The metadata subpage is missing. You can start it via filling in this form or by following the instructions that come up after clicking on the [show] link to the right.

Do you see this on PREVIEW? then SAVE! before following a link. To find out more about the use of metadata for the management of Citizendium pages, see CZ:Metadata. You may see this box for one of two reasons. Either: A - New page has been created, or subpages template was added to an existing page B - Cluster move is in progress Click either the A or B link for further instructions. [Feel free to recommend improvements to the text or links in this template] A - For a New Cluster use the following directions Subpages format requires a metadata page. Using the following instructions will complete the process of creating this article's subpages. Click the blue "metadata template" link below to create the page. On the edit page that appears paste in the article's title across from "pagename =". You might also fill out the checklist part of the form. Ignore the rest. For background, see Using the Subpages template Don't worry--you'll get the hang of it right away. Remember to hit Save! the "metadata template". However, you can create articles without subpages. Just delete the {{subpages}} template from the top of this page and this prompt will disappear. :) Don't feel obligated to use subpages, it's more important that you write sentences, which you can always do without writing fancy code. [Feel free to recommend improvements to the text or links in this template] B - For a Cluster Move use the following directions The metadata template should be moved to the new name as the first step. Please revert this move and start by using the Move Cluster link at the top left of the talk page. The name prior to this move can be found at the following link.

The AES competition involved many of the world's top cryptographers.

Some of the major developments in cryptography before AES were:

• DES from an IBM team that included Don Coppersmith
• Differential cryptanalysis, discovered by Coppersmith et al, but kept secret at NSA request. Re-discovered and first published in open literature by Eli Biham and Adi Shamir.
• Linear cryptanalysis, from Mitsuru Matsui.
• The RSA algorithm for public key cryptography, from Ron Rivest, Adi Shamir and Leonard Adleman.

Both differential and linear cryptanalysis break DES with less effort than brute force, but at least two writers have proposed methods of making ciphers provably resistant to linear and differential cryptanalysis, Carlisle Adams in CAST and Serge Vaudenay with his decorrelation theory.

Standard references in the field include Bruce Schneier's Applied Cryptography and Ross Anderson's Security Engineering .

A direct ancestor of Rijndael, the winning AES candidate, was Square, designed by Joan Daemen and Vincent Rijmen. Lars Knudsen invented a new attack, integral cryptanalysis, to break it. Knudsen also broke ancestors of other AES candidates, including the first versions of both SAFER and LOKI. Later versions of all these ciphers were strengthened against those attacks.

Most of the people mentioned above, and a number of others well-known in the field, participated in the AES process.

Here is a table showing some of the major players. For several papers, some of the co-authors are omitted to make the table more readable; see references in the main article for complete co-author lists.
