You asked for it. For me, doing useless computations just to make sure the timing is right, does not make sense. Using a clock makes sense. If you believe that is the case, how are you planning to tackle power analysis attacks? (Note that such attacks are not just theoretical.)

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.
