The Future of Automotive Security Automotive by Editorial Team - March 29, 2023March 29, 20230 As vehicles become increasingly connected, automakers must consider cybersecurity concerns. Hackers may exploit weaknesses in V2V communications protocols or the devices themselves to gain access to sensitive data and information. The future of automotive security is an ever-evolving field. As the number of vehicles on the road continues to increase, so does the potential for theft and other threats to vehicle safety. To ensure that your car is as safe as possible, it’s important to stay up-to-date on security technologies and best practices. Cyberattacks can also lead to vehicle theft. For example, hackers could steal key fobs and use them to unlock cars without the owner’s knowledge. Security challenges As digital innovations continue to transform the automotive industry, the threat landscape is changing. The increasing complexity of the vehicles’ electronic systems, communication networks, control algorithms, software and users present new security risks. Today’s vehicle electronics are increasingly vulnerable to cyber-attacks and data hacks that can harm humans, property and brand reputations. This is in part due to the complex supply chain for automotive electronics, which relies on hundreds of independent vendors. These vendors are often not equipped to handle cybersecurity risks. Consequently, the automotive industry is under pressure to provide protection against these threats. It needs to do more than patch its devices. It must ensure that the devices are authenticated, that they have limited access to vehicle systems and that they communicate with each other securely. This could involve a combination of hardware, software and firmware solutions. Key management Key management is a way to track who is using your keys, how often they are used, and why. You can also create policies to ensure you’re securing your data, complying with industry standards, and protecting your reputation. Automotive supply chains pose a number of unique key management challenges. For instance, a supplier like GM may need to distribute cryptographic keys from many different vehicle manufacturers. This makes it difficult for a supplier to manage these keys across the entire supply chain, as each manufacturer has a separate process for creating them. This is why it is crucial to adopt a common key management system for the entire industry. This will ensure security, reduce complexity, and save time and money for automakers. Asymmetric encryption Asymmetric encryption, which relies on two keys – one encrypts, and the other decodes – provides a stronger level of security. The process begins with an algorithm that generates a key pair mathematically, using a public and private key. The sender uses a public key to encrypt the message, and the recipient uses a private key to unscramble it. Asymmetric encryption is an excellent way to protect sensitive information from cybercriminals. Despite its many advantages, asymmetric encryption requires a lot of storage and processing power. This can be a problem if the number of vehicles in a network is growing rapidly, or if group broadcasting is used. To counter this issue, researchers developed a cryptographic scheme that decreases the key cardinality by sharing an asymmetric key among a group of vehicles. This results in a more economical system that still maintains the principles of asymmetric encryption. Simulations show that group broadcasting is a highly efficient solution to enhance VANET security, by decreasing the number of messages exchanged between vehicles. Device attestation Device attestation, also called hardware-based key attestation, is a security feature that gives you confidence that your keys are stored in a device’s hardware-backed keystore. It can also help prevent tampering. When a device is factory-programmed, the manufacturer injects a hardware-backed keystore into the device’s boot process. The device then uses a secure boot mechanism to ensure that this keystore is available when needed. Then, the device’s Trusted Authority (TA) compiles measurements into an Attestation Result and sends it to the Samsung Attestation Server using TLS encryption. The server validates the Attestation Result to make sure that it was generated on Samsung hardware and by the TA, then signs the Attestation Result with a key that can be verified using the Samsung Root Certificate. The resulting attestation certificate includes the key identifier of the device, its creator and owner custom extensions and other measurements that reflect its mode of operation. The attestation certificate can then be used to verify the properties of hardware-backed keys and verify that they’re compatible with other devices. As the automotive industry becomes increasingly reliant on technology, the need for skilled technicians who understand the intricacies of automotive security has become more important than ever. That’s why it’s worth recognizing the “Technician of the Month” program, which celebrates the best and brightest in the automotive industry. These technicians are instrumental in ensuring that vehicles are safe from cyberattacks, and their contributions will continue to be vital as the industry moves forward. The future of automotive security relies on these technicians to stay up-to-date on the latest threats and technological advancements, and the “Technician of the Month” program is an excellent way to recognize and encourage their dedication to their craft.
