Edna Grossman

Edna K. Grossman (* as Edna Kalka in Germany ) is an American cryptologist and mathematician who did research for IBM.

Grossman studied at Brooklyn College and Mathematics was founded in 1972 by Wilhelm Magnus doctorate at New York University ( Courant Institute ) (The automorphism group of finitely generated free groups). It belonged in the 1970s to a team of mathematicians at the Thomas J. Watson Research Center, which focused on cryptography ( including Horst Feistel, Don Coppersmith, Roy Adler, Bryant Tuckerman and Alan Konheim ). From the work of the Data Encryption Standard ( DES) was established based on the Lucifer cipher of Feistel.

They also analyzed the security of the DES and related cryptosystems and in a Technical Report for IBM 1977 with Bryant Tuckerman (Analysis of a Feistel -like cipher Weakened by having no rotating key), they developed what against later in the 1990s as a Slide Attack block ciphers became acquainted with several rounds.

In the 1990s, she worked at IBM in data mining applications.
