Title:
Quantum Key Search with Side Channel Advice
Authors: Daniel P. Martin, Ashley Montanaro, Elisabeth Oswald, Dan Shepherd
Abstract:Recently, a number of results have been published that show how to combine classical cryptanalysis with quantum algorithms, thereby (potentially) achieving considerable speed-ups. We follow this trend but add a novel twist by considering how to utilise side channel leakage in a quantum setting. We show how to `rewrite’ an existing algorithm for computing the rank of a key after a side channel attack, such that it results in an enumeration algorithm that produces batches of keys that can be tested using Grover’s algorithm. This results in the first quantum key search that benefits from side channel information.
