Abstract
A randomization element includes a logic input for inputting a logic signal, a logic output for outputting the input logic signal at a delay and a randomization element. The randomization elements introduces the delay between said logic input and said logic output and operates selectably in static mode and in dynamic mode in accordance with a mode control signal. A logic circuit may be formed with randomization elements interspersed amongst the logic gates, to obtain protection against side channel attacks by inputting a selected control sequence into the randomization elements.
