This paper presents an improved image encryption algorithm using Haar wavelet packets
decomposition and four chaotic maps. For the wavelet packets scrambling we propose a …

This paper presents an efficient encryption algorithm based on 3 chaotic systems. Initially,
the Bogdanov chaotic system is used to scramble the original image, in order to complicate …

Dynamical degradation is a known problem in the computer simulation of chaotic systems.
Data type limitations, sampling, and rounding errors give rise to the periodic behavior. In …

This paper proposes an encryption algorithm for speech signals based on two chaotic
systems: Arnold 3D Map and Tent Map. The algorithm obtains the same results for audio …

This paper presents a fast encryption algorithm for speech signals using the Arnold 3D and
the Tent Map chaotic transformations. Arnold 3D chaotic map is known for the property of …

The steps of the new enciphering algorithm are concisely given. Its performance is validated
through MATLAB simulations, using well-known metrics as PSNR, NPCR or UACI. The …
