Quantum Half and Full Spinning Operator-Based Nonlinear Confusion Component
IEEE Access, 2021 The structure of a substitution box (S-box) is one of the principal ideas of the modern encryption techniques. The security of a modern encryption algorithm highly depends on its nonlinear confusion component.

Dumbo, Jumbo, and Delirium: Parallel Authenticated Encryption for the Lightweight Circus
IACR Transactions on Symmetric Cryptology, 2020 With the trend to connect more and more devices to the Internet, authenticated encryption has become a major backbone in securing the communication, not only between these devices and servers, but also the direct communication among these devices.

Indifferentiable Authenticated Encryption [PDF]
, 2018 We study Authenticated Encryption with Associated Data (AEAD) from the viewpoint of composition in arbitrary (single-stage) environments. We use the indifferentiability framework to formalize the intuition that a "good" AEAD scheme should have random ciphertexts subject to de-cryptability.

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.

Authenticated On-Line Encryption [PDF]
, 2004 In this paper, we investigate the authenticated encryption paradigm, and its security against blockwise adaptive adversaries, mounting chosen ciphertext attacks on on-the-fly cryptographic devices. We remark that most of the existing solutions are insecure in this context, since they provide a decryption oracle for any ciphertext.

Fast Encryption and Authentication: XCBC Encryption and XECB Authentication Modes [PDF]
, 2002 We present the eXtended Ciphertext Block Chaining (XCBC) and the eXtended Electronic Codebook (XECB) encryption schemes or modes of encryption that can detect encrypted-message forgeries with high probability even when used with typical noncryptographic Manipulation Detection Code (MDC) functions (e.g., bitwise exclusive-or and cyclic redundancy code ...

The State of the Authenticated Encryption [PDF]
Tatra Mountains Mathematical Publications, 2016 AbstractEnsuring confidentiality and integrity of communication remains among the most important goals of cryptography. The notion of authenticated encryption marries these two security goals in a single symmetric-key, cryptographic primitive. A lot of effort has been invested in authenticated encryption during the fifteen years of its existence.
