New AES crypto standard broken already?
Theoretical attacks against AES (Advanced Encryption Standard) winner Rijndael and runner-up Serpent have been published. They might work in the practical world; they might not.

Now while this represents an interesting bit of research, it does not mean that AES has been or even can be cracked in the real world.
