Automotive: asvin offers innovative CSMS update monitoring for the entire software supply chain
The set of regulations developed by the Inland Transport Committee of the UNECE (United Nations Economic Commission for Europe) poses extreme challenges for the automotive industry:
If manufacturers and suppliers fail to integrate comprehensive management systems for cybersecurity in vehicles by 2022, the industry faces an estimated loss of one billion euros. Stuttgart-based start-up asvin has developed a modular solution that provides key building blocks for cybersecurity systems. These include documentation and verification of software as well as verification of firmware within the supply chain from the OEM to the vehicle.
To ensure that autonomous driving does not become a nightmare due to hacker attacks, according to UNECE WP 29 (United Nations World Forum for Harmonization of Vehicle Regulations), cybersecurity is to be included as an integral part of type approval from 2022. In addition to establishing a legal framework for OTA updates, the regulations require manufacturers to introduce a cyber security management system (CSMS) in the vehicle. From 2024, the regulation will apply to all new registrations.
Building CSMS on a modular basis
“Despite the long lead time, it is to be feared that vehicle manufacturers will not manage to develop and deploy appropriate all-encompassing systems by next year,” explains Dr. Klaus Schaaf, former head of the Cali- fornia Electronics Research Lab and of “Wireless Wolfsburg” at Volkswagen AG and now a consultant for auto- motive mobility and edge technologies. “Currently, there are no systems that can both address ever-changing security requirements and ensure compatibility of legacy systems. In order to design fully functional cybersecurity systems, it is important to, both CSMS and SUMS (Software Update Management Systems) to be modular and to generate corresponding system modules that meet the industry standard.”
The Stuttgart-based cybersecurity experts at asvin have developed such a module, which makes it possible to track and document the integrity and security status of software throughout the production process and operation on the vehicle. The solution allows, for example, the exact inventory of installed software to be collected for each vehicle and the path of the software from the supplier to the vehicle to be monitored in a process-safe manner. This makes it possible to detect manipulations of the software in the entire process chain, and the software inventory can be compared with known vulnerabilities in risk monitoring for each vehicle. The system from the Stuttgart-based cybersecurity professionals also uses decentralized consensus mechanisms and smart contracts to protect information from manipulation and provide rules in the software supply chain for automations, such as over-the-air updates.
