Abstract: accounting. OCB uses + 2 block-cipher calls to encrypt a nonempty message M . (The empty string takes three block-cipher calls.) We compare this with CBC encryption and CBC encryption plus a CBC MAC. Namely, "basic" CBC encryption, where one assumes a random IV and a message which is a multiple of the block length, uses |M |/n block-cipher calls. (A more fair comparison uses some padding regime and sets IV = EK # (N ), so both schemes use a nonce IV). If one combines basic CBC encryption... (Update)
