Method and apparatus to achieve data pointer obfuscation for content protection of streaming media DMA engines

摘要

Embodiments include a system for obfuscating the location of protected data in the memory of a computer system. The system provides a protected mode supported by a memory controller that does not allow the address relating to the location of protected data to be read or accessed. This system may be used to prevent the piracy of data temporarily stored in an unencrypted state in system memory.
