On Impossible and Truncated Distinguishers for IoT-Friendly AEAD Algorithms
IEEE Internet of Things JournalIn this article, we propose a methodology for finding impossible differential distinguishers for permutations used in sponge-like constructions. Given the difference between the typical block ciphers and such permutations in terms of key additions, we ...

We present the Deoxys family of authenticated encryption schemes, which consists of Deoxys-I and Deoxys-II. Both are nonce-based authenticated encryption schemes with associated data and have either 128- or 256-bit keys. Deoxys-I is similar to OCB: It is single-pass but insecure when nonces are repeated; in contrast, Deoxys-II is nonce-misuse resistant.

An AEAD Variant of the Grain Stream Cipher
Lecture Notes in Computer Science, 2019A new Grain stream cipher, denoted Grain-128AEAD is presented, with support for authenticated encryption with associated data. The cipher takes a 128-bit key and a 96-bit IV and produces a pseudo random sequence that is used for encryption and authentication of messages.

Random-Access AEAD for Fast Lightweight Online Encryption [PDF]
IACR Cryptology ePrint ArchiveWe study the problem of random-access authenticated encryption. In this setting, one wishes to encrypt (resp., decrypt) a large payload in an online matter, i.e., using a limited amount of memory, while allowing for the processing of plaintext (resp ...

$\mathsf{sMGM}$: parameterizable AEAD mode
Математические вопросы криптографии, 2023В работе представлен новый режим аутентифицированного шифрования $\mathsf{sMGM}$ (strong Multilinear Galois Mode). Предлагаемая конструкция может рассматриваться как расширение стандартизированного режима $\mathsf{MGM}$ и его модификации $\mathsf{MGM2}$, представленной на конференции CTCrypt'21.

ON THE SECURITY OF AEAD-CRYPTOSYSTEM OF THE GCM TYPE [PDF]
Prikladnaya Diskretnaya Matematika, 2016 Summary: A provable security methodology for the cryptosystems ensuring information privacy and authenticity is discussed. A simplified version of the well-known estimates for the provable security of the AEAD-cryptosystem GCM with an initialization vector of fixed length is proposed.

The THFC Scheme for compactly committing AEAD
2021 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2021In order to overcome some disadvantages of the Encryptment scheme, that is, its hidden compression function should be a secure pseudo-random function to resist relevant key attacks: for key K, the adversary can arbitrarily select X and inquire K⊕X. Therefore, the new scheme of adding tweakable block cipher (TBC) in the paper makes it more resistant to ...

A Hardware-Efficient AEAD Stream Cipher Based on a Hybrid Nonlinear Feedback Register Structure
Computer Science Symposium in RussiaIn this paper, we propose the hybrid register stream cipher, a hardware-oriented AEAD-capable stream cipher based on nonlinear feedback shift registers (NLFSRs) and Composite Mersenne Product Registers (CMPRs) designed to balance security and hardware ...
