APPARATUS AND METHOD FOR IMPROVING SECURITY OF A BUS-BASED SYSTEM THROUGH COMMUNICATION ARCHITECTURE ENHANCEMENTS

摘要

A security policy associated with a system is evaluated. The system includes a communication bus having a data bus and a plurality of components interconnected via the communication bus. The system also includes a circuit configured to evaluate a security policy associated with the system by reading at least one data bus signal associated with a transaction between at least two of the plurality of components.
