Summary
🤩
Rockstar🎓
Top SchoolSimon Masson is a cryptography engineer with nine years of research and applied experience focused on post-quantum signatures and blockchain security. He holds a PhD in cryptography and progressed from academic work at Thales into zero-knowledge protocol research at Heliax and now implements cryptographic primitives for blockchain applications at ZKNOX. Simon combines deep mathematical training—an agrégation in mathematics and a research master in applied algebra—with hands-on experience optimizing elliptic-curve operations and developing protocol-grade cryptography. Comfortable bridging theory and production, he brings rare expertise in both post-quantum signature design and practical implementation for decentralized systems.
