Standing the Test of Time: The Data Encryption Standard
Susan Landau
The Data Encryption Standard is the most widely used public cryptosystem in the world. Successfully used for more than twenty years, it has only recently begun to be vulnerable to the power of present-day computers. Landau describes the principles behind this encryption system and the kinds of attacks that are used on it.
