US 7475259 B1Abstract
One or more embodiments of the invention provide a method, apparatus, and article of manufacture for preventing unauthorized access to digital services comprising. Access control to digital services is distributed among a plurality of physically separate and independently controlled nonvolatile memory components on a system bus. The plurality of nonvolatile memory components are then communicatively coupled to a microprocessor. The microprocessor is configured to use state information in the nonvolatile memory components to provide desired functionality and enforce one or more security policies for accessing the digital services.
U.S. patent application Ser. No. 10/085,920, entitled “DEDICATED NONVOLATILE MEMORY”, by Ronald Cocchi, et al., filed on the same date herewith;
U.S. patent application Ser. No. 10/085,346, entitled “HIDDEN IDENTIFICATION”, by Ronald Cocchi, et al., filed on the same date herewith; and
U.S. patent application Ser. No. 10,085,860, entitled “ASYNCHRONOUS CONFIGURATION”, by Ronald Cocchi, et. al, filed on the same date herewith.
Digital service systems often contain a security component known as a smart card that prevents unauthorized access to the digital services. The smart card contains a microprocessor, memory components, a custom logic block, and a system input/output module. The security system may be compromised if components are attacked or used in unintended ways.
A CAM 512 often contains a microprocessor, memory components (a volatile component and a nonvolatile component) and a system input/output module to communicate with transport 508. Traditional microprocessors within a CAM 512 have nonvolatile memory to contain state that is used to provide the desired functionality and enforce security policies intended by the designers. The microprocessor and/or memory access control unit restricts access to the memory components.
