Sony reveals new DRM technology

Sony has announced that they have developed a new "block cipher algorithm" that is specifically designed to enable advanced copyright protection and authentication for distribution of digital media such as music, movies and images.

Sony says it plan to reveal more details about the technology, code named CLEFIA, at the Fast Software Encryption 2007 conference which begins on March 26 in Luxembourg.
