Abstract
A method for generating data encryption coding with variable clocking according to one embodiment includes storing a secret code in a first register; storing a locally-generated random number in a second register; storing a second random number generated at a remote device in the second register; extracting bits from the first register; extracting bits from the second register; setting a state of a clock generator in response to one or more bits from each register, the clock generator generating a clock signal controlling operation of the first register, the clock signal varying depending on the state of the clock generator.
