Abstract
A runtime classifier hardware circuit is incorporated into an electronic device for implementing hardware security by storing a support vector model in memory which is derived from pre-silicon verification data to define secure behavior for a first circuit on the electronic device; monitoring input and/or output signals associated with the first circuit using the runtime classifier hardware circuit which compares the input and/or output signals to the support vector model to detect an outlier input signal and/or outlier output signal for the first circuit; and blocking the outlier input and/or output signal from being input to or output from the first circuit.
