A fundamental flaw in the ++AE authenticated encryption mode

Journal of Mathematical Cryptology, 2018
In this article, we analyse a block cipher mode of operation for authenticated encryption known as ++AE (plus-plus-AE). We show that this mode has a fundamental flaw: the scheme does not verify the most significant bit of any block in the plaintext ...

On the Quantum Security of OCB

IACR Transactions on Symmetric Cryptology, 2022
The OCB mode of operation for block ciphers has three variants, OCB1, OCB2 and OCB3. OCB1 and OCB3 can be used as secure authenticated encryption schemes whereas OCB2 has been shown to be classically insecure (Inoue et al., Crypto 2019).
