AEUR: authenticated encryption algorithm design based on uBlock round function
Tongxin xuebao, 2023 In order to improve the efficiency of the implementation of the authenticated encryption algorithm without compromising the security of the algorithm, a new authenticated encryption algorithm AEUR was designed.Firstly, based on the uBlock round function,

Authenticated encryption mode with blocks skipping
Системный анализ и прикладная информатика, 2021 Block symmetric ciphers are one of the most important components of modern information security systems. At the same time, in addition to the structure of the applied block symmetric cipher, the cryptographic strength and performance of the information ...

Linking Online Misuse-Resistant Authenticated Encryption and Blockwise Attack Models
IACR Transactions on Symmetric Cryptology, 2017 Real-world applications of authenticated encryption often require the encryption to be computable online, e.g. to compute the ith block of ciphertext after having processed the first i blocks of plaintext.

The Definition and Software Performance of Hashstream, a Fast Length-Flexible PRF
Cryptography, 2018 Two of the fastest types of cryptographic algorithms are the stream cipher and the almost-universal hash function. There are secure examples of each that process data in software using less than one CPU cycle per byte.

CMCC: Misuse Resistant Authenticated Encryption with Minimal Ciphertext Expansion
Cryptography, 2018 In some wireless environments, minimizing the size of messages is paramount due to the resulting significant energy savings. We present CMCC (CBC-MAC-CTR-CBC), an authenticated encryption scheme with associated data (AEAD) that is also nonce misuse ...

The Subterranean 2.0 Cipher Suite
IACR Transactions on Symmetric Cryptology, 2020 This paper presents the Subterranean 2.0 cipher suite that can be used for hashing, MAC computation, stream encryption and several types of authenticated encryption schemes. At its core it has a duplex object with a 257-bit state and a lightweight single-
