Johannes Buchmann

Johannes Alfred Buchmann (born November 20, 1953, in Cologne) is a German computer scientist, mathematician and professor emeritus at the department of computer science of the Technische Universität Darmstadt.

He is known for his research in algorithmic number theory, algebra, post-quantum cryptography and IT security. In 1993, he received the Gottfried Wilhelm Leibniz Prize together with Claus-Peter Schnorr for his work in algorithmic number theory and cryptography. Buchmann also developed the stateful hash-based signature scheme XMSS, the first future-proof secure and practical signature scheme with minimal security requirements, which was declared the first international standard for post-quantum signature schemes in 2018. In addition, he further developed IT security research in Germany. His efforts led to the creation of ATHENE, the largest research center for IT security in Europe. For this he received the Konrad Zuse Medal for Services to Computer Science of the Gesellschaft für Informatik (GI) in 2017. Provided by Wikipedia
