The Super Audio CD crypto algorithm needs two keys for descrambling: 1. The PSP-PDM key that is hidden in the disc; and 2. The “Initial Values”, a key that is hidden in the IC (integrated circuit). The value of these keys is not available outside a single IC and is not transmitted between IC’s. http://sonicstudio.net/pdf/dsd/SACD_TechOverview.pdf
Content encryption. DSD data is encyrpted with an 80-bit key on the disc. The key is never transmitted on any bus, or anywhere outside the proprietary SACD chipset. SACD’s encryption and decryption are available only in carefully licensed and controlled hardware. http://web.archive.org/web/20071011020215/www.smr-home-theatre.org/surround2002/technology/page_09.shtml "carefully licensed and controlled hardware" -- mortslim ------------------------------------------------------------------------ mortslim's Profile: http://forums.slimdevices.com/member.php?userid=11039 View this thread: http://forums.slimdevices.com/showthread.php?t=74688 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
