The document discusses security issues with automotive systems as they transition to multi-core embedded systems with more connectivity. It notes existing security vulnerabilities and risks that multi-core architectures could exacerbate if not properly addressed. However, it also outlines opportunities for multi-cores to enhance attack tolerance and enable self-monitoring. Key research challenges include developing secure architectures with hardware trust anchors and secure elements, as well as secure software through techniques like sandboxing and attestation. Secure multi-cores could be an enabling technology for cyber-physical systems if these open challenges are addressed.
