Patent abstract

A semiconductor integrated circuit includes a processor for executing application code from a memory and a verifier processor arranged to receive the application code via the same internal bus as the processor. The verifier processor performs a verification function to check that the application code is authentic. The verifier processor runs autonomously and cannot be spoofed as it receives the application code via the same internal bus as the main processor.
