When the National Bureau of Standards (NBS) was tasked with developing a commercial encryption standard, they asked for help from the National Security Agency (NSA). Join Richard M. (Dickie) George, the Senior Advisor for Cyber Security at the Applied Physics Lab, to discuss the development of the Data Encryption Standard (DES), and the politics that played a major role in the process. Learn about the IBM algorithm and the changes NSA made to that algorithm, as well as the rationale behind those changes. Dickie George will also highlight academic response to DES and the open analytic work culminating in the Shamir and Biham attack on DES.
