Data transmission in automotive applications and security/safety requirements

Abstract

Radio communications have a fundamental importance for assuring data exchange between vehicles and from infrastructures to vehicles, or vice-versa. With reference to assisted driving and even completely autonomous driving, such communications must satisfy very high degree of security, with the goal of assuring also the safety of drivers and passengers. Two frameworks are expected to provide a support for secure data transmissions: 5G technology and wireless V2X protocols. Interoperability between them and a proper interface with automotive buses are recommended, in order to reach the best performance and to decrease the costs. In this respect, an efficient use of channel coding can guarantee error correction, i.e., reliable communication, and also strong resilience against cyber attacks.
