Generic Construction of Fully Anonymous Broadcast Authenticated Encryption with Keyword Search with Adaptive Corruptions

open access: yesIET Information Security, 2023
As a multireceiver variant of public key authenticated encryption with keyword search (PAEKS), broadcast authenticated encryption with keyword search (BAEKS) was proposed by Liu et al. (ACISP 2021).

Indifferentiable Authenticated Encryption [PDF]

open access: yes, 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

open access: yesTongxin 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

open access: yesСистемный 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 ...

Fast Encryption and Authentication: XCBC Encryption and XECB Authentication Modes [PDF]

open access: yes, 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 Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2020
The bit-sliding paper of Jean et al. (CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations.

Post-Quantum Authenticated Encryption against Chosen-Ciphertext Side-Channel Attacks

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2022
Over the last years, the side-channel analysis of Post-Quantum Cryptography (PQC) candidates in the NIST standardization initiative has received increased attention.

The Definition and Software Performance of Hashstream, a Fast Length-Flexible PRF

open access: yesCryptography, 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

open access: yesCryptography, 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

open access: yesIACR 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-
