Correction Fault Attack on CROSS under Unknown Bit Flips

Transactions on Cryptographic Hardware and Embedded Systems
Recognising the need for PQC signature schemes with different sizes and performance trade-offs than the ML-DSA and SLH-DSA standards, in 2023, NIST launched a competition for additional signature algorithms.

ALARM: Active LeArning of Rowhammer Mitigations

, 2022
Rowhammer is a serious security problem of contemporary dynamic random-access memory (DRAM) where reads or writes of bits can flip other bits. DRAM manufacturers add mitigations, but don't disclose details, making it difficult for customers to evaluate ...

An Analysis of HMB-based SSD Rowhammer [PDF]

Rowhammer has been shown to be an extensive attack vector. In the years since its discovery, numerous exploits have been shown, attacking a wide range of targets from kernels, through web browsers to machine learning models. These attacks were not always

SMASH: Synchronized many-sided rowhammer attacks from JavaScript

, 2021
Despite their in-DRAM Target Row Refresh (TRR) mitigations, some of the most recent DDR4 modules are still vulnerable to many-sided Rowhammer bit flips.

Drammer: Deterministic Rowhammer attacks on mobile platforms

, 2016
Recent work shows that the Rowhammer hardware bug can be used to craft powerful attacks and completely subvert a system. However, existing efforts either describe probabilistic (and thus unreliable) attacks or rely on special (and often unavailable ...

BlockHammer: Preventing RowHammer at Low Cost by Blacklisting Rapidly-Accessed DRAM Rows

, 2021
Aggressive memory density scaling causes modern DRAM devices to suffer from RowHammer, a phenomenon where rapidly activating a DRAM row can cause bit-flips in physically-nearby rows.
