Development of the First Open-Source Implementation of the RISC-V Vector Cryptography Extension

on YouTube ↗23m

" summary

Marian is the first open‑source implementation of the RISC‑V Vector Cryptography extension built on the PULP Ara2 core and validated on UltraScale FPGA with AES‑GCM and SM3 functional end‑to‑end tests. Implementation uses 128/256‑bit element groups, handles ELEN mismatches by trapping, and uses a simple non‑pipelined operand collection across four lanes. Synthesis estimate shows ~100,000 gates (≈6% of core) and microbenchmarks report about 10x faster than OpenSSL for AES workloads; source and paper are on GitHub and ACM CCS.
