Abstract
A highly configurable kernel supports a wide variety of content protection systems. The kernel may reside in a host that interacts with a secure processor maintaining content protection clients. After establishing communication with the secure processor, the host receives messages from content protection clients requesting rules for message handling operations to support client operations. This flexible configuration allows for dynamic reconfiguration of host and secure processor operation.
