Secure boot verifies the integrity and authenticity of code before execution; otherwise, it terminates the boot process. In contrast, measured boot produces verifiable evidence of code integrity at boot time, for example using the Device Identifier Composition Engine (DICE). However, in both mechanisms, hashing large code is the main performance bottleneck. This work combines secure boot and DICE-based measured boot, implements the design on a CVA6-based RISC-V platform, incorporates post-quantum cryptography for quantum-resistant secure boot, and accelerates computationally intensive hash computations through a custom Keccak hardware accelerator.
