显差距.这使得嵌入式系统的安全性设计和解决方案面临很大的挑战.首先针对不同对象从不同层面具体分析了嵌入式系统的安全性需求,然后对基于安全构架的嵌入式结构体系做了较深入的研究,最后介绍了两种当今比较常用的提升嵌入式系统安全性的技术.
