Improved authentication method in embedded networks systems. An autonomous vehicle approach
By adding connectivity to in-vehicle networks (including multimedia devices) and external networks (e.g. wireless and Internet) the attack surface was dramatically extended. In this context, there are several types of attacks already been demonstrated on automotive/AV control networks using compromised network connection or physical manipulation. Subsequently, the success attacks violate safety requirements, being able to disrupt system operation or even to take over operational control. In order to avoid false authentication or identity theft of devices or IoT, this paper proposes a time-based authentication method. The proposed method increases the degree of cybersecurity and allows its implementation on independent, low power mobile devices. Finally, a critical conclusion regarding the proposed authentication methods is presented.
