Edna Grossman
Edna K. Grossman (* as Edna Kalka in Germany ) is an American cryptologist and mathematician who did research for IBM .
Grossman studied mathematics at Brooklyn College and received his doctorate in 1972 under Wilhelm Magnus at New York University (Courant Institute) ( The automorphism group of finitely generated free groups ). She was part of a team of mathematicians at the Thomas J. Watson Research Center who studied cryptography (including Horst Feistel , Don Coppersmith , Roy Adler, Bryant Tuckerman, and Alan Konheim ) in the 1970s . The Data Encryption Standard (DES) based on the Lucifer cipher from Feistel emerged from this work.
They also analyzed the security of DES and related cryptosystems and in a 1977 technical report for IBM with Bryant Tuckerman (Analysis of a Feistel-like cipher weakened by having no rotating key) they developed what was later called a Slide Attack against in the 1990s Block ciphers with several rounds became known.
In the 1990s she worked on data mining applications at IBM.
