Yvo G. Desmedt (born 1956) is the Jonsson Distinguished Professor at the University of Texas at Dallas, and in addition Chair of Information Communication Technology at University College London. He was a pioneer of threshold cryptography[1] and is an International Association for Cryptologic Research Fellow. He also made crucial observations that were used in the cryptanalysis of the Merkle–Hellman knapsack cryptosystem[2] and observed properties of the Data Encryption Standard which were used by Eli Biham and Adi Shamir when they invented Differential Cryptanalysis.[3]
