The [[Block_cipher#The_AES_generation | AES competition]] involved many of the world's top cryptographers.

Some of the major developments in [[cryptography]] before AES were:
* [[Block_cipher#DES|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]].

At least two writers have proposed methods of making ciphers provably resistant to linear and differential cryptanalysis, [[Carlisle Adams]] in [[Block_cipher#CAST|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'' <ref>{{cite book|author=Ross Anderson|title=Security Engineering|url=http://www.cl.cam.ac.uk/~rja14/book.html}}</ref>. At the time of the AES competition, the best online index of current research was the [http://www2.mat.dtu.dk/people/Lars.R.Knudsen/aes.html Block Cipher Lounge] maintained by [[Lars Knudsen]] and [[Vincent Rijmen]].

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.

Quite a few of these people are also well-known for breaking ciphers or other security systems. Perhaps the best-publicised break was Wagner and Ian Goldberg cracking [[Netscape]]'s [[SSL]] via flaws in the [[random number]] generator. Anderson or his students break almost every [[smartcard]] that comes on the market. Knudsen, Biham, Schneier and Kelsey have all published many papers on [[cryptanalysis]] of various ciphers. Some of the others have various breaks to their credit as well.
