Duel of the Titans: The Romulus and Remus Families of Lightweight AEAD Algorithms [PDF]
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.

Exploring Integrity of AEADs with Faults: Definitions and Constructions
IACR Transactions on Symmetric Cryptology, 2022 Implementation-based attacks are major concerns for modern cryptography. For symmetric-key cryptography, a significant amount of exploration has taken place in this regard for primitives such as block ciphers.

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 ...

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.

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.

TEDT, a Leakage-Resist AEAD Mode for High Physical Security Applications
Transactions on Cryptographic Hardware and Embedded Systems, 2019 We propose TEDT, a new Authenticated Encryption with Associated Data (AEAD) mode leveraging Tweakable Block Ciphers (TBCs). TEDT provides the following features: (i) It offers full leakage-resistance, that is, it limits the exploitability of physical ...
