Dr. Markku-Juhani O. Saarinen Cryptographer and Security Engineer

Professional

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.

Current Research Interests

Focus of my current research is in quantum resistant cryptography and next-generation lighweight symmetric ciphers.

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

SNEIK is a family of lightweight (embedded, low power) cryptographic algorithms and my proposal for the NIST Lightweight Cryptography Project.

R5EMBED is a highly portable, self-contained, lightweight implementation of the Round5 post-quantum cryptographic algorithms. It also includes the R5SNEIK variant that gains significant performance and size advantages on lightweight platforms by leveraging the SNEIK primitives (above).
