Abstract

The invention relates to a method for obtaining a universal security demand of embedded software. The method comprises the steps of obtaining static structure elements and dynamic running structure elements of the embedded software according to a static modeling mechanism and a dynamic modeling mechanism respectively; obtaining failure modes of the static structure elements and the dynamic runningstructure elements; setting security measures for the failure modes, and obtaining the universal security demand; and tailoring the universal security demand. According to the method, the comprehensiveness and expansibility of obtaining the universal demand of the embedded software can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of software security development, in particular to a method for acquiring general security requirements of embedded software. Background technique [0002] With the widespread application of embedded software in safety-critical fields, such as military, nuclear energy, aviation, aerospace, medical, automobile and other fields, software safety has become a research hotspot. A large number of studies have shown that most of the failures and failures (especially those that violate safety) come from the omission or misunderstanding of requirements. Likewise, Leveson's research shows that in space engineering, a considerable number of software-related failures are related to flawed requirements or misunderstood software goals. As the software development lifecycle progresses, the cost of correcting software glitches and errors increases significantly. [0003] The beginning and key of the entire software securi...
