Markku-Juhani O. Saarinen
Professional
I’m a cryptographer – one of those people who professionally build and sometimes break cryptosystems. Here’s a recent CV and a clickable list of publications.
I joined PQShield Ltd. in September 2018 as we were starting this University of Oxford spin-out where we build Post-Quantum Cryptography solutions.
Since January 2023, I have been a part-time Professor of Practice (työelämäprofessori, tietoturva) at Tampere University, associated with the Network and Information Security Group (NISEC).
PQCrypto 2024
I’m the Program Co-Chair (with Daniel Smith-Tone) of PQCrypto 2024, which will be held at the University of Oxford Mathematical Institute on June 12-14, 2024. We will post more details closer to the event.
