Johannes Buchmann

Johannes Alfred Buchmann (born November 20, 1953, in

Johannes Buchmann studied mathematics, physics, pedagogy and philosophy at the University of Cologne from 1974 to 1979 after graduating from high school in 1972 and completing his military service. After passing the first state examination for teaching at grammar schools in 1979, he taught mathematics at a Cologne secondary school from 1980 to 1983 while at the same time working as a research assistant at the university. In 1982 he did his doctorate at the university under the supervision of Hans-Joachim Stender. In 1984 he passed the second state examination. In 1985/86 he was with Hans Zassenhaus at Ohio State University on a scholarship from the Alexander von Humboldt Foundation. From 1986 to 1988 he was research assistant of Michael Pohst at the University of Düsseldorf, where he habilitated in 1988. Then he worked as professor of computer science at Saarland University. In 1996, he then was professor of computer science and mathematics at the Technische Universität Darmstadt. He retired in 2019.^[1]

From 2001 to 2007, he was vice president for Research at the

From 2017 to 2018, Johannes Buchmann trained as an MBSR (Mindfulness-Based Stress Reduction) teacher at the Institute for Mindfulness. Since then he has been working as a certified MBSR teacher.^[3]

Buchmann is married and has two sons.

Buchmann's achievements include scientific essays on algorithms in

Since 1996, Buchmann has been working intensively on the topic of public key infrastructures, for which he published the book Introduction to Public Key Infrastructures together with Evangelos Karatsiolis and Alexander Wiesmaier in 2013.^[6] Buchmann has been working on post-quantum cryptography since 2003 and published a book of the same name together with Daniel J. Bernstein and Erik Dahmen in 2009.^[7] Buchmann is also the author of the textbook Introduction to Cryptography, which has been translated into seven languages.^[8]

In Saarbrücken, the research work of Buchmann concentrated on the theoretical cryptography and cryptanalysis of number theory-based public-key methods like RSA. During his time in Saarbrücken, Buchmann also founded the

In 2018, the stateful hash-based signature scheme XMSS developed by a team of researchers under the direction of Buchmann became the first international standard for post-quantum signature schemes. XMSS is the first future-proof secure and practical signature scheme with minimal security requirements. The work began in 2003.^{[10][11][12][13]}
