RISC-V Summit

Version 1.0.0 of the RISC-V Vector Cryptography extensions specification was ratified in late 2023 and adds high-performance cryptography operations to the comprehensive list of ISA features that RISC-V officially supports. We present the first open-source implementation of the RISC-V Vector Cryptography specification, using the PULP Project's Ara vector processor as a baseline and targeting a 28nm technology node. We present the design/verification opportunities and challenges that were encountered. Furthermore, a detailed review of the implementation and benchmarking results will be included in the presentation.
