Abstract
The Data Encryption Standard (DES) is the most widely used symmetric key cryptosystem in the commercial world. DES was published in 1975 by the National Bureau of Standards, and since then it and its variants have been commonly used. DES is utilized in many modern industries and products including the Blackberry, electronic financial transactions, and access cards to corporate offices. An efficient but secure cryptosystem is challenging to produce and even after it has been deemed “secure” new attacks and vulnerabilities are often discovered. By investigating the algebraic structure of a simplified version of DES we are able to analyze the structure and security of DES used in the commercial world in an attempt to improve and understand its current security and potential threats.
