2021 CWE Most Important Hardware Weaknesses


"The 2021 CWE™ Most Important Hardware Weaknesses is the first of its kind and the result of collaboration within the Hardware CWE Special Interest Group (SIG), a community forum for individuals representing organizations within hardware design, manufacturing, research, and security domains, as well as academia and government. The goals for the 2021 Hardware List are to drive awarenes... » read more

Multicolored Nanocolloidal Hydrogel Inks For Anti-Counterfeiting


Abstract "Nanocolloidal gels are emerging as a promising class of materials with applications as inks in 2D and 3D printing. Polymer nanoparticles (NPs) offer many advantages as potential building blocks of nanocolloidal gels, due to the ability to control NP dimensions, charge, surface chemistry, and functionality; however, their applications as inks in printing are yet to be explored. Here, ... » read more

Probe assisted localized doping of aluminum into silicon substrates


Abstract "This paper discusses the development of a rapid, large-scale integration of deterministic dopant placement technique for encoding information in physical structures at the nanoscale. The doped structures inherit identical and customizable radiofrequency (RF) electronic signature, which could be leveraged into an identification feature unique to the tag item. This will allow any manuf... » read more

PTAuth: Temporal Memory Safety via Robust Points-to Authentication


Authors: Reza Mirzazade Farkhani, Mansour Ahmadi, and Long Lu, Northeastern University Abstract: "Temporal memory corruptions are commonly exploited software vulnerabilities that can lead to powerful attacks. Despite significant progress made by decades of research on mitigation techniques, existing countermeasures fall short due to either limited coverage or overly high overhead. Further... » read more

Database Reconstruction from Noisy Volumes: A Cache Side-Channel Attack on SQLite


Authors: Aria Shahverdi, University of Maryland; Mahammad Shirinov, Bilkent University; Dana Dachman-Soled, University of Maryland Abstract: "We demonstrate the feasibility of database reconstruction under a cache side-channel attack on SQLite. Specifically, we present a Flush+Reload attack on SQLite that obtains approximate (or "noisy") volumes of range queries made to a private database... » read more

SMASH: Synchronized Many-sided Rowhammer Attacks from JavaScript


Authors: Finn de Ridder, ETH Zurich and VU Amsterdam; Pietro Frigo, Emanuele Vannacci, Herbert Bos, and Cristiano Giuffrida, VU Amsterdam; Kaveh Razavi, ETH Zurich Abstract: "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. While these bit flips are exploitable from native code, tri... » read more

Automatic Extraction of Secrets from the Transistor Jungle using Laser-Assisted Side-Channel Attacks


Abstract:  "The security of modern electronic devices relies on secret keys stored on secure hardware modules as the root-of-trust (RoT). Extracting those keys would break the security of the entire system. As shown before, sophisticated side-channel analysis (SCA) attacks, using chip failure analysis (FA) techniques, can extract data from on-chip memory cells. However, since the chip's... » read more

On the Design and Misuse of Microcoded (Embedded) Processors — A Cautionary Note


Abstract:  "Today's microprocessors often rely on microcode updates to address issues such as security or functional patches. Unfortunately, microcode update flexibility opens up new attack vectors through malicious microcode alterations. Such attacks share many features with hardware Trojans and have similar devastating consequences for system security. However, due to microcode's opaq... » read more

Usability of Authenticity Checks for Hardware Security Tokens


Abstract:  "The final responsibility to verify whether a newly purchased hardware security token (HST) is authentic and unmodified lies with the end user. However, recently reported attacks on such tokens suggest that users cannot take the security guarantees of their HSTs for granted, even despite widely deployed authenticity checks. We present the first comprehensive market review eva... » read more

Leaky Buddies: Cross-Component Covert Channels on Integrated CPU-GPU Systems


Find Technical Paper link here. Abstract: "Graphics Processing Units (GPUs) are ubiquitous components used across the range of today’s computing platforms, from phones and tablets, through personal computers, to high-end server class platforms. With the increasing importance of graphics and video workloads, recent processors are shipped with GPU devices that are integrated on the same chi... » read more
