IACR Transactions on Symmetric Cryptology, 2020 We present the family of authenticated encryption schemes SKINNY-AEAD and the family of hashing schemes SKINNY-Hash. All of the schemes employ a member of the SKINNY family of tweakable block ciphers, which was presented at CRYPTO 2016, as the underlying

On the Plaintext Awareness of AEAD Schemes
IACR Transactions on Symmetric CryptologyPlaintext-awareness of AEAD schemes is one of the more obscure and easily misunderstood notions. Originally proposed by Andreeva et al., Mennink and Talnikar showed in 2025 that the original definitions are vague and leave too much room for ...

SAEB: A Lightweight Blockcipher-Based AEAD Mode of Operation
Transactions on Cryptographic Hardware and Embedded Systems, 2018 Lightweight cryptography in computationally constrained devices is actively studied. In contrast to advances of lightweight blockcipher in the last decade, lightweight mode of operation is seemingly not so mature, yet it has large impact in performance ...

Lightweight AEAD and Hashing using the Sparkle Permutation Family [PDF]
IACR Transactions on Symmetric Cryptology, 2020 We introduce the Sparkle family of permutations operating on 256, 384 and 512 bits. These are combined with the Beetle mode to construct a family of authenticated ciphers, Schwaemm, with security levels ranging from 120 to 250 bits.

Context-Committing Security of Leveled Leakage-Resilient AEAD
IACR Transactions on Symmetric CryptologyDuring recent years, research on authenticated encryption has been thriving through two highly active and practically motivated research directions: provable leakage resilience and key- or context-commitment security.

Duel of the Titans: The Romulus and Remus Families of Lightweight AEAD Algorithms
IACR Transactions on Symmetric Cryptology, 2020 In this article, we propose two new families of very lightweight and efficient authenticated encryption with associated data (AEAD) modes, Romulus and Remus, that provide security beyond the birthday bound with respect to the block-length n.

The dynamics of vegetation diversity and biomass under traditional grazing in Ethiopia's Somali rangeland. [PDF]
Plant Environ Interact, 2023 This study explores the impact of different grazing management practices on vegetation attributes in the Somali pastoral ecosystem of Ethiopia. It examines herbaceous species diversity, composition, growth forms (grass vs. forbs), life forms (annuals vs.

Energy Analysis of Lightweight AEAD Circuits [PDF]
, 2020 The selection criteria for NIST’s Lightweight Crypto Standardization (LWC) have been slowly shifting towards the lightweight efficiency of designs, given that a large number of candidates already establish their security claims on conservative, well-studied paradigms.

Power Yoga: Variable-Stretch Security of CCM for Energy-Efficient Lightweight IoT
IACR Transactions on Symmetric Cryptology, 2021 The currently ongoing NIST LWC project aims at identifying new standardization targets for lightweight authenticated encryption with associated data (AEAD) and (optionally) lightweight cryptographic hashing.

Subverting Decryption in AEAD [PDF]
, 2019 This work introduces a new class of Algorithm Substitution Attack (ASA) on Symmetric Encryption Schemes. ASAs were introduced by Bellare, Paterson and Rogaway in light of revelations concerning mass surveillance. An ASA replaces an encryption scheme with a subverted version that aims to reveal information to an adversary engaged in mass surveillance ...
