Embodiment Construction

[0016] The invention will be further described in detail with reference to the following specific embodiments and accompanying drawings. Except for the content specifically mentioned below, the process, conditions, experimental methods, etc. for implementing the present invention are all common knowledge and common knowledge in the field, and the present invention is not particularly limited.

[0017] figure 1 As shown in , a zero-day vulnerability-based approach to assessing the expected functional safety hazards of autonomous driving is divided into five steps. Step 1: Analyze the expected functional safety system, and create hazards based on a zero-day vulnerability-based attack graph for a specific scenario. Graph model HG; Step 2: Find all scenarios sc in turn based on the hazard graph model HG 0 ,sc 1 ,…,sc nhazard path. The hazard path is considered to be established only after the reachability verification. The hazard path is composed of a series of known and unkno...

Abstract

The invention provides an automatic driving expected function safety hazard assessment method based on zero-day loopholes, which comprises the following four steps of: 1, determining a zero-day vulnerability hazard map model of an expected function safety system; 2, simplifying a zero-day vulnerability model of the expected function security system, and constructing a hazard path threatening the expected function security; 3, respectively calculating hazard values SK and SUK of a known trigger event and an unknown trigger event through a calculation program based on the hazard path; and 4, calculating an expected function safety system safety value svs based on the dynamic weight scheme. Hazard assessment of expected function safety and zero-day vulnerability safety assessment are combined, a solution for improving the expected function safety is invented based on an information safety solution, and the expected function safety hazard detection rate of an advanced driving assistance system and an automatic driving system is improved.

Description

technical field [0001] The invention relates to the safety field of automatic driving technology and advanced assisted driving technology, in particular to a method for evaluating the safety hazards of expected functions of automatic driving based on zero-day vulnerabilities. Background technique [0002] In recent years, the development of autonomous driving technology and advanced driver assistance systems has brought huge social benefits to road vehicles. With the development of advanced driver assistance systems in autonomous driving technology, the safety requirements for road vehicles are becoming more and more comprehensive and specific. The acceptable level of safety for road vehicles should meet the expected functional safety in addition to information safety and functional safety. ISO defines safety of intended functionality (SOTIF) in the ISO 21448 standard as the absence of an unreasonable risk of a hazard arising from an insufficiency of the intended function o...
