GCM-SIV1.5: Optimal Tradeoff between GCM-SIV1 and GCM-SIV2

open access: yesEntropy, 2023
GCM-SIV2 is a nonce-based beyond-birthday-bound (BBB)-secure authenticated encryption (AE) mode introduced by Iwata and Minematsu at FSE 2017. However, it is built by combining two instances of GCM-SIV1 and needs eight keys, which increases the costs of ...
