US~2: An Unified Safety and Security Analysis Method for Autonomous Vehicles

摘要

Autonomous Vehicles (AVs) are security-critical systems, and safety is primary goal for AVs. The high degree of integration between safety and security introduces new problem: how to systematically analyse safety and security? In this paper, we propose an Unified Safety and Security analysis method (US~2), which uses a simple quantification scheme to assess safety hazards and security threats simultaneously. US~2 is a useful tool for safety and security requirements specification and selection of countermeasures. Example of US~2 application is included to highlight the strengths of the proposed method.
