We show the applicability of Simon’s period finding quantum algorithm to the cryptanalysis of several tweakable enciphering schemes (TESs), namely,
CMC, EME, XCB, TET and FAST.
For XCB, TET and FAST, the attacks reveal portions of the secret key. For all of the five TESs, we show distinguishing attacks based on two
encryption queries.
