Analysis on Attack Scenarios and Countermeasures for Self-driving Car and Its Infrastructures

Abstract

Autonomous vehicles collect and process information required for driving autonomously and apply the processed result for vehicle driving thereby driving vehicles automatically by identifying road situations without additional control of brakes, handling, and acceleration pedal by drivers. Since self-driving cars collect information from various sensors and communication is done between various sensors and devices over the infrastructure, they are vulnerable to unexpected accidents due to malicious hacking attacks if self-driving cars are commercialized without ensuring security technologies and establishment of security systems. In particular, securing safety is highly emphasized due to automobile technology that is directly related to human lives and safety. In the present paper, security threats against self-driving cars and infrastructures are analyzed and possible attack scenarios are developed to predict the impact. Furthermore, the current status on research and development of security technology is analyzed and items of technology development to ensure cyber security of self-driving cars and infrastructures as well as R&D strategies are presented for future research.
