Much like DES was broken for years, but never truly released to the public until quite some time later. I know that AES was more open to the public when it was initially developed, and many proposed models were rejected. However, could it be broken somehow, but not announced to the public. Or is it used by too many companies, that as soon as AES would break, it would make news?

for clarification: I am talking about the Rijndael cypher, which was adopted by the US government.

"Is it possible that there is something that we don't know about?" There is really no possible way this can be answered sensibly. – AviD♦ Mar 14 at 13:40
fair enough. Is there any public researchon potential weaknesses about the cypher? – marcwho Mar 14 at 13:43

Ah, that's a much better question. However, I would recommend asking that over on Cryptography, instead of here. – AviD♦ Mar 14 at 13:47

The cryptoanalytic breaks against DES are minor. DES biggest weakness was know from day 1 (and deliberate): it uses a 56 bit key. – CodesInChaos Mar 14 at 15:31
