摘要: 嵌入式系统的安全问题日益凸显,为此,提出一种嵌入式系统可生存性分析模型。借鉴近年来国内外研究成果,给出嵌入式系统可生存性的形式化定义,建立系统威胁、系统可生存性需求、系统可生存性策略3个子模型对嵌入式系统可生存性进行分析,形成一套系统可生存性分析的一般流程。实例分析表明,该模型能定量评估嵌入式系统的可生存性,并通过评估结果得到影响系统可生存性的主要因素。

Abstract: Aiming at the more and more obvious security problems of embedded systems, this paper puts forward a model for embedded system survivability analysis. Based on the analysis of the research results of survivability at home and abroad in recent years, it proposes a formalized definition of embedded system survivability, establishes three submodels of system threats, system survivability requirements and strategies, and thus forms a set of general process on systematic survivability analysis. Analysis results show that this model can assess quantitively embedded system survivability effectively and analyze major factors influencing system survivability by assessment results.

Key words: embedded system, survivability, embedded system threat, survivability strategy, survivability assessment
