The automotive industry continues to be a hotbed of patent innovation. The automotive industry is innovating in vehicle controller area network (CAN) security due to the increasing complexity of networks, increasing cyberattacks, and increasing awareness of the importance of security. Trends include intrusion detection and prevention systems, encryption, authentication, and access control. The availability of affordable sensors and processors, growing demand for connected vehicles, and increased awareness of the risks of theft and hacking are driving these developments. These technologies aim to protect vehicles from theft and provide peace of mind for vehicle owners. Vehicle CAN security technologies include intrusion detection and prevention systems (IDPS), encryption, authentication, and access control. IDPS systems detect and prevent intrusions using techniques such as anomaly detection and protocol analysis. Encryption protects CAN messages’ confidentiality and prevents unauthorized modifications. Authentication verifies device identity and restricts message types. Emerging technologies include artificial intelligence (AI) and machine learning (ML) for advanced IDPS systems, blockchain for tamper-proof record-keeping, and vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication for comprehensive network security. As these technologies continue to develop, vehicle CAN security is expected to improve. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Cybersecurity in automotive: vehicle CAN securityBuy the report here.
