Yvo G. Desmedt (b. 1956) is the 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]
