WIP: The Feasibility of High-performance Message Authentication in Automotive Ethernet Networks
(2023-02-27)Modern vehicles are increasingly connected systems that expose a wide variety of security risks to their users. Message authentication prevents entire classes of these attacks, such as message spoofing and electronic control ... -
Understanding the Security of Linux eBPF Subsystem
(ACM, 2023-08-24)Linux eBPF allows a userspace application to execute code inside the Linux kernel without modifying the kernel code or inserting a kernel module. An in-kernel eBPF verifier preverifies any untrusted eBPF bytecode before ... -
Series FACTS Devices for Increasing Resiliency in Severe Weather Conditions
(MDPI, 2023-08-08)Severe weather conditions are low-probability, high-impact events that affect grid operations. The majority of power outages are caused by severe weather conditions. Grid resiliency to weather events can be enhanced by ... -
New highly efficient high-breakdown estimator of multivariate scatter and location for elliptical distributions
(Wiley, 2023-04)High-breakdown-point estimators of multivariate location and shape matrices, such as the MM-SHR with smoothed hard rejection and the Rocke S-estimator, are generally designed to have high efficiency for Gaussian data. ... -
Automatic elimination of phase aberrations in digital holography based on Gaussian 1o-criterion and histogram segmentation
(Optica Publishing Group, 2023-04)We propose a numerical and automatic quadratic phase aberration elimination method in digital holography for phase-contrast imaging. A histogram segmentation method based on Gaussian 1 sigma-criterion is used to obtain the ... -
Eunomia: Enabling User-Specified Fine-Grained Search in Symbolically Executing WebAssembly Binaries
(ACM, 2023-07-12)Although existing techniques have proposed automated approaches to alleviate the path explosion problem of symbolic execution, users still need to optimize symbolic execution by applying various searching strategies ... -
Isotropic Two-Dimensional Differentiation Based on Dual Dynamic Volume Holograms
(MDPI, 2023-07-17)We study the use of two dynamic thick holograms to realize isotropic two-dimensional (2D) differentiation under Bragg diffraction. Acousto-optic modulators (AOMs) are used as dynamic volume holograms. Using a single volume ... -
Write-Light Cache for Energy Harvesting Systems
(ACM, 2023-06-17)Energy harvesting system has huge potential to enable battery-less Internet of Things (IoT) services. However, it has been designed without a cache due to the difficulty of crash consistency guarantee, limiting its ... -
A Procrastinating Control-Flow Integrity Framework for Periodic Real-Time Systems
(ACM, 2023-06-07)Connected embedded systems and cyber-physical systems exhibit larger attack surface than isolated ones. Control-flow integrity (CFI) is a set of techniques to prevent attackers from redirecting program control-flow and ... -
MS-PTP: Protecting Network Timing from Byzantine Attacks
(ACM, 2023-05-29)Time-sensitive applications, such as 5G and IoT, are imposing increasingly stringent security and reliability requirements on network time synchronization. Precision time protocol (PTP) is a de facto solution to achieve ... -
Effect of Power Conversion Efficiency of the RF Energy Harvester on the Security and Data Rate of the Self-Sustainable IoT Devices
(ACM, 2023-06-14)This paper presents a study on the impact of the power conversion efficiency (PCE) of RF energy harvesters on the performance of wireless Internet-of-Things (IoT) devices including the sampling rate and data security. An ... -
Recent progress of Ga2O3 power technology: large-area devices, packaging and applications
(IOP Publishing, 2023-06)Benefitted from progress on the large-diameter Ga2O3 wafers and Ga2O3 processing techniques, the Ga2O3 power device technology has witnessed fast advances toward power electronics applications. Recently, reports on large-area ... -
