Securing 5G And IoT With Fuzzing
By Synopsys - 04 Aug, 2021 - Comments: 0

5G will revolutionize many industries, with up to 100 times the speed, 100 times the capacity, and one-tenth the latency compared to 4G LTE. But in addition to providing superior performance, 5G expands the attack surface of apps and IoT devices that rely on this next-gen network. In addition to known security exploits, we’re bound to see unknown, novelty attacks. Fuzz testing (or fuzzing)... » read more

Graphene-based PUFs that are reconfigurable and resilient to ML attacks
By Technical Paper Link - 27 Jul, 2021 - Comments: 0

Researchers at Pennsylvania State University propose using graphene to create physically unclonable functions (PUFs) that are energy efficient, scalable, and secure against AI attacks. Abstract "Graphene has a range of properties that makes it suitable for building devices for the Internet of Things. However, the deployment of such devices will also likely require the development of s... » read more

TimeCache: Using Time to Eliminate Cache Side Channels when Sharing Software
By Technical Paper Link - 14 Jun, 2021 - Comments: 0

"Abstract—Timing side channels have been used to extract cryptographic keys and sensitive documents even from trusted enclaves. Specifically, cache side channels created by reuse of shared code or data in the memory hierarchy have been exploited by several known attacks, e.g., evict+reload for recovering an RSA key and Spectre variants for leaking speculatively loaded data. In this paper, we ... » read more

Is There a Practical Test For Rowhammer Vulnerability?
By Bryon Moyer - 08 Jun, 2021 - Comments: 3

Rowhammer is proving to be a difficult DRAM issue to fix. While efforts continue to mitigate or eliminate the effect, no solid solution has yet made it to volume production. In addition, more aggressive process nodes are expected to exacerbate the problem. In the absence of a fix, then, testing may be one way to give DRAM manufacturers and users some way to segregate devices that are more su... » read more

IC Security Threat Grows As More Devices Are Connected
By Ann Mutschler - 06 May, 2021 - Comments: 0

Designing for security is beginning to gain traction across a wider swath of chips and systems as more of them are connected to the Internet and to each other, sometimes in safety- and mission-critical markets where the impact of a cyber attack can be devastating. But it's also becoming more difficult to design security into these systems. Unlike in the past, connectivity is now considered e... » read more

A Novel PUF Using Stochastic Short-Term Memory Time of Oxide-Based RRAM for Embedded Applications
By Technical Paper Link - 31 Mar, 2021 - Comments: 0

Abstract: "RRAM suffers from poor retention with short-term memory time when using low compliance current for programing. However, the short-term memory time exhibits ideal randomness, which can be exploited as an entropy source for physically unclonable function (PUF). In this work, we demonstrated a novel PUF utilizing the stochastic short-term memory time of oxide-based RRAM. The proposed P... » read more

COVID-19 And Cybersecurity: Pay Attention To Exponential Growth!
By Andreas Kuehlmann - 08 Mar, 2021 - Comments: 0

COVID-19 and cybersecurity – you may wonder what these two seemingly very different topics have in common. I would list two: Both of them are exponential in nature, which, as a society we have difficulties grappling with – making this one of the reasons for our uneven responses. Both of them require a multi-layered solution strategy that, while it does not need to be perfect, must b... » read more

Security Provisioning Moves Out Of The Factory
By Bryon Moyer - 04 Mar, 2021 - Comments: 1

Security credentials traditionally have been provisioned during chip manufacturing, often as a final part of the testing process. That's starting to change. Logistics management can be improved by pushing that process out — even as far as the on-boarding process. And simpler on-boarding can hide most of the details from the user. “The IT approach to provisioning IoT devices has primar... » read more

A Machine-Learning-Resistant 3D PUF with 8-layer Stacking Vertical RRAM and 0.014% Bit Error Rate Using In-Cell Stabilization Scheme for IoT Security Applications
By Technical Paper Link - 03 Mar, 2021 - Comments: 0

Abstract: "In this work, we propose and demonstrate a multi-layer 3-dimensional (3D) vertical RRAM (VRRAM) PUF with in-cell stabilization scheme to improve both cost efficiency and reliability. An 8-layer VRRAM array was manufactured with excellent uniformity and good endurance of >10 7 . Apart from the variation in RRAM resistance, enhanced randomness is obtained thanks to the parasitic IR... » read more
