Development of a novel automotive cybersecurity, integrity level, framework

Abstract

As automated driver assistance functions are getting more and more popular, they will surly have a significant impact on our life especially considering security and the expected serious effects of malicious interventions. In light of the introduced aspects, the Test Field of Zalaegerszeg has started a research to evaluate the required professional and scientific framework to prevent transport systems from malicious external intervention. With regard to this aspect, the homologation system has been analyzed. In accordance with this the main objective of the article is to develop integrity level structure related to transport systems especially focusing on security issues. In this context the paper reconsiders the structure of ASIL to provide a proper framework focusing on the outstandingly important issues of cybersecurity. To develop a novel SIL framework a tailor-made method is identified to define risk parameter values related to certain SIL categories. At the end of the research, the investigation has determined the acceptable hazard rates related to the S&SIL architecture.
