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.

CacheZoom: How SGX Amplifies The Power of Cache Attacks [PDF]

, 2017
In modern computing environments, hardware resources are commonly shared, and parallel computation is widely used. Parallel tasks can cause privacy and security problems if proper isolation is not enforced.

ALARM: Active LeArning of Rowhammer Mitigations

Proceedings of the 11th International Workshop on Hardware and Architectural Support for Security and Privacy, 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 their efficacy.

Exploiting Inter- and Intra-Memory Asymmetries for Data Mapping in Hybrid Tiered-Memories

, 2020
Modern computing systems are embracing hybrid memory comprising of DRAM and non-volatile memory (NVM) to combine the best properties of both memory technologies, achieving low latency, high reliability, and high density.

Defeating Software Mitigations Against Rowhammer: A Surgical Precision Hammer [PDF]

, 2018
With software becoming harder to compromise due to modern defenses, attackers are increasingly looking at exploiting hardware vulnerabilities such as Rowhammer. In response, the research community has developed several software defenses to protect existing hardware against this threat.

Improving Phase Change Memory Performance with Data Content Aware Access

, 2020
A prominent characteristic of write operation in Phase-Change Memory (PCM) is that its latency and energy are sensitive to the data to be written as well as the content that is overwritten.

SpyHammer: Understanding and Exploiting RowHammer Under Fine-Grained Temperature Variations

IEEE Access
RowHammer is a DRAM vulnerability that can cause bit errors in a victim DRAM row solely by accessing its neighboring DRAM rows at a high-enough rate. Recent studies demonstrate that new DRAM devices are becoming increasingly vulnerable to RowHammer, and ...

Fault Sneaking Attack: a Stealthy Framework for Misleading Deep Neural Networks

, 2019
Despite the great achievements of deep neural networks (DNNs), the vulnerability of state-of-the-art DNNs raises security concerns of DNNs in many application domains requiring high reliability.We propose the fault sneaking attack on DNNs, where the ...

Nethammer: Inducing Rowhammer Faults through Network Requests [PDF]

2020 IEEE European Symposium on Security and Privacy Workshops (EuroS&PW), 2020
A fundamental assumption in software security is that memory contents do not change unless there is a legitimate deliberate modification. Classical fault attacks show that this assumption does not hold if the attacker has physical access. Rowhammer attacks showed that local code execution is already sufficient to break this assumption.
