One of the fastest-growing industries in recent years has been e-Healthcare. Many
cyberattacks and threats against patient confidentiality exist in electronic health records …

Traditionally, keys are generated using the hash value of the given image in the image
cryptography to boost the security effects. The keys have been sent to the concerned …

A novel color image encryption based on permutation and bit-wise exclusive OR (XOR)
operation is introduced in this work. The main objective of the proposed scheme is to …

In this paper, we have proposed a novel method CloudSec. It is a lightweight and agile
image encryption method that combines a hashing function, multi-wing chaotic mapping …

This paper proposes a four-dimensional hyperchaotic system to overcome the defect of
weak encryption effect due to the simple complexity of low-dimensional chaotic systems in …

The smart healthcare system is one of the Internet of Things‐based applications that are
increasingly used nowadays. One of the requirements of this system is privacy‐preserving …

In this paper, a security analysis of Image Encryption Algorithm based on Cellular Automata
and Chaotic Skew Tent Map (IEA-CACSTM) is presented. The security of IEA-CACSTM has …

As data centers continue to grow in size and importance, protecting the security of data
during connectivity becomes critical. In this paper, we propose a deoxyribonucleic acid …

Blockchain-based Internet of Things (IoT) applications require flexible, fast, and low-power
hashing hardware to ensure IoT data integrity and maintain blockchain network …

With the increasing demand for image transmission in various fields including medical,
