Block cipher has been one of the most reliable options by which data security is achieved.
The strength of block cipher against various attacks is purely dependent on its confusion …

Early cancer identification is regarded as a challenging problem in cancer prevention for the
healthcare community. In addition, ensuring privacy-preserving healthcare data becomes …

In modern technological era image encryption has become an attractive and interesting field
for researchers. They work for improving the security of image data from unauthorized …

In this paper, a noise-resistant image encryption scheme is proposed. We have used a cubic-
logistic map, Discrete Wavelet Transform (DWT), and bit-plane extraction method to encrypt …

Symmetric encryption has been considered as one of the essential means of ensuring
security of end to end communication. The robustness and strength of modern day block …

In the transmission of medical images, if the image is not processed, it is very likely to leak
data and personal privacy, resulting in unpredictable consequences. Traditional encryption …

In the Internet of Things (IoT), a lot of constrained devices are interconnected. The data
collected from those devices can be the target of cyberattacks. In this paper, a lightweight …

This paper presents a hybrid method for the construction of cryptographically strong bijective
substitution-boxes by utilizing the merits of chaotic map and algebraic groups. The hybrid …

Key-dependent dynamic substitution boxes (S-boxes) are important building blocks of many
image encryption schemes, in which a session key controls the construction of dynamic S …

The success of AES encryption standard created challenges for the cryptographers to
construct strong substitution-boxes using different underlying approaches. It is because they …
