Estudio y Evaluación de Ataques a una Red Simulada de Sensores Vehiculares basada en Tecnología CAN, empleando el Vehicle Network Toolbox de MATLAB.

Abstract

This work focuses on the study and the evaluation of attacks on a simulated sensor network based on the CAN protocol by using the Vehicle Network Toolbox from MATLAB. The increasing integration of electronics devices in moderns vehicles has improved their efficiency and safety, but it has also introduced vulnerabilities in their communication that can be exploited by malicious attackers. In particular, the CAN protocol, widely used in intra-vehicular communication, presents weaknesses in terms of integrity, confidentiality and availability, making it susceptible to attacks such as communication interception, data injection and denial of service. In this study, two critical vehicular systems are simulated: the anti-lock system (ABS) and the keyless ignition system; both implemented in MATLAB/Simulink using CAN communication by means of the Vehicle Network Toolbox. Subsequently, two types of attacks are simulated: a denial-of-service (DoS) attack on the ABS system and a data injection attack on the ignition system. The obtained results allow for an evaluation of the impact of these attacks on the normal operation of the systems and provide relevant conclusions about the vulnerabilities of the CAN protocol and the importance of implementing security measures in modern vehicles.
