Abstract
A method and system of protecting content by ensuring a secure boot of a processor environment. A processor is coupled to a certification unit which may include a decryption engine and a one-way hash unit. The certification unit is employed to ensure that only certified software is permitted access to memory containing content and that only certified software may access a content bit stream such as may flow across a 1394 serial bus from a digital video disk player. By preventing access by uncertified software, the risk of a personal computer being used as an instrumentality of piracy is reduced.
