Karol Budzyn

Cryptography Researcher · Post-Quantum & Quantum-Safe Systems · Warsaw, PL

Student at Warsaw University of Technology (ARICS — Automation, Robotics & Industrial Computer Science), with a research focus on Post-Quantum Cryptography (PQC) and Zero-Knowledge Proof systems (ZKP). Particularly interested in ZK-SNARKs, ZK-STARKs, and lattice-based cryptographic constructions in the context of critical infrastructure.

My engineering background includes commissioning industrial control systems and integrating secure communication protocols — experience that now feeds directly into my research on cryptographic agility: migrating legacy communication layers toward quantum-resistant primitives.

From programming ATEX-rated PLCs in explosive atmospheres to designing encrypted middleware for governmental data exchange — I build systems where correctness and security are non-negotiable.
