Software-only Rowhammer Attacks and Countermeasures [PDF]
, 2021 Rowhammer is a hardware vulnerability in DRAM memory, where repeated access to memory (i.e., hammer rows) can induce bit flips in neighboring memory locations (i.e., victim rows).

Uncovering In-DRAM RowHammer Protection Mechanisms: A New Methodology, Custom RowHammer Patterns, and Implications [PDF]
, 2022 The RowHammer vulnerability in DRAM is a critical threat to system security. To protect against RowHammer, vendors commit to security-through-obscurity: modern DRAM chips rely on undocumented, proprietary, on-die mitigations, commonly known as Target Row

Investigating the Practical Limits of Rowhammer Attacks
, 2023 The objective of this thesis is to conduct an in-depth analysis of the Rowhammer phenomenon. Rowhammer is a specific issue that results in the selective corruption of data within DRAM memories, triggered by specific memory access patterns.

Fundamentally Understanding and Solving RowHammer
, 2023 We provide an overview of recent developments and future directions in the RowHammer vulnerability that plagues modern DRAM (Dynamic Random Memory Access) chips, which are used in almost all computing systems as main memory. RowHammer is the phenomenon

Persistent Fault Attack in Practice
Transactions on Cryptographic Hardware and Embedded Systems, 2020 Persistence fault analysis (PFA) is a novel fault analysis technique proposed in CHES 2018 and demonstrated with rowhammer-based fault injections. However, whether such analysis can be applied to traditional fault attack scenario, together with its ...

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.
