Analysis of an Optimal Fault Attack on the LED-64 Lightweight Cryptosystem

IEEE Access, 2019
This paper presents an optimal method for recovering the secret keys of the light encryption device (LED) by combining the impossible differential fault attack with the algebraic differential fault attack. The proposed optimal method effectively improves

Differential fault attack on Zorro block cipher [PDF]

Security and Communication Networks, 2015
AbstractZorro is a 24‐round block cipher presented at the CHES 2013 conference. In this paper, we propose a differential fault attack on Zorro under a byte fault model, in which faults are injected in the 20th round of Zorro at arbitrary positions. With two fault injections on average, a candidate set for the key of the cipher with at most 224 elements

A Fault Attack on the Family of Enocoro Stream Ciphers

Cryptography, 2021
A differential fault attack framework for the Enocoro family of stream ciphers is presented. We only require that the attacker can reset the internal state and inject a random byte-fault, in a random register, during a known time period.

A Novel DFA on AES: Based on Two–Byte Fault Model with Discontiguous Rows

Applied Sciences, 2023
Differential fault attack (DFA) is a distinctive methodology for acquiring the key to block ciphers, which comprises two distinct strategies: DFA on the state and DFA on the key schedule. Given the widespread adoption of the Advanced Encryption Standard (

Differential Fault Attacks on Deterministic Lattice Signatures

IACR Transactions on Cryptographic Hardware and Embedded Systems, 2018
In this paper, we extend the applicability of differential fault attacks to lattice-based cryptography. We show how two deterministic lattice-based signature schemes, Dilithium and qTESLA, are vulnerable to such attacks. In particular, we demonstrate that single random faults can result in a nonce-reuse scenario which allows key recovery.
