Root of Trust Components to Increase Security of RISC-V Based Systems on Chips

Aportación a congreso RISC-V Summit 2023This work presents the design and validation of a compact and efficient RO-PUF/TRNG module, which combines ID generation and entropy source functionalities, and can be used as an essential primitive of a hardware RoT for RISC-V based SoCs. The design was encapsulated as an IP core to provide it with a high level of configurability, flexibility, and reusability. A comprehensive SDK for online characterization, validation, and performance monitoring of PUF and TRNG quality metrics was also developed. The experimental results show that the proposed RO-PUF/TRNG IP is suitable for increasing the security of IoT applications.This research was supported in part by the SPIRS Project with Grant Agreement No. 952622 under the EU H2020 research and innovation programme M.C.M.R. holds a postdoc fellowship from the Andalusia Government with support from PO FSE of EU.Peer reviewe
