Abstract

See full text

A digital cable network architecture includes hosts that include a receiver with a hash function generator that calculates hash values based on a hash function and data from memory blocks in the receiver. A policy file store contains policy files having a service provider section, a consumer section, and/or a manufacturer section that can be updated by the service provider, a consumer and/or a receiver manufacturer. A service provider downloads monitor applications (MAs) and policy files to the hosts over the cable medium. The MAs access the service provider section, the consumer section, and/or the manufacturer section of the policy file to alter resource contention, service provisioning, and/or alter fraudulent receiver identification calculations. The hash function of the receiver outputs the hash values to the MA, which compares the hash values to expected hash values to identify fraudulent access.
