The Quest to Build Trust Earlier in Digital Design

Abstract

The ever-rising complexity of computer systems presents challenges for maintaining security and trust throughout their lifetime. As hardware forms the foundation of a secure system, we need tools and techniques that support computer hardware engineers to improve trust and help them address security concerns. This paper highlights a vision for tools and techniques to enhance the security of digital hardware in earlier stages of the digital design process, especially during design with hardware description languages. We discuss the challenges that design teams face and explore some recent literature on understanding, identifying, and mitigating hardware security weaknesses as early as possible. We highlight the opportunities that emerge with open-source hardware development and sketch some open questions that guide ongoing research in this domain.
