In this paper, we introduce Obfus-chat, a novel framework leveraging Generative Pre-trained Transformer (GPT) models to automate the obfuscation process. The proposed framework accepts hardware design netlists and key sizes as inputs, and autonomously generates obfuscated code tailored to enhance security. To evaluate the effectiveness of our approach, we employ the Trust-Hub Obfuscation Benchmark for comparative analysis. We employed SAT attacks to assess the security of the design, along with functional verification procedures to ensure that the obfuscated design remains consistent with the original. Our results demonstrate the efficacy and efficiency of the proposed framework in fortifying hardware IP against potential threats, thus providing a valuable contribution to the field of hardware security.

Despite the fact that the stature of NVD is one of the most significant databases for the latest insights into vulnerabilities, extracting meaningful trends from such a large amount of unstructured data is still challenging without the application of suitable technological methodologies. Previous efforts have mostly concentrated on software vulnerabilities; however, a holistic strategy incorporates approaches for mitigating vulnerabilities, score prediction, and a knowledge-generating system that may extract relevant insights from the Common Weakness Enumeration (CWE) and Common Vulnerability Exchange (CVE) databases is notably absent. As the number of hardware attacks on Internet of Things (IoT) devices continues to rapidly increase, we present the Hardware Vulnerability to Weakness Mapping (HW-V2W-Map) Framework, which is a Machine Learning (ML) framework focusing on hardware vulnerabilities and IoT security. The architecture that we have proposed incorporates an Ontology-driven Storytelling framework, which automates the process of updating the ontology in order to recognize patterns and evolution of vulnerabilities over time and provides approaches for mitigating the vulnerabilities. The repercussions of vulnerabilities can be mitigated as a result of this, and conversely, future exposures can be predicted and prevented. Furthermore, our proposed framework utilized Generative Pre-trained Transformer (GPT) Large Language Models (LLMs) to provide mitigation suggestions.

We wanted to integrate the same technology for the elderly and disabled and in doing so we sought to make an energy efficient, affordable and a reliable system. The voice and touch assisted home automation system uses an Arduino Mega 2560 as the processor. The system builds upon the utilization of an existing smartphone technology where a smartphone application is used, which allows the users to control up to 44 devices in addition of multiple smoke detectors and PIR motion sensors, using Bluetooth technology. Unlike other systems, for the ease of use, the entire system can be launched and controlled via NFC tags. The cost has been kept under USD 30, for the entire construction, thus enabling its use for the masses, with potential to modernize each and every old home. Since the system requires low power to operate, automating homes shall also reduce power usage.

The proposed iterative algorithm conserves the exact structure of the original solution of LDTP Lyapunov functions while approximating them using Krylov iterations. This paper also exhibits how this proposed structure preserving algorithm generates a reduced order LDTP model. For confirming the efficiency and accuracy of this proposed algorithm numerical results are presented herewith this paper.

Additionally, it aims to provide a performance enhancing solution for the physically disabled people to aid in their daily chores, particularly in lifting heavy objects for a longer period of time. The proposed system uses Commercial Off The Shelf (COTS) components such as: Arduino, Myo-ware Muscle Sensor and Linear Actuator. The aim of this paper is to present the design and fabrication of a light weight, controllable, reliable, wearable and low-cost exoskeleton for the human arm. This device has two modes of operation, the rehabilitation purpose and weightlifting for disabled individuals. The paper is particularly designed in line to the context of Bangladesh, affordability is a priority alongside reliability, to increase availability for the masses.
Performance Comparison of Full Adder Cells in 45nm Technology Node

Therefore, a large number of FA cell designs have been innovated, each of them having their respective pros and cons. As a result, it becomes quite necessary to examine the FA cells under a common environment in order to compare their performance parameters which will facilitate IC designers to choose the right FA topology required by the nature of ALU. This paper presents a comparison among 23 different FA cells. Performance comparison of the FAs has been conducted using Cadence design toolkits. The technology node used for the performance analysis and comparison is 45nm.

Smart Transformer Theft Protection and Maintenance Monitoring System

Much of this economic development is fueled by the development of their power generation. Unfortunately, transformer theft is a common scenario in these countries, which is a key impediment in the way of advancement in the power sector. Therefore, to solve this problem, a GSM based transformer theft protection and monitoring system has been developed in order to protect the distribution transformers from thieves. In addition, the system can also monitor the health parameters of a transformer. The system developed in this paper utilizes several sensors such as a magnetic sensor, IR sensors and weight sensors in order to detect nearby person who wants to steal or vandalize the transformer by notifying the incident to the authority via SMS service of the GSM technology. Moreover, the authority can also monitor transformer health parameters such as transformer temperature and oil level.
