DYNAMIC SELECTION OF POWER ROUTES IN CIRCUITS

An apparatus is provided for varying paths from power sources to components in order to inhibit side channel attacks. The power source provides power. The circuit component consumes the power to perform a function and a power grid provides a plurality of redundant paths by which the power can flow from between the circuit component and one of a power source and ground, to perform the function. The power grid is dynamically selects at least one active path of the redundant paths through which the power flows to perform the function.
