Don Coppersmith (born c. 1950) is a cryptographer and mathematician. 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.He also improved the quantum Fourier transform discovered by Peter Shor in the same year (1994). 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. Don is also a co-designer of the SEAL and Scream ciphers.

Coppersmith studierte am Massachusetts Institute of Technology mit dem Bachelor-Abschluss in Mathematik 1972 und an der Harvard University, an der er 1975 seinen Master-Abschluss erhielt und 1977 bei Shlomo Sternberg promoviert wurde (Deformation of Lie groups and Lie algebras). Als Student war er von 1968 bis 1971 viermal hintereinander Sieger im Putnam-Wettbewerb und damit Putnam Fellow. Er forschte seit 1977 bei IBM und war an der Fortentwicklung des Data Encryption Standard beteiligt, insbesondere der Kryptanalyse der S-Boxen und deren Verbesserung gegen Differentielle Kryptanalyse.
