There are some nice benefits to this competition: it is inclusive (of both new algorithm designs and new mode designs) and it focuses attention on the important real-world issue of AE. I am hoping to see developments that both perform well and improve robustness (e.g. against misuse). I also hope to see a healthy discussion about requirements; people with use cases should provide them as input. David On 1/15/13 9:52 AM, "D. J.

Adding a clean, well documented reference implementation that uses std types (stdint.h) is makes it even better and if you also include internal states during processing of at least one test vector you make the implementers life _much_ easier. The siphash specification includes good test vectors and a great walk through that made the implementation pretty comfortable. The C reference code is, shall we say, terse. Also it really helps if one defines operation symbols before using them in the spec... https://131002.net/siphash/ -- Med vänlig hälsning, Yours Joachim Strömbergson - Alltid i harmonisk svängning. ======================================================================== From sfluhrer@cisco.com Fri Jan 25 07:55:08 2013 Return-Path: X-Original-To: cfrg@ietfa.amsl.com Delivered-To: cfrg@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 8ABEB21F889A for ;

Today at the MIT Media Lab Legal Hack-a-thon on Identity we had a great presentation from a couple of designers from the NSA regarding their new lightweight ciphers called SIMON and SPECK. These ciphers are designed for low-power limited gate devices (such as RFID and similar devices).
