Abstract:
Safety is the primary requirement and the key challenge in autonomous vehicles. Any accidental failures (safety issue) and/or intentional attacks (security issue) may result in severe injury or loss of life. Thus, any missing consideration on either failures or attacks may lead to terrible consequence. Safety and security are inter-related and, therefore, have to be aligned early in the development process. International standards, International Organization for Standardization (ISO 26262), and Society of Automotive Engineers (SAE J3061), have been proposed for vehicle safety and security. However, they do not address all the aspects of autonomous vehicles as they rely on a human driver controlling the vehicle. In high automation vehicles (level 3 or above, as defined by the international standard SAE J3016), the autonomous driving system is fully responsible for driving the vehicle. Thus, different driving automation levels have to be taken into consideration when designing autonomous vehicle safety and security. We propose an approach for aligning safety and security lifecycles, based on SAE J3061, SAE J3016, and ISO 26262 standards at an early development phase. The proposed approach uses the Failure, Attack and Countermeasure (FACT) graph to connect safety failures, security attacks, and the associated countermeasures. The proposed approach is helpful for designing or tailoring the safety and security processes, and selecting appropriate countermeasures for autonomous vehicles taking into consideration the driving automation levels.
