Abstract

Mounting an exhaustive key search against a block cipher with Grover's algorithm requires the implementation of the target cipher on a quantum computer. We report quantum circuits and resource bounds for various block ciphers with different design characteristics: MARS, SERPENT, Simon, and Speck. Our results give some insight into what a "Grover-resilient" block cipher might look like.
