She earned her M.S. in mathematics from New York University's Courant Institute of Mathematical Sciences, where she also received her Ph.D. in mathematics in 1972; her thesis, supervised by Wilhelm Magnus, concerned the symmetries of free groups.[1] Grossman worked for IBM, where she was part of the team that designed and analyzed the Data Encryption Standard.[2] She is known for her development, along with Bryant Tuckerman, of the first slide attack in cryptanalysis.[3]
