Face recognition is a relatively common method humans use to confirm their identity.
Protecting the safe transmission of face images has become a hot issue. This paper …

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 …

This paper presents a color image cryptosystem based on dynamic DNA encryption and
chaos. The color plain image is firstly decomposed into red, green and blue components …

Memristors can be employed to mimic biological neural synapses or to describe
electromagnetic induction effects. To exhibit the threshold effect of electromagnetic …

Continuous memristor has been widely used in chaotic oscillating circuits and neuromorphic
computing systems. However, discrete memristor and its coupling discrete map have not …

This paper proposes a new hybrid chaotic map and a different way of using optimization
technique to improve the performance of encryption algorithms. Compared to other chaotic …

Based on compressive sensing and double random encryption strategy, a novel color image
compression and encryption scheme is proposed in this paper. The architecture of …

Audio information strongly correlates in adjacent times, and the data type of the audio is
float, so the traditional encryption algorithms for the image are unsuitable for audio …

It is well known that chaos is unpredictability and sensitivity to initial values and parameters.
It is a best choice for cryptography application. However, the existing chaotic cryptography …
