Ivan Bjerre Damgård (born 1956) is a Danish cryptographer and currently a professor at the Department of Computer Science, Aarhus University, Denmark.

Academic background

In 1983, he obtained a master's degree in mathematics (with minors in music and computer science) at Aarhus University. He began his PhD studies in 1985 at the same university, and was for a period a guest researcher at CWI in Amsterdam in 1987.[1] He earned his PhD degree in May, 1988, with the thesis Ubetinget beskyttelse i kryptografiske protokoller (Unconditional protection in cryptographic protocols) and has been employed at Aarhus University ever since. Damgård became full professor in 2005.[2]

Research

Damgård co-invented the Merkle–Damgård construction, which is used in influential cryptographic hash functions such as SHA-2, SHA-1 and MD5. He discovered the structure independently of Ralph Merkle and published it in 1989.[3]

Ivan Damgård is one of the founders of the Cryptomathic company. In 2010, he was selected as IACR Fellow.[4]

In 2020, he received the Public Key Cryptography (PKC) conference Test of Time Award for the paper "A Generalisation, a Simplification and Some Applications of Paillier's Probabilistic Public-Key System", which was published in PKC 2001 by Damgård and Jurik.[5]

In 2021, Damgård received the ACM Symposium on Theory of Computing (STOC) Test of Time Award[6] for the paper "Multiparty unconditionally secure protocols", which was published in STOC 1988 by Chaum, Crépeau, and Damgård.

O exame ao sinal de Lasègue ajuda a diagnosticar causas de lombalgia. Sinal de Lasègue é um sinal clínico que descreve a existência de dor na parte posterior da perna quando a perna é estendida. A dor é provocada pela flexão da coxa sobre a bacia. Este sinal é característico da ciática, mas pode ser observado em mais condições e ajuda a determinar se um paciente com lombalgia tem uma hérnia discal.[1] O sinal foi descrito por Ernest-Charles Lasègue em 1864.
