Voltage Fault Injection Attack on Key Expansion of AES [PDF]

Jisuanji gongcheng, 2019
Aiming at the Advanced Encryption Standard(AES) algorithm,this paper proposes a simple and efficient method of fault injection attack.By instantaneously reducing the voltage of the cipher chip power supply,the low voltage burr is generated,which causes ...

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.

Experimental evaluation of differential fault attack on lightweight block cipher PIPO

IET Information Security, 2023
The recent development of Internet of Things (IoT) devices has increased related security issues. Because of the rapid increase in the use of these devices, the possibility of accessing and hijacking cryptographic devices is increasing.

A fault attack on the Niederreiter cryptosystem using binary irreducible Goppa codes [PDF]

Groups, Complexity, Cryptology, 2020
A fault injection framework for the decryption algorithm of the Niederreiter public-key cryptosystem using binary irreducible Goppa codes and classical decoding techniques is described. In particular, we obtain low-degree polynomial equations in parts of

Persistent Fault Analysis on Block Ciphers

Transactions on Cryptographic Hardware and Embedded Systems, 2018
Persistence is an intrinsic nature for many errors yet has not been caught enough attractions for years. In this paper, the feature of persistence is applied to fault attacks, and the persistent fault attack is proposed.

An Effective Simulation Analysis of Transient Electromagnetic Multiple Faults

Sensors, 2020
Embedded encryption devices and smart sensors are vulnerable to physical attacks. Due to the continuous shrinking of chip size, laser injection, particle radiation and electromagnetic transient injection are possible methods that introduce transient ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

When the Decoder Has to Look Twice: Glitching a PUF Error Correction

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Physical Unclonable Functions (PUFs) have been increasingly used as an alternative to non-volatile memory for the storage of cryptographic secrets. Research on side channel and fault attacks with the goal of extracting these secrets has begun to gain ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.
