Adi Shamir (Hebrew: עדי שמיר; born July 6, 1952) is an Israeli cryptographer. He is a co-inventor of the RSA algorithm (along with Ron Rivest and Len Adleman), a co-inventor of the Feige–Fiat–Shamir identification scheme (along with Uriel Feige and Amos Fiat), one of the inventors of differential cryptanalysis and has made numerous contributions to the fields of cryptography and computer science.
Born in Tel Aviv, Shamir received a BSc degree in mathematics from Tel Aviv University in 1973 and obtained his MSc and PhD degrees in Computer Science from the Weizmann Institute in 1975 and 1977 respectively. His thesis was titled, "Fixed Points of Recursive Programs and their Relation in Differential Agard Calculus". After a year postdoc at University of Warwick, he did research at MIT from 1977–1980 before returning to be a member of the faculty of Mathematics and Computer Science at the Weizmann Institute. Starting from 2006, he is also an invited professor at École Normale Supérieure in Paris.
In addition to RSA, Shamir's other numerous inventions and contributions to cryptography include the Shamir secret sharing scheme, the breaking of the Merkle-Hellman knapsack cryptosystem, visual cryptography, and the TWIRL and TWINKLE factoring devices. Together with Eli Biham, he discovered differential cryptanalysis, a general method for attacking block ciphers. It later emerged that differential cryptanalysis was already known — and kept a secret — by both IBM and the NSA.
Shamir has also made contributions to computer science outside of cryptography, such as finding the first linear time algorithm for 2-satisfiability and showing the equivalence of the complexity classes PSPACE and IP.
Shamir has received a number of awards, including the following:
- the 2002 ACM Turing Award, together with Rivest and Adleman, in recognition of his contributions to cryptography
- the Paris Kanellakis Theory and Practice Award;
- the Erdős Prize of the Israel Mathematical Society,
- the 1986 IEEE W.R.G. Baker Award
- the UAP Scientific Prize;
- The Vatican's PIUS XI Gold Medal;
- the 2000 IEEE Koji Kobayashi Computers and Communications Award
- the Israel Prize, in 2008, for computer sciences.
- an honorary DMath (Doctor of Mathematics) degree from the University of Waterloo
- 2017 (33rd) Japan Prize in the field of Electronics, Information and Communication for his contribution to information security through pioneering research on cryptography
