Biography
Marc Stevens is a tenured researcher at the Cryptology Group at Centrum Wiskunde & Informatica in Amsterdam. He obtained his PhD in 2012 from the Mathematical Institute, Leiden University, for which he was awarded the KHMW (The Royal Holland Society of Sciences) Martinus van Marum prize. He is an expert in cryptanalysis, with emphasis on practical attacks on MD5 and SHA-1. Research highlights are the construction of the MD5 'rogue' Certification Authority (CRYPTO'09 Best Paper Award), the invention of counter-cryptanalysis and the reconstruction of the cryptanalytic attack in the supermalware Flame (CRYPTO'13 Best Young Researcher Paper Award), and the achievement of the first collision for full SHA-1 (CRYPTO'17 Best Paper Award & 2017 Pwnie Award for best cryptologic attack).Research
