The quality of encryption is dependent on the complexity of the confusion-diffusion pattern
and the quality of the keystream employed. To enhance complexity and randomness, this …

The Internet of Medical Things (IoMT) is a network of healthcare devices such as wearables,
diagnostic equipment, and implantable devices, which are linked to the internet and can …

To enhance the security of image data transmission, and address the weaknesses of
existing image encryption schemes based on chaotic systems, particularly concerning …

This paper proposes a fractional-order memristor-coupled Hindmarsh–Rose neurons model,
which the number and stability of equilibrium points are related to the coupling strength. By …

Due to its amplification effect on the deviation of the initial value, chaotic systems have been
closely integrated with image encryption in the past few years, which inspires the research of …

A novel image encryption algorithm based on hyperchaos and DNA encoding is proposed in
this paper. Unlike the traditional DNA‐based encoding method, a more fine‐grained …

A substitution box (S-box) serves as the nonlinearity component in a symmetric key
encryption scheme; it directly determines the performance and security level of ciphers …

Plethora of image encryption schemes exist in literature based on the construct of magic
square for realizing the purpose of image obfuscation. This magic square carries out the …

Some existing chaotic systems suffer from issues such as period windows, discontinuous
parameter ranges, and dynamical degradation, which seriously limit their application …

To enhance privacy protection for specific regions within an image while preserving its
overall visual integrity, this paper presents a visual encryption algorithm targeting partial …
