DNS Cache Poisoning Attack: Resurrections with Side Channels
By Technical Paper Link - 19 Nov, 2021 - Comments: 0

Abstract "DNS is one of the fundamental and ancient protocols on the Internet that supports many network applications and services. Unfortunately, DNS was designed without security in mind and is subject to a variety of serious attacks, one of which is the well-known DNS cache poisoning attack. Over the decades of evolution, it has proven extraordinarily challenging to retrofit strong security... » read more

Bandwidth Utilization Side-Channel On ML Inference Accelerators
By Arm - 10 Nov, 2021 - Comments: 0

Abstract—Accelerators used for machine learning (ML) inference provide great performance benefits over CPUs. Securing confidential model in inference against off-chip side-channel attacks is critical in harnessing the performance advantage in practice. Data and memory address encryption has been recently proposed to defend against off-chip attacks. In this paper, we demonstrate that bandwidth... » read more

Topics include side-channel attacks and defenses, embedded security, hardware security tokens, and more. Here are some highlights with associated links:   [tab... » 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

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

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

Scaling Anti-Tamper Protection To Meet Escalating Threats
By Scott Best - 04 Jun, 2020 - Comments: 0

Anti-tamper tends to be one of those catchall phrases encompassing any countermeasure on a security chip. A more precise definition would be that anti-tamper protection is any collection of countermeasures that serves to thwart an adversary’s attempt to monitor or affect the correct operation of a chip or a security core within a chip. Given that, it can be useful to think about a hierarchy o... » read more

Power/Performance Bits: March 24
By Jesse Allen - 24 Mar, 2020 - Comments: 0

Backscatter Wi-Fi radio Engineers at the University of California San Diego developed an ultra-low power Wi-Fi radio they say could enable portable IoT devices. Using 5,000 times less power than standard Wi-Fi radios, the device consumes 28 microwatts while transmitting data at a rate of 2 megabits per second over a range of up to 21 meters. "You can connect your phone, your smart devices, ... » read more
