Abstract: Random delays are commonly used as a countermeasure to inhibit side channel analysis and fault attacks in embedded devices. This paper proposes a different manner of generating random delays. The alternative proposed increases the desynchronisation compared to uniformly distributed random delays. It is also shown that it is possible to reduce the amount of time lost due to random delays, while maintaining the increased variation.
