The Early Bird Gets More Secure Hardware
By Rob van Blommestein - 02 Sep, 2021 - Comments: 0

I’m sure you’ve heard the expression “The early bird gets the worm.” This proverb emphasizes the importance of starting something early to maximize the potential outcome. In terms of hardware security, this idiom is spot on. Cybersecurity shouldn’t only be about protecting the software from attacks. Hardware is just as important. Cyberattacks continue to advance significantly, prog... » read more

Always On, Always At Risk
By Ed Sperling - 18 Aug, 2021 - Comments: 0

Always-on devices are everywhere, and each of them is a potential target for hackers. While many people associate always-on devices with smart speakers such as an Amazon Alexa or Google Home, or a connected security camera, that's only one component in a system. There's a broader infrastructure behind those devices. So even if you power down a digital assistant/smart speaker, everything it's... » read more

Leaky Buddies: Cross-Component Covert Channels on Integrated CPU-GPU Systems
By Technical Paper Link - 11 Aug, 2021 - Comments: 0

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

IChannels: Exploiting Current Management Mechanisms to Create Covert Channels in Modern Processors
By Technical Paper Link - 11 Aug, 2021 - Comments: 0

Find technical paper link here. Abstract: "To operate efficiently across a wide range of workloads with varying power requirements, a modern processor applies different current management mechanisms, which briefly throttle instruction execution while they adjust voltage and frequency to accommodate for power-hungry instructions (PHIs) in the instruction stream. Doing so 1) reduces the pow... » read more

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
