ASIC design protection against reverse engineering during the fabrication process using automatic netlist obfuscation design flow
Fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. In untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious Trojans. Understanding the netlist topology is the ultimate goal of the reverse engineering process. In this paper, we propose...
متن کاملFabrication and Characterization of the Fiber Optical Taper for a Surface Plasmon Resonance Sensor
For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
متن کاملAn Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
متن کاملDesign and Fabrication Process of MTF Phantom CT Scan
Introduction: One of the main steps in the optimization process in diagnostic imaging is the quality control of radiology devices. The usual method of CT scan calibration is used of a phantom. The phantom created a certain weakening for the radiation through which it passes. One of the most suitable methods for quantitative analysis of the resolution and contrast in CT scan im...
متن کاملOptical Imaging of the Motor Cortex in the Brain in Order to Determine the Direction of the Hand Movements Using Functional Near-Infrared Spectroscopy (fNIRS)
Introduction: In recent years, optical imaging has attracted a lot of attention from scholars as a non- aggressive, efficient method for evaluating the activities of the motor cortex in the brain. Functional near-infrared spectroscopy (fNIRS (is a tool showing the hemodynamic changes in a cortical area of the brain according to optical principles. The present study has been de...
