Radiation-induced transient faults affecting integrated circuits pose significant reliability challenges for safety-critical information systems. While hardware-based mitigation is traditional, it often precludes the use of cost-effective Commercial-Off-The-Shelf (COTS) components due to competing non-functional requirements. Software-Implemented Hardware Fault Tolerance (SIHFT) offers a flexible and cost-effective alternative. This work evaluates compiler-based SIHFT techniques that provide automated, transparent protection, achieving hardware-level resilience through software-only transformations with minimal user intervention.
System-on-chip security architecture is a critical, complex, and time-consuming activity, consuming months of effort. Furthermore, the architectural design can include subtle errors that compromise the security of the entire system. In this article, we develop a security engine infrastructure, SEnTry , for systematically creating security architectures for protecting SoC designs against a variety of security subversions. SEnTry provides a plug-and-play, configurable subsystem composed of custom IPs that can be integrated into the platform to derive different security primitives. We develop an instance of SEnTry for supply-chain attacks. We discuss the spectrum of challenges involved in developing a unified architecture for systematic protection against the variety of attacks involved and the SEnTry approach to addressing them. We provide several case studies to demonstrate SEnTry design and perform extensive experiments to evaluate its overhead on multiple ASIC technologies. Our experiments suggest that SEnTry incurs minimal overhead in area and power consumption.
As global hardware manufacturing expands and the need to meet time-to-market demands grows, companies increasingly depend on the zero-trust model to manage most of the design process for Integrated Circuits (ICs). Consequently, valuable hardware intellectual property (IP) becomes vulnerable to piracy, cloning, reverse engineering (RE), and unauthorized modifications throughout the global IC supply chain. Current security solutions are designed to safeguard the designs and protect sensitive information throughout the design flow. In this study, we present a thorough evaluation of various IP countermeasure techniques, including Logic Locking, State Space Transformation, Fine-grain Hardware Redaction, and NoC Routing Table Configuration, described in the existing literature. Inspired by cybersecurity competitions and community evaluation efforts, we designed a collaborative benchmarking initiative to evaluate these techniques on open-source benchmark designs, unveil the gaps and limitations of each technique, and discover crucial paths for future exploration. Through a retrospective analysis of this initiative, the insights we gained can significantly contribute to improving countermeasure techniques in the broad domain of hardware security and trust.
The spread of mosquito-borne diseases is accelerating owing to several factors, including human-made ones. In response, scientists are developing various types of baits, including organic, chemical, and electronic, to lure mosquitoes and monitor, control, and kill them. These baits function by replicating stimuli that attract mosquitoes, including human breath, body heat, color, and mosquito wingbeat sounds. Wingbeat sound baits generated from the wings of female mosquitoes are particularly effective in attracting males. Carbon dioxide is a potent attractant and the closest human mimic among the available mimics. Human metabolism, pregnancy, skin temperature, microbiomes, and other factors all play significant roles in the attractiveness of humans to mosquitoes. Effective bait design requires a comprehensive understanding of mosquito behavior, including feeding, mating, and oviposition patterns. Lab, semifield, and field experimental studies allow researchers to isolate behavioral responses to specific stimuli before evaluating their effectiveness under more realistic ecological conditions. Optimizing the baiting system power maximizes efficiency and success in baiting mosquitoes. The future of mosquito bait lies in automating and digital twinning of baiting systems and in prioritizing human and environmental safety.

By utilizing virtual reality (VR), the platform provides a hands-on experience for users to explore and comprehend cyber-attack implications. User studies were conducted to evaluate the effectiveness of the platform, revealing statistically significant improvements in participants’ knowledge, engagement, and self-efficacy related to automotive security. The findings underscore the potential of immersive learning tools in automotive security education, with IVE demonstrating a substantial impact on participants’ comprehension and interest in automotive security.
Multitenant systems have become essential for delivering scalable, flexible, and cost-effective computing services, mainly due to the widespread adoption of cloud computing. In these systems, the computing infrastructure is shared among multiple users, which helps to optimize resource usage and lower operational costs. However, this shared approach among mutually distrusting users creates a unique adversarial environment. This paper comprehensively reviews the security issues associated with these systems, highlighting how their core architectural features-resource sharing, customizability, and isolation-combined with their unique adversarial environment can introduce new vulnerabilities or amplify existing ones.We categorize common attack vectors based on adversarial roles, entry points, and their impact on the system. In addition, we review the current literature on security defenses and organize countermeasures into two main categories: detection and mitigation. Lastly, we outline emerging research directions and identify key challenges in improving the security of multitenant environments.
Modern system-on-chip (SoC) designs are increasingly vulnerable to supply chain threats such as counterfeiting, overproduction, and reverse engineering, leading to financial losses, intellectual property (IP) theft, and compromised system integrity. Existing security engines, while effective in principle, typically rely on microcontroller-based architectures that incur significant area and power overhead, making them impractical for resource-constrained devices. In this article, we present a minimally configured security engine (MCSE), a lightweight, modular, configurable security engine designed to address the most critical supply-chain threats with minimal resource consumption. We introduce the notion of minimum security, a baseline set of protection features necessary to secure SoCs under strict area and power constraints, and demonstrate how MCSE can be tailored to meet diverse system requirements. We validate our architecture through implementation on multiple ASIC technology nodes, showing favorable tradeoffs between security capability, area, and power. Our results establish MCSE as a compelling solution for integrating supply chain protection into low-power and area-sensitive SoC designs.

Understanding automotive security becomes more significant as the probability of the average person interacting with an autonomous vehicle accelerates— Yet, only a small group of specialized experts understands the nuances of security in automotive systems. With this paper, we address this knowledge gap by developing an exploration platform that provides hands-on experience with wheel speed sensors (WSS) and their security weaknesses. Unlike previous research that based such exploration platforms solely on hardware or exclusively on virtual reality, this platform combines the two. Users, from students to industry professionals, may experience different wheel speed sensor attacks from the attacker and victim perspectives in a virtual environment built with Unity, a game development engine. The experience uses data from a wheel speed sensor model and a solenoid attacker module coded with Arduino. We describe the development process for this wheel speed sensor exploration platform and demonstrate how it might be used to understand different attack vectors, including a new spoofing attack developed with the platform that allows the attacker to accurately control the wheel speed with a PID controller and spoofed magnetic pulses. The platform serves as a medium for researchers to create and defend against new attacks and as an educational resource to expand knowledge in the automotive security field.

Building on these findings, we outline key technical implications and emerging trends, highlight current challenges, and propose future research directions to advance healthcare IoT and its digital twin applications.
5G communication technology has become a vital component in a wide range of applications due to its unique advantages such as high data rate and low latency. While much of the existing research has focused on optimizing its efficiency and performance, security considerations have not received comparable attention, potentially leaving critical vulnerabilities unexplored. In this work, we investigate the vulnerability of 5G systems to bit-flipping attacks, which is an integrity attack where an adversary intercepts 5G network traffic and modifies specific fields of an encrypted message without decryption, thus mutating the message while remaining valid to the receiver. Notably, these attacks do not require the attacker to know the plaintext, and only the semantic meaning or position of certain fields would be enough to effect targeted modifications. We conduct our analysis on OpenAirInterface (OAI), an open-source 5G platform that follows the 3GPP Technical Specifications, to rigorously test the real-world feasibility and impact of bit-flipping attacks under current 5G encryption mechanisms. Finally, we propose a keystream-based shuffling defense mechanism to mitigate the effect of such attacks by raising the difficulty of manipulating specific encrypted fields, while introducing no additional communication overhead compared to the NAS Integrity Algorithm (NIA) in 5G. Our findings reveal that enhancements to 5G security are needed to better protect against attacks that alter data during transmission at the network level.
Vehicular safety is essential to protect drivers, passengers, and pedestrians from accidents caused by human error, environmental factors, or mechanical failures.

Such a system is crucial for advancing vehicular safety, building public trust, and promoting the adoption of autonomous vehicles.
