Abstract
Official abstract text for this publication.
Aspects of a method and system for multi-level security initialization and configuration are provided. A security system may comprise a security processor, a host processor, and at least one security component, such as a descrambler. The security processor may enable a security component based on information stored within a non-volatile memory integrated within the security processor. The host processor may enable generation of at least one configuration command communicated to the security processor for configuring the enabled security component. The configuration command may correspond to a security control operational mode for the security component that may indicate, for example, activation or deactivation of the security component. The security processor may authenticate a digital signature in the configuration command. Initialization and configuration may be performed during a system boot sequence of the security system.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for system initialization, the method comprising: enabling a security component in a security system based on a value of an enable bit stored within a non-volatile memory integrated within a security processor in said security system; and activating, by said security processor, said security component in response to a configuration command communicated to said security processor by a host processor in said security system if said security componen…
