ciphertext overhead to reach a level of
√
n. While this enables only 2 genera-
tions of pirate evolution and may still be acceptable given the high capacity
of Blu-ray disks it shows that the benefits of the subset difference method
(its low ciphertext overhead) are entirely cancelled in practice due to pirate
evolution. Going beyond, the concept of pirate evolution inspired new types
of attack scenarios as the ones introduced by Billet and Phan in [

].
