Peter Schwabe is a researcher in applied cryptography working at Radboud University Nijmegen in the Netherlands. He is mainly working on secure and efficient software implementations of cryptography and occasionally cryptanalysis. Examples of what he's been working on includes speed-record-setting timing-attack protected software for AES-CTR and AES-GCM, the Ed25519 signature scheme, and recently the formal verification of a hand-optimized assembly implementation of Curve25519 Diffie-Hellman key exchange. He is in the core development team of NaCl, the only cryptographic library that systematically protects against timing attacks.
