Comprehensive Performance Study of Zero-Knowledge Proofs on GPUs (Univ. of Michigan)


A new technical paper titled "ZKProphet: Understanding Performance of Zero-Knowledge Proofs on GPUs" was published by researchers at University of Michigan. Abstract "Zero-Knowledge Proofs (ZKP) are protocols which construct cryptographic proofs to demonstrate knowledge of a secret input in a computation without revealing any information about the secret. ZKPs enable novel applications in p... » read more

Rethinking Security In Semiconductor Testing: Why Containment Is The New Imperative


It’s nearly impossible to keep up with the headlines without stumbling upon another major cybersecurity incident. According to recent reports, 2024 witnessed a staggering 5.5 billion breaches globally. In the United States alone, the average cost of a single data breach clocked in at $9.36 million—slightly lower than 2023’s figure, but still a significant hit for any organization. On a gl... » read more

How The Cyber Resilience Act Shifts Open-Source Responsibility To Vendors


The EU Cyber Resilience Act (CRA), adopted last year, aims to strengthen product security in several ways. One of its most ambitious goals is the elimination of exploitable vulnerabilities from digital products. Vendors are now obligated to identify vulnerabilities, resolve them before delivery, and continue addressing them throughout the product’s lifecycle. The scale of the challenge The ... » read more

Countering Security Threats Of Quantum Attacks With PSOC Control Microcontrollers


Quantum computers of appropriate power are expected to break traditional public-key encryption such as ECC and RSA. Quantum computers that will be able to mount attacks on public-key cryptography are commonly referred to as 'Cryptographically Relevant Quantum Computers’ (CRQCs). Betting on the future existence of CRQCs, attackers may also harvest encrypted data today and to decrypt it later o... » read more

New Approaches To Limit Cyberattacks On Hardware


The number and value of cyberattacks on semiconductors is rising, but new approaches to designing and packaging chips could put a significant dent in those figures. Semiconductor-related cybersecurity attacks have multiplied more than six times since 2022, according to a report by cyber intelligence firm CloudSEK. These attacks have cost the semiconductor industry an estimated $1.05 billion ... » read more

New Spectre Branch Target Injection, Spectre-BTI, Attack Primitives On CPUs (ETH Zurich)


A new technical paper titled “VMSCAPE: Exposing and Exploiting Incomplete Branch Predictor Isolation in Cloud Environments” was published by researchers at ETH Zurich. Abstract “Virtualization is a cornerstone of modern cloud infrastructures, providing the required isolation to customers. This isolation, however, is threatened by speculative execution attacks which the CPU vendors att... » read more

Security Technical Paper Roundup: Sept. 30


A number of hardware security-related technical papers were presented at the August 2025 USENIX Security Symposium. The organization provides open access research, and the presentation slides and papers are free to the public. Topics include side-channel attacks and defenses, embedded security, fuzzing, fault injection, rowhammer, and more. Here are some highlights with associated links: [ta... » read more

Undervolting Attack That Exploits The Vulnerability Of Chips During Brownout Conditions (Worcester Polytechnic, RUB)


A new technical paper titled "Chypnosis: Stealthy Secret Extraction using Undervolting-based Static Side-channel Attacks" was published by researcher at Worcester Polytechnic Institute and Ruhr University Bochum. Abstract: "Static side-channel analysis attacks, which rely on a stopped clock to extract sensitive information, pose a growing threat to embedded systems' security. To protect a... » read more

HW Security: 2.5D and 3D Technologies Provide Opportunities in Designing Secure Systems (UCSB, Columbia)


A new technical paper titled "Leveraging 3D Technologies for Hardware Security: Opportunities and Challenges" was published by researchers at the University of California, Santa Barbara and Columbia University. Abstract "3D die stacking and 2.5D interposer design are promising technologies to improve integration density, performance and cost. Current approaches face serious issues in dealin... » read more

How Security Regulation Can Help Grid Stability


Grid stability is at risk. The advent of Distributed Energy Resources (DERs), such as solar, wind, and batteries, has increased the attack surface of energy generation. While cities once had few power plants, they now host thousands of smaller, intermittent sources. These DERs are often managed by entities without uptime requirements. At the same time, traditional energy sources face greater de... » read more
