Videos contain temporal information, enabling them to capture the dynamic changes of
actions and provide richer visual effects. Traditional video encryption methods involve …

Bit is the most basic unit of a digital image in the spatial domain, and bit-level encryption is
regarded as an important technical means for digital image privacy protection. To address …

In this paper, we use two Fractional-Order Chaotic Systems (FOCS)—one for the sender and
one for the receiver—to determine the optimal synchronisation for a secure communication …

This study introduces a novel symmetric image encryption algorithm that employs a multi-
layered architecture of chaotic maps, incorporating both confusion and diffusion …

Elliptic curve cryptography has gained attention due to its strong resilience against current
cryptanalysis methods. Inspired by the increasing demand for reliable and secure …

Most of the existing spatial domain image encryption techniques suffer from the difficulty of
resisting cryptographic attacks. For this reason, this paper proposes a frequency-domain …

In the Industrial Internet of Things (IIoT), ensuring timely and secure data transmission
between sensors and edge devices is paramount, particularly when dealing with sensitive …

This paper presents a three-dimensional chaotic map with five equilibrium points, which,
unlike the classic Lorenz system, possesses a symmetric four-wing structure. Through …

Optical encryption based on single-pixel imaging (SPI) has made great advances with the
introduction of deep learning. However, the use of deep neural networks usually requires a …

Nowadays, the Internet of Things (IoT) technology has been widely applied in the police
security system. However, with more and more image data that concerns crime scenes …
