嵌入式系统安全体系结构研究

Study on secure architecture of embedded system

对嵌入式系统的安全需求、安全挑战、面临的攻击进行了研究,分析了几种典型的嵌入式安全体系结构,在此基础上提出了一个带有网络功能的嵌入式系统安全体系结构的三维框架。该框架将安全从概念设计阶段就作为嵌入式系统设计的一个要素,将安全集成到嵌入式系统的每一个抽象层,在嵌入式系统设计的整个阶段加以考虑,按该框架设计的嵌入式系统能够减少安全漏洞,在面积、能量、计算能力受限的情况下最大化嵌入式系统安全。

Based the study in several kind oftypical embedded security architecture, a three dimensional framework ofsecure embedded system architecture with networks is proposed, after the security requirements, security challenges and the attacks of the embedded system has been analyzed. The security was been designed as an important elements from the conceptual phase, was been integrated into the every abstract layer of the embedded system, and was been considered in the entire design phases of the embedded system. According to this framework, embedded security design can expect reducing the risk ofsecurity flaws, letting designers maximize security while limiting area, energy and computation costs,
