As digital products communicate over public networks, digital image security becomes
essential. Despite advancements in encryption technology, protecting data from secure …

The digital images are widely captured, transmitted, and stored by limited resource devices.
Those devices need lightweight encryption (LWE) techniques to protect secret and personal …

Modern cryptographic systems use substitution boxes (S-boxes) throughout the encryption
process to enhance the security of the plaintext. The integrity of the communication process …

In the new era of cryptography, Substitution Boxes (S-Boxes) are very important to raise
confusion in cipher text and the security of encryption directly depends on the algebraic …

In the modern block cipher, the substitution box (S-box) is a nonlinear constituent that plays
a substantial role to create the confusion in ciphertext. S-boxes with low value of differential …

This work introduces a novel image encryption algorithm specifically designed for the
protection of color medical images, particularly crucial in the era of cloud storage, where …

As a common nonlinear component in block cipher, S-box plays a role of confusion and
determines the security strength of the whole block cipher algorithm. How to generate a high …

This article presents a cryptographic encryption standard whose model is based on Serpent
presented by Eli Biham, Ross Anderson, and Lars Knudsen. The modification lies in the …

Privacy and confidentiality are essential for any patient-related information, including
medical images. In this paper, a novel image encryption technique for medical images is …

A substitution box (S-box) in data encryption is a non-linear tool that conducts substitution to
assure the overall security of the system. S-box is the most important part of the block cipher …
