- Protecting against power analysis on block cipher implementations is no longer optional but mandatory. One of the most well-known techniques to prevent power analysis is higherorder masking which randomizes sensitive intermediate values by using masks picked randomly for each execution of cryptographic algorithms. Because of its slow performance however, we need to find a more simple way. In this paper, we present a new method for achieving this goal. In the presence of deceiving runs of encryption using several false keys, we aim to disturb power analysis. Our experiment finds out how many false keys are required to disturb power analysis.
