One aspect of differential cryptanalysis that appears to have been largely overlooked is the use of several differences to attack a cipher simultaneously. While the use of quartets and octets have been briefly described by Biham and Shamir [1], this was not carried to its logical conclusion — namely, how many different attacks can you use and still get an improvement. The issues involved are briefly covered here.
