[[Image:adishamir2003.jpg|thumb|right|300px|Adi Shamir at the CRYPTO 2003 conference.]] Adi Shamir (born 1952) is an Israeli cryptography. He was one of the inventors of the RSA algorithm (along with Ron Rivest and Len Adleman), and has made numerous contributions to the fields of cryptography and computer science. ==Education== Born in Tel-Aviv, Shamir received a BS in Mathematics from Tel-Aviv University in 1973 and obtained his MSc and PhD in Computer Science from the Weizmann Institute in 1975 and 1977 respectively. His thesis was titled, "Fixed Points of Recursive Programs". After a year postdoc at Warwick University, he did research at Massachusetts Institute of Technology from 1977–1980 before returning to be a member of the faculty of Mathematics and Computer Science of the Weizmann Institute. ==Research== 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 cryptosystem, visual cryptography, and the TWIRL and TWINKLE integer factorization 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 showing the equivalence of the computational complexity theory PSPACE and Interactive proof system. ==Awards== In recognition of his contributions to cryptography, Shamir was awarded, together with Ronald Rivest and Leonard Adleman, the 2002 Association for Computing Machinery Turing Award. Shamir has also received CM's Kannelakis Award, the Erdös Prize of the Israel Mathematical Society, the IEEE's W.R.G. Baker Prize, the UAP Scientific Prize, The Vatican's PIUS XI Gold Medal and the IEEE Koji Kobayashi Computers and Communications Award. ==See also== * List of important publications in computer science#Cryptography ==External links== * [http://www.informatik.uni-trier.de/~ley/db/indices/a-tree/s/Shamir:Adi.html Adi Shamir's publications] 1952 births Modern cryptographers Israeli mathematicians 20th century mathematicians 21st century mathematicians Israeli computer scientists Turing Award laureates
I would like to point out that Sean Murphy did not invented differential cryptanalysis. (Comment insert by Orr Dunkelman, Computer Science Dept.

(As an aside, I'm pretty sure you "invent" an algorithm such as Rijndael, and that you "discover" weaknesses in ciphers (e.g. "Biham invented a differential weakness in DES" sounds wrong...).
