A Survey of Lightweight Cryptography for Power-Constrained IoT Devices: Security Challenges and Issues
CRC Press eBooks, pp. 293–313, 2021
DOI Link BibTeX Cited by 6Abstract
As the Internet of Things (IoT) is growing exponentially, the number of data shared between IoT devices is increasing at an exponential rate. Almost all IoT devices are battery concerned devices in which power is very low, and these devices are interconnected and communicated to perform certain tasks, and also to transmit confidential and sensitive data over a communication channel. The IoT now enables power-restricted systems for communication, processing, and communication decisions. In stratified IoT networks, there are many problems and challenges, including protection, cheap power usage in computers, restricted battery size, memory space, high efficiency, and minimal communication network latency. We address in this paper a state-of-the-art lightweight cryptographic algorithm that includes lightweight block ciphers, hash functions, stream ciphers, high-performance systems, and low power-constrained devices and IoT network tools in detail. The lightweight cryptography algorithms are evaluated based on key size, block size, round size, and structure. We also explore the security framework, challenges, and key solutions for the power-constrained device of the IoT system.

Magnetic Resonance Imaging Classification Methods: A Review
Nanoelectronics, Circuits and Communication Systems, pp. 417–427, 2021
BibTeX Cited by 2Abstract
Magnetic resonance imaging (MRI) is one of the most important medical diagnosis methods in the field of computer-aided detection of medical images. The MRI images help to find the presence of abnormal cells or tissues, referred as tumors. Prior to classification, preprocessing of MRI images is performed. These preprocessing operations help to reduce undesired distortions and select only relevant features for further analysis, making the classification technique more accurate and efficient. In this paper, we present various image classification techniques used over MRI images and their performance.

TPA Auditing to Enhance the Privacy and Security in Cloud Systems
Journal of Cyber Security and Mobility, 2021
DOI Link BibTeX Cited by 36Abstract
Over the last decade, many enterprises around the world migrating from traditional infrastructure to cloud resources in order to cut down operational and capital expenditure. With cloud computing, huge amount of data transactions is communicated between cloud consumers and cloud service providers. However, this cloud computing enables surplus security challenges associated to unauthorized access and data breaches. We proposed in this paper a trusted third-party auditor (TPA) model which uses lightweight cryptographic system and lightweight hashing technique to ensure data security and data integrity to audit the cloud users outsourced data from cloud service providers. With our proposed system, we solve the concern of data reliability using data correctness and verification analysis and error recovery analysis. The time complexity of our proposed system is less as compared with other TPA model. Our proposed system also shows resistance against various known cryptanalytic attacks, the performance and extensive compression technique of our proposed system are probably secure and highly proficient.
