Undeterred by Blu-ray hacks, Sony unveils yet another cipher for DRM

CLEFIA is aimed at portable electronics and home entertainment products, and can be applied to music, images, or even video. The big claim from Sony is that CLEFIA has "sufficient immunity against known cryptanalytic attacks," yet it has relatively low hardware requirements. The company plans to formally present the CLEFIA algorithm at the Fast Software Encryption 2007 conference in Luxembourg.
