AES

Researchers at a K.U.Leuven university in Belgium have identified flaws in AES, the encryption algorithm used by hundreds of millions users worldwide securing everything from ecommerce transactions using SSL to file encyrption tools including the popular BitLocker on PCs and FileVault on Mac OS X.

Researchers Andrey Bogdanov, Dmitry Khovratovich and Christian Rechberger came up with a clever new attack that can recover the secret key four times easier then previously thought.
