AKER: A Design and Verification Framework for Safe and Secure SoC Access Control
By Technical Paper Link - 12 Nov, 2021 - Comments: 0

Abstract: "Modern systems on a chip (SoCs) utilize heterogeneous architectures where multiple IP cores have concurrent access to on-chip shared resources. In security-critical applications, IP cores have different privilege levels for accessing shared resources, which must be regulated by an access control system. AKER is a design and verification framework for SoC access control. AKER builds ... » read more

Netlist Decompilation Workflow for Recovered Design Verification, Validation, and Assurance
By Technical Paper Link - 12 Nov, 2021 - Comments: 0

Abstract: "Over the last few decades, the cost and difficulty of producing integrated circuits at ever shrinking node sizes has vastly increased, resulting in the manufacturing sector moving overseas. Using offshore foundries for chip fabrication, however, introduces new vulnerabilities into the design flow since there is little to no observability into the manufacturing process. At the same ... » read more

HECTOR-V: A Heterogeneous CPU Architecture for a Secure RISC-V Execution Environment
By Technical Paper Link - 09 Nov, 2021 - Comments: 0

Summary "To ensure secure and trustworthy execution of applications, vendors frequently embed trusted execution environments into their systems. Here, applications are protected from adversaries, including a malicious operating system. TEEs are usually built by integrating protection mechanisms directly into the processor or by using dedicated external secure elements. However, both of these... » read more

By Technical Paper Link - 28 Oct, 2021 - Comments: 0

"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
By Technical Paper Link - 11 Oct, 2021 - Comments: 0

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
By Technical Paper Link - 11 Oct, 2021 - Comments: 0

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
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

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
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

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
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

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
By Technical Paper Link - 08 Sep, 2021 - Comments: 0

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
