When the National Bureau of Standards (NBS) was tasked with developing a commercial encryption standard, they asked for help from NSA. This talk will discuss the development of the Data Encryption Standard (DES), and the politics that played a major role in the process. The IBM algorithm and the changes NSA made to that algorithm will be discussed, as will the rationale behind those changes. The talk will highlight academic response to DES and the open analytic work culminating in the Shamir and Biham attack on DES.
