Oh, okay, my mind is set on remote attacks. In the scenario where the
attacker has access to the hardware under attack, doing fake
computations most resembling normal computations is definitely better
then clock. In general, access to the hardware raises the bar for
security very high. In such a scenario assembly language might be the
best choice, or at least analysis of the binary code.
