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. To date, Sony has revealed that the technology is "a 128-bit block encryption that supports key lengths of 128, 192 or 256 bits." They also say that CLEFIA is powerful enough to defend the digital media against "known cryptoanalytic attacks."
Sony hopes that the technology will make its way into software and AV devices in the future and they claim that CLEFIA can offer stronger security while requiring fewer operations during encoding and decoding processes. The whole process would reduce strain on hardware and can lead to smaller and better AV devices in the future. The company also revealed that the technology "achieves a maximum data bandwidth of 1.42 Gb/s in 90 nm CMOS cell libraries, which would be efficient enough to bring CLEFIA to smartcard environments."
More news will be posted on the technology as it becomes available.
