We examine the IND-qCPA security of the widespread block cipher modes of operation CBC, CFB, OFB, CTR, and XTS (i.e., security against quantum adversaries doing queries in superposition). We show that OFB and CTR are secure assuming that the underlying block cipher is a standard secure PRF (a pseudorandom function secure under classical queries). We give(More)
