Due to the onset of the Covid-19 pandemic, people are compelled to maintain social distance in all spheres of life, forcing people to adopt virtual mode of activity. Usage of social media and other internet activity has shot up in this period, and consequently, cybercrimes have also increased. If cybercrimes are reported, computer forensics analysts will examine the concerned website, online forum, or social media to find meticulous details about the cybercrime. But webpage content seen on the day may not be available on the next day. The contents of the webpage, which is the subject of crime, will be deleted or withdrawn, or deactivated to destroy evidence to escape from legal proceedings. The victims usually produce a screenshot of the webpage or image or video as a piece of evidence. But there is a distinct possibility of manipulating the offensive materials and it may not be considered a valid piece of evidence before the court of law. Such a scenario requires a forensic technique that should acquire the content of the webpage before it is removed from web site to maintain the authenticity of captured data. So, we are proposing an automated system for the forensic acquisition of a website that will effectively capture all content from the live website and make it useful for forensic investigation and may be produced before the court as valid evidence of cybercrime. © 2022 IEEE.

Fire presents a serious risk to life and can be triggered by various factors across different environments. In some areas, the absence of fire detection systems is often due to the high initial investment costs, particularly when the need for such systems is temporary. To tackle this issue, we propose a portable fire detection system as an innovative solution. This system features sensors that monitor for fire outbreaks and alert authorities. A key challenge to its adoption is the limitation on power consumption. To mitigate this, we have developed a custom microcontroller board designed for a low-power, battery-operated portable fire detection system, which has been field-tested. A thorough power analysis of the system has been conducted, revealing a sensor battery life of 62 days. This paper details the design features and presents the findings of the power analysis performed.

The realization of certain computational problems using quantum mechanics opened up interesting new possibilities which may be better and beyond the scope of classical supercomputers. Simulation of quantum circuits on classical computers is necessary to analyze the properties of superposition and entanglement. Here, we used the SDKs of optimized libraries and tools of cuQuantum for accelerating quantum computing workflows on FP64 and TF32 based accelerated system for performance analysis. In this paper, the performance of quantum algorithms (Shor's algorithm, Quantum Fourier Transformation, and Sycamore circuit), implemented by the CIRQ simulator, is analyzed on the PARAM HPC-AI system. Execution time and relative speed up for CPU only and accelerators having multiple precision capability enabled run is discussed in detail on PARAM Siddhi-AI system. The graphs are plotted to give a real-Time analysis of the quantum circuit algorithms with the increase in the number of qubits. For Shor's algorithm, Quantum Fourier Transformation, and Sycamore circuit, the maximum speed up, between CPU only and GPU enabled run, is observed as 143x, 115x, and 104x for 30, 32, and 32 qubits respectively. © 2022 IEEE.

Keystroke dynamics is considered as a supporting factor of authentication. Especially in the static keystroke dynamics, the user is identified by using the timing featured, which is captured while the user enters the login ID and password. To achieve this, the user profile needs to be created with timing features. However, in a scenario like a change of password where nearly no keystroke timing data is available, non-conventional features may be helpful. This article focuses on using non-conventional features such as NumLock key, Shift key, CapsLock key, etc for identifying users during a change of password. The paper also details how to capture the non-conventional features in static keystroke dynamics and build a model that can be used in the change of nassword. © 2023 IEEE.

Natural Language Processing (NLP) is a specific field within artificial intelligence (AI) that focuses on enabling computers to understand spoken and written language in a manner similar to humans. Its practical applications include facilitating everyday activities such as texting, emailing, and cross-language communication. The demand for intelligent systems capable of reading text, listening to voice memos, and engaging in natural language conversations, even in languages like Hindi, has significantly increased in recent years. This paper presents a random clausal hindi sentence generator, which generates simple, compound, and complex sentences. This tool is particularly useful for students studying on online platforms as it provides a variety of exercises to practice on and learn about clauses. The sentence generation process begins with the generation of simple sentences and gradually progresses to compound and complex sentences. The method employs approximately one hundred verbs to introduce randomness, along with three to four conjunctions and objects that are closely associated with the verbs. This approach ensures that the generated sentences are both syntactically and semantically meaningful. © 2024, IFIP International Federation for Information Processing.

Active Voltage Balancing of Series-Connected SiC MOSFETs During Body-Diode Turn-Off Using an Active Gate Driver

引用

IEEE Transactions on Power Electronics 2025年第8期40卷 10609-10622页

The series connection of fast-switching SiC MOSFETs presents a promising approach to enhance the efficiency, compactness, and simplicity of Medium Voltage (MV) power converters. However, managing voltage imbalances during the turn-off of MOSFETs and their body diodes introduces significant challenges. While existing literature covers passive and active voltage balancing strategies for switch turn-off (e.g., MOSFETs/IGBTs), the issue of uneven voltage distribution during body diode turn-off remains largely unexplored. This gap limits the widespread adoption of series-connected devices in MV power converters, as achieving reliable performance with minimal additional components and low switching losses remains difficult. This article presents an Active Voltage Balancing technique for handling body diode turn-off events by regulating the gate charge of parallel MOSFETs during voltage rise transients in the closedloop using Active Gate Drivers (AGD). This approach ensures uniform voltage distribution among the body diodes of seriesconnected MOSFETs. A comprehensive analysis and modelling of gate charge control during voltage transients is presented. The proposed method is experimentally validated on two seriesconnected SiC MOSFETs operating in buck mode (DC-DC) and half-bridge inverter mode (DC-AC) at a 1.5 kV DC bus voltage, with switching frequencies up to 40 kHz. © 1986-2012 IEEE.

This paper outlines the design and implementation of a test vector generation module for the lightweight block ciphers PRESENT, CLEFIA, and the SPONGENT hash function for use in cryptographic module validation. These algorithms are part of the ISO/IEC 29192-2: 2012 standard and ISO/IEC 29192-5: 2016, respectively. The test vector generation module generates test vectors for being fed to the IUT (Implementation Under Test) for validating the algorithms as per the validation methods described in the ISO/IEC 18367:2016(E) standard for block ciphers and hash functions that can operate in different modes of operation. The implementation of test vector generation modules for these algorithms is done in the C programming language, which is described in this paper. These generated vectors can be used as reference test vectors in CMVT (Crypto Module Validation Testing) labs for validating the cryptographic modules that implement these cryptographic algorithms. © 2023 IEEE.

The increased demand for computation and storage needs in recent days cannot be catered fully by single environment, be it public clouds or private clouds or edge nodes, as the request specification are heterogeneous in nature. This led to the need for integrated environment comprising heterogeneous service providers and execution environments with varied components that constitute the integrated environment to cater service requirements. This leads to security requirements such trust management, reliability, authentication and authorization issues. A Zero trust framework within the integrated environment is proposed to address the security challenges by adaptive access control, policy enforcement. Along with the Zero trust framework, a smart gateway between IoT devices and edge nodes is proposed to handle the heterogeneity in protocols, applications and platforms upon which the applications are built. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
