Do You Think AES is a Secure Cipher ?
There is no weakness whatsoever in Rijndael.
No plausible method for cracking AES is at sight.
Applicability of algebraic attacks to AES is uncertain.
These attacks will remain slower than exhaustive key search.
Whatever happens, AES should be replaced by a better cipher.
An attack faster than brute force will emerge.
AES will be broken in practice by 2030.
AES will already be cracked before 2010.
The NSA can probably already crack it.
