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 ...

Nonces Are Noticed: AEAD Revisited
2019We draw attention to a gap between theory and usage of nonce-based symmetric encryption, under which the way the former treats nonces can result in violation of privacy in the latter. We bridge the gap with a new treatment of nonce-based symmetric encryption that modifies the syntax (decryption no longer takes a nonce), upgrades the security goal ...

Remus: Lighweight AEAD from Ideal Ciphers
2021Remus can be seen as a more aggressive brother of Romulus. It is a family of authenticated encryption with associated data (AEAD) schemes based on a tweakable block cipher (TBC) Skinny. Remus consists of two families, a nonce-based AE (NAE) Remus-N and a nonce misuse-resistant AE (MRAE) Remus-M.

A Lightweight AEAD encryption core to secure IoT applications
2020 IEEE Asia Pacific Conference on Circuits and Systems (APCCAS), 2020The Internet of Things (IoT) with the advancements of many technologies opens a wide range of new applications such as smart appliances, smart cities and smart grids. Despite its popularity and usability, it also creates a new attack surface for the hackers especially on highly constrained devices which have limited memory footprints and processing ...

NORX: Parallel and Scalable AEAD
2014This paper introduces NORX, a novel authenticated encryption scheme supporting arbitrary parallelism degree and based on ARX primitives, yet not using modular additions. NORX has a unique parallel architecture based on the monkeyDuplex construction, with an original domain separation scheme for a simple processing of header, payload and trailer data ...

Romulus: Lighweight AEAD from Tweakable Block Ciphers
2021In this chapter, we present the NIST lightweight finalist, Romulus. It is a family of lightweight, very efficient, and highly-secure algorithms; including, but not restricted to, NAE (Romulus-N) and MRAE (Romulus-M) schemes.

Near birthday attack on “$8$ bits” $\mathsf{AEAD}$ mode
Математические вопросы криптографии, 2019Представлена атака на режим аутентифицированного шифрования ($\mathsf{AEAD}$-режим) «$8$ бит», который являлся одним из кандидатов на роль стандартизованного российского $\mathsf{AEAD}$-режима. Режим «8 бит» отличается от режима $\mathrm{CCM}$ несколькими конструктивными особенностями.

Improved differential fault analysis of Grain128-AEAD
Journal of Surveillance, Security and SafetyThe number of smart devices connected to the Internet has been constantly increasing, and as a result, lightweight cryptography (LWC) has become more important in the past decade. The Lightweight Cryptography (LWC) Project is an initiative taken by the National Institute of Standards and Technology (NIST) to standardize such LWC algorithms.
