Markku-Juhani O. Saarinen


I’m a cryptographer – a person who professionally builds and breaks cryptosystems. Here’s a recent CV with a clickable list of publications.

In September 2018 I joined PQShield Ltd., a new spin-out of the University of Oxford Mathematical Institute, focusing on Post-Quantum Cryptography. I work on various things but I’m mainly responsible for cryptographic hardware IP and the PQSoC Post-Quantum Secure Element.

Current Public Research (2020)

LWAES ISA is a lightweight RISC-V instruction set extension proposal for AES and SM4 block ciphers – a contribution to the RISC-V Foundation. A short report: A Lightweight ISA Extension for AES and SM4.

PQPS is a “lab” for power measurements of PQ crypto – basic research for mobile and IoT security. There’s a brief write-up on this on arXiv now: Mobile Energy Requirements of the Upcoming NIST Post-Quantum Cryptography Standards.

ROUND5 is a merger of my Hila5 first-round proposal with Round2 (mainly from Philips), and an official candidate in the second round of the NIST Post-Quantum Cryptography Project.

R5EMBED is a highly portable, self-contained, lightweight implementation of the Round5 post-quantum cryptographic algorithms.
