Don Coppersmith is a cryptographer and mathematician. Cryptography (or cryptology; from Greek grc κρυπτός kryptos, "hidden secret" and grc γράφω gráphō, "I write" A mathematician is a person whose primary area of study and research is the field of Mathematics. He was involved in the design of the Data Encryption Standard block cipher at IBM, particularly the design of the S-boxes, strengthening them against differential cryptanalysis. The Data Encryption Standard ( DES) is a Cipher (a method for Encrypting information selected by NBS as an official Federal Information In Cryptography, a block cipher is a symmetric key Cipher which operates on fixed-length groups of Bits termed blocks, with an International Business Machines Corporation abbreviated IBM and nicknamed "Big Blue", is a multinational Computer Technology Differential cryptanalysis is a general form of Cryptanalysis applicable primarily to Block ciphers but also to Stream ciphers and Cryptographic hash [1] He has also worked on algorithms for computing discrete logarithms, the cryptanalysis of RSA, methods for rapid matrix multiplication (see Coppersmith-Winograd algorithm) and IBM's MARS cipher. In Mathematics, Computing, Linguistics and related subjects an algorithm is a sequence of finite instructions often used for Calculation In Mathematics, specifically in Abstract algebra and its applications discrete logarithms are group-theoretic analogues of ordinary Logarithms Cryptanalysis (from the Greek kryptós, "hidden" and analýein, "to loosen" or "to untie" is the study of methods for In Cryptography, RSA is an Algorithm for Public-key cryptography. In Mathematics, matrix multiplication is the operation of multiplying a matrix with either a scalar or another matrix In the mathematical discipline of Linear algebra, the Coppersmith–Winograd algorithm, named after Don Coppersmith and Shmuel Winograd, is the In Cryptography, MARS is a Block cipher that was IBM 's submission to the Advanced Encryption Standard process. Don is also a codesigner of the SEAL and Scream ciphers. In Cryptography, SEAL (Software-Optimized Encryption Algorithm is a very fast Stream cipher optimised for machines with a 32- Bit Word size The Scream cipher is a word-based Stream cipher developed by Shai Halevi, Don Coppersmith and Charanjit Jutla from IBM.
In 1972, Coppersmith obtained a Bachelor's degree in mathematics at the Massachusetts Institute of Technology, and a Masters and PhD in mathematics from Harvard University in 1975 and 1977 respectively. Mathematics is the body of Knowledge and Academic discipline that studies such concepts as Quantity, Structure, Space and [1] He was a Putnam Fellow each year from 1968–1971, becoming the first four-time Putnam Fellow in history. The William Lowell Putnam Mathematical Competition, often abbreviated to the Putnam Competition, is an annual mathematics competition for Undergraduate In 1998, he started Ponder This, an online monthly column on mathematical puzzles and problems. This article is about puzzles that require mathematics in order to solve them In October 2005, the column was taken over by James Shearer. [2]
In 2002, Coppersmith won the RSA Security Award for Mathematics. [3]
Coppersmith is currently employed at the Center for Communications Research in Princeton, a division of the Institute for Defense Analyses. The Institute for Defense Analyses (IDA is a non-profit corporation that administers three Federally funded research and development centers (FFRDCs to assist the United States
