My proposed talk I would like to discuss the advancement of Quantum computing and how that affects our current crypto levels. Has AES 256 finally met its match? It is my belief that most IT security professionals work with crypto everyday but very few know how it works, what it does, when to use AES over 3DES etc. This talk will discuss the everyday uses of cryptography for example, You are setting up a new 802.11 network and you need to decide what mode AES to use. I will discuss the modes and why you should or should not use ECB ever! If you only need to decrypt, is it ok to just use OFB/CFB? I will also discuss the choices we are presented with in creating new SSL Certificates; Should you choose AES or Diffie-Hellman? My goal is to present real world scenarios where IT pros and security professionals are presented with every day and give easy to understand explanations on how to assess risk and make educated decisions on what the proper key exchange should be.
