The discovery of differential cryptanalysis is generally attributed to [[Eli Biham]] and [[Adi Shamir]] in the late 1980s, who published a number of attacks against various block ciphers and hash functions, including a theoretical weakness in the [[Data Encryption Standard]] (DES). It was noted by Biham and Shamir that DES was surprisingly resistant to differential cryptanalysis, but small modifications to the algorithm would make it much more susceptible.<ref name = "Biham_1993">{{cite book | vauthors = Biham E, Shamir A |title=Differential cryptanalysis of the data encryption standard |date=1993 |publisher=Springer Verlag |location=New York |isbn=978-0-387-97930-4}} | The public discovery and disclosure of differential cryptanalysis is generally attributed to [[Eli Biham]] and [[Adi Shamir]] in the late 1980s, who published a number of attacks against various block ciphers and hash functions, including a theoretical weakness in the [[Data Encryption Standard]] (DES).
