Algebraic Side Channel Attack on Trivium and Grain Ciphers

open access: yesIEEE Access, 2017
Solving a system of multivariate quadratic equations obtained through algebraic cryptanalysis is a nondeterministic polynomial time-complete problem. Owing to the trend of stream ciphers based on nonlinear update, the success of algebraic attacks has ...

Sabotage Attack Detection for Additive Manufacturing Systems

open access: yesIEEE Access, 2020
This paper presents a novel multi-modal sabotage attack detection system for Additive Manufacturing (AM) machines. By utilizing multiple side-channels, we improve system state estimation significantly in comparison to uni-modal techniques.

Multiple-Valued Plaintext-Checking Side-Channel Attacks on Post-Quantum KEMs

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2023
In this paper, we present a side-channel analysis (SCA) on key encapsulation mechanisms (KEMs) based on the Fujisaki–Okamoto (FO) transformation and its variants.

Algebraic Side-Channel Attacks [PDF]

open access: yes, 2010
In 2002, algebraic attacks using overdefined systems of equations have been proposed as a potentially very powerful cryptanalysis technique against block ciphers. However, although a number of convincing experiments have been performed against certain reduced algorithms, it is not clear whether these attacks can be successfully applied in general and ...

Trojan-horse attacks threaten the security of practical quantum cryptography [PDF]

open access: yes, 2014
A quantum key distribution system may be probed by an eavesdropper Eve by sending in bright light from the quantum channel and analyzing the back-reflections. We propose and experimentally demonstrate a setup for mounting such a Trojan-horse attack.

Dynamic migration method of key virtual network function based on risk awareness

open access: yesTongxin xuebao, 2020
Aiming at the problems that traditional dynamic migration methods have many migration nodes,high migration frequency,and long service function chain (SFC) link path after migration when dealing with side channel attack,a dynamic migration method of ...

Colored Petri Net Based Cache Side Channel Vulnerability Evaluation

open access: yesIEEE Access, 2019
The cache side channel leakage is a very serious security issue in the information security field. In order to solve this problem, a large number of security mechanisms have been applied to protect the cache.

DR.SGX: Hardening SGX Enclaves against Cache Attacks with Data Location Randomization

open access: yes, 2019
Recent research has demonstrated that Intel's SGX is vulnerable to software-based side-channel attacks. In a common attack, the adversary monitors CPU caches to infer secret-dependent data accesses patterns. Known defenses have major limitations, as they

Defeating Hardware Prefetchers in Flush+Reload Side-Channel Attack

open access: yesIEEE Access, 2021
Hardware prefetching can seriously interfere with Flush+Reload cache side channel attack. This interference is not taken into consideration in previous Flush+Reload attacks.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
