Chaos is known as a natural candidate for cryptography applications owing to its properties
such as unpredictability and initial state sensitivity. However, certain chaos-based …

Image encryption provides confidentiality to images by transforming them into
unrecognizable forms that resemble white noise. Digital chaos is one of the areas used to …

In this paper, we propose a new two-dimensional Sine improved Logistic iterative chaotic
map with infinite collapse (ICMIC) modulation map (2D-SLIM) based on the improved two …

For a linear image encryption system, it is vulnerable to the chosen-plaintext attack. To
overcome the weakness and reduce the correlation among pixels of the encryption image …

In this paper, we present a robust and secure watermarking approach using transform
domain techniques for tele-health applications. The patient report/identity is embedding into …

Image encryption protects visual information by transforming images into an
incomprehensible form. Chaotic systems are used to design image ciphers due to properties …

Most of the image encryption algorithms are the private-key cryptosystem, in which the
encryption process and the decryption process employ the same keys. To enhance the …

Image encryption is an efficient visual technology to protect private images. This paper
develops an image encryption algorithm utilizing the principles of the Josephus problem and …

In the traditional image encryption systems, the permutation-diffusion operation is often
conducted in two essentially separable or independent steps, which appears not only to be …

Nowadays, the images are transferred through open channels that are subject to potential
attacks, so the exchange of image data requires additional security in many fields, such as …
