How Practical Are Fault Injection Attacks, Really?
IEEE Access, 2022 Fault injection attacks (FIA) are a class of active physical attacks, mostly used for malicious purposes such as extraction of cryptographic keys, privilege escalation, attacks on neural network implementations. There are many techniques that can be used

Fundamentally Understanding and Solving RowHammer
Proceedings of the 28th Asia and South Pacific Design Automation Conference, 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 in which repeatedly accessing a row in a real DRAM chip causes bitflips (i.e., data corruption) in ...

JackHammer: Efficient Rowhammer on Heterogeneous FPGA-CPU Platforms
Transactions on Cryptographic Hardware and Embedded Systems, 2020 After years of development, FPGAs are finally making an appearance on multi-tenant cloud servers. Heterogeneous FPGA-CPU microarchitectures require reassessment of common assumptions about isolation and security boundaries, as they introduce new attack ...

Proceedings of the 2016 ACM SIGSAC Conference on Computer and Communications Security, 2016 Recent work shows that the Rowhammer hardware bug can be used to craft powerful attacks and completely subvert a system. However, existing e orts either describe probabilistic (and thus unreliable) attacks or rely on special (and often unavailable) memory management features to place victim objects in vulnerable physical memory locations.

CAT-TWO: Counter-Based Adaptive Tree, Time Window Optimized for DRAM Row-Hammer Prevention
IEEE Access, 2020 Row-hammering flips bits in a victim DRAM row by frequently activating its adjacent rows, compromising DRAM integrity. Several studies propose to prevent row-hammering by counting the number of activates to a DRAM row and refreshing the corresponding ...

LightRoAD: Lightweight Rowhammer Attack Detector
2021 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2021 Dynamic Random Access Memory (DRAM)-based systems are widely used in mobile and portable applications where low-cost and high-storage memory capability are required. However, such systems are prone to attacks. A latent threat to DRAM-based system security is the so-called Rowhammer attacks. By repeatedly accessing memory, an attacker is able to perform

SCM : Secure Code Memory Architecture [PDF]
, 2017 An increasing number of applications implemented on a SoC (System-on-chip) require security features. This work addresses the issue of protecting the integrity of code and read-only data that is stored in memory.

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 ...

The AGI Containment Problem [PDF]
, 2016 There is considerable uncertainty about what properties, capabilities and motivations future AGIs will have. In some plausible scenarios, AGIs may pose security risks arising from accidents and defects. In order to mitigate these risks, prudent early AGI
