Abstract

The Data Encryption Standard (DES) describes a venerable symmetric key cryptographic algorithm initially standardized by the National Bureau of Standards in 1976. DES, although initially controversial, has been ubiquitously deployed in civilian security applications, serving as the international lingua franca for cryptography. Recently, the National Institute of Standards and Technology concluded the standardization process for the algorithm that will supplant DES, the Advanced Encryption Standard. This talk will compare and contrast these two standards.
