Acceleration of DICE Key Generation using Key Caching

Year: 2024

Type: conference-paper

Abstract: DICE is a Trusted Computing standard intended to secure resource-constrained off-the-shelf hardware. It implements a Root of Trust that can be used to construct a Chain of Trust boot system, with symmetric keys representing firmware integrity and device identity. Based on this, asymmetric keys can be generated, but this slows down the boot process significantly as the keys need to be generated on every boot. Asymmetric keys provide multiple advantages when compared to symmetric ones, especially for updateable systems. This prevents the adoption of DICE in fields with strict boot time requirements, for example in the automotive context.
