Advances in Hardware Security

The field of hardware security is moving towards innovative solutions to counter side-channel attacks and information leaks. Researchers are exploring new approaches to secure prefetching mechanisms, such as obfuscating sensitive load effects, and developing scalable methods for verifying hardware-software contracts. Additionally, there is a growing interest in automated hardware trojan insertion and simulation-based fault injection to stress-test detection tools and assess circuit vulnerability. These advancements have the potential to significantly improve the security of modern processors and industrial-scale designs. Noteworthy papers include: PhantomFetch, which presents a hardware-agnostic defense against prefetcher side-channel attacks, and Coverage-Guided Pre-Silicon Fuzzing, which introduces a novel approach to verifying hardware-software contracts. FsimNNs is also notable for its open-source platform for SEU simulation-based fault injection using graph neural networks.
