New Attacks against AES-256

[I)ruid]

Paper and details are not yet public, but Schneier provides a summary:

Basically, if AES-256 is implemented with fewer rounds than the standard
specifies (essentially the number of rounds recommended for AES-128), it
is susceptible to a number of related-key attacks.
