Abstract
The present disclosure relates to a method for authenticating instructions and operands in an electronic system comprising a controller. The method includes extracting instructions and operands via a first circuit of the controller from at least a first memory internal to the controller using a matrix bus of the controller, collecting, on the matrix bus, via a second circuit internal to the controller, instructions and operands during their transmission to the first circuit, and generating a word representative of the instructions and operands.
