Tomáš Novák
Prague, Czech Republic
PhD in lattice-based cryptography and five years inside Czech national-security R&D. Tomáš leads our post-quantum work.
Tomáš spent eight years at Charles University in Prague — first finishing a PhD on lattice-based digital signatures, then teaching graduate seminars on the same. He left academia in 2019 for the Czech National Cyber and Information Security Agency (NÚKIB), where he spent five years on a team designing the cryptographic systems the Czech state will need when "harvest now, decrypt later" becomes a real adversary capability.
He joined Keltus because, as he likes to say, "papers are easy and deployments are hard." His specialty is taking newly standardized primitives — CRYSTALS-Dilithium, SPHINCS+, Kyber — and getting them into real software running on commodity hardware, without breaking the security proofs that make them worth using. He authored both of Keltus's SecureVote crypto subsystems and reviews every Keltus project that touches authentication or encryption.
Tomáš is also a published amateur historian — his 2022 essay on the Czechoslovak SIGINT effort during the Cold War got picked up by a national magazine. He plays squash three mornings a week, drinks coffee that he roasts himself, and is the only Keltus engineer who will openly defend the Oxford comma.
