Adi Shamir is the Borman Professor of Computer Science at the Weizmann Institute in Israel. Shamir specializes in cryptographic schemes and protocols, with special emphasis on cryptanalysis. He co-developed the RSA cryptosystem with Rivest and Adleman; introduced the notion of secret sharing; broke the Merkle-Hellman knapsack-based cryptosystem; developed differential cryptanalysis with Biham; proposed the notion of identity-based cryptography; developed the Fiat-Shamir identification and signature schemes; and showed (with Tromer) how to use new side channel attacks, such as cache attacks and acoustic attacks to break numerous cryptosystems.
