Typical AE schemes are supposed to be secure when used as specified. However, they can – and often do – fail miserably when used improperly. As a partial remedy, Rogaway and Shrimpton proposed (nonce-)misuse-resistant AE (MRAE) and the first MRAE scheme SIV (“Synthetic Initialization Vector”). This paper proposesRIV(“Robust Initialization Vector”), which extends the generic SIV construction by an additional call to the internal PRF.RIVinherits the full security assurance from SIV, but unlike SIV and other MRAE schemes,RIVis also provably secure when releasing unverified plaintexts. This follows a recent line of research on“Robust Authenticated Encryption”, similar to the CAESAR candidate AEZ.An AES-based instantiation ofRIVruns at less than 1.5 cpb on current x64 processors. Unlike the proposed instantiation of AEZ, which gains speed by relying on reduced-round AES, our instantiation ofRIVis provably secure under the single assumption of the AES being secure.
