Abstract
A random slip generator is provided to lessen side channel leakage and thus thwart cryptanalysis attacks, such as timing attacks and power analysis attacks. Random slip generation may be configurable so that the average frequency of random slips generated by the system may be set. Additional techniques are provided to make nullified instructions consume power like any other executing instruction.
