X-Original-To: cryptography@metzdowd.com X-Original-To: cryptography@metzdowd.com Date: Thu, 30 Sep 2004 21:07:10 +1200 From: Nicolai Moles-Benfell <nmol010@ec.auckland.ac.nz> To: cryptography@metzdowd.com In-Reply-To: <E1CB4i7-0005sA-00@medusa01> Hi, A number of sources state that the NSA changed the S-Boxes (and reduced the key size) of IBM's original DES submission, and that these change were made to strengthen the cipher against differential/linear/?? cryptanalysis. Does anybody have a reference to, or have an electronic copy of these original S-Boxes? Nicolai.
