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 s...
Duel of the Titans: The Romulus and Remus Families of Lightweight AEAD Algorithms
Authenticated encryption lightweight cryptography tweakable block cipher
2019/9/3
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 ...
SAEB: A Lightweight Blockcipher-Based AEAD Mode of Operation
Lightweight cryptography authenticated encryption with associated data blockciphe
2019/6/14
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 n...
We 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 ga...
TEDT, a Leakage-Resilient AEAD mode for High (Physical) Security Applications
Authenticated encryption re-keying tweakable block cipher
2019/2/26
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 asymptotically optimal s...
