Hardware and software developers must be granted least-privileged and just-in-time access without dependencies on the network and cloud infrastructure. The zero-trust blueprint proposes that automakers and suppliers prioritize addressing digital identity, the hardware-based root of trust (RoT), and explicit cryptography-based authentication and authorization of all interactions, including app-level micro-segmentation. Whether a hacker takes over a driver assistance function, tampers with a software update, or exploits software vulnerabilities of keyless entry, the number of malicious attacks will only rise. Indeed, software-based features and services are projected to be a $640 billion market by 2031, growing from about 9%, or $181 billion, of OEMs’ current annual revenue to 22%, according to Capgemini Research Institute.Īs vehicle software content and connected services grow, so does code complexity and the need for the entire automotive ecosystem to grapple with a new set of risks. There is a customer expectation that a vehicle’s capabilities can be updated over the air with a centralized electric/electronic (E/E) architecture that will redefine today’s release cycles. High-performance computing (HPC) and in-vehicle networks have become central to all aspects of the driving experience, from body control, driver assistance, infotainment, and powertrain systems. Today’s vehicles are more software than metal.
