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

IET Computers &Digital Techniques, Volume 17, Issue 3-4, Page 75-88, May-July 2023., 2023 A comprehensive evaluation of the seven (out of 10) algorithm finalists of the NIST IoT lightweight cipher competition that do not integrate built‐in countermeasures is proposed. The study shows that, nonetheless, they still present some residual vulnerabilities to power SCA.

Overhang Saddle Fin Sidewall Structure for Highly Reliable DRAM Operation
IEEE Access, 2023 A novel memory cell transistor structure based on a saddle fin-based DRAM is presented for highly reliable operations. The overhang saddle fin (oss-fin) active structure is formed by two steps of etching of the fin; isotropic etching for the short side ...

Characterization of Program Behavior under Faulty Instruction Encoding
Scientific Programming, Volume 2022, Issue 1, 2022., 2022 As process technology scales, electronic devices become more susceptible to soft errors. Soft errors can lead to silent data corruptions (SDCs), seriously compromising the reliability of a system. Researchers have explored error resilient encodings, which leverage crash patterns to detect SDCs.

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

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 ...

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 ...
