Abstract
Systems, devices and/or methods that facilitate mutual authentication for processor and memory pairing are presented. A processor and a suitably equipped memory can be provided with a shared secret to facilitate mutual authentication. In addition, the memory can be configured to verify that the system operating instructions have not been subjected to unauthorized alterations. System integrity can be ensured according to the disclosed subject matter by mutual authentication of the processor and memory and verification of the authenticity of system operating instructions at or near each system power up. As a result, the disclosed subject matter can facilitate relatively low complexity assurance of system integrity as a replacement or supplement to conventional techniques.
