Cryptography Myths and Misconceptions

Tony Ropson

Abstract:

This talk is intended to address some of the more common cryptography myths and misconceptions that appear in online cryptography discussion groups.  “Is AES-128 ECB mode broken?”, “Should I encrypt everything twice to be extra secure?”, “Has the government broken all of our crypto?”  We will take a look at some of these questions and provide a better understanding of how cryptography is less “magic” and more of a deep and fascinating area of information security.
