In recent years, a large amount of work on chaos-based cryptosystems have been
published. However, many of the proposed schemes fail to explain or do not possess a …

Recent researches of image encryption algorithms have been increasingly based on chaotic
systems, but the drawbacks of small key space and weak security in one-dimensional …

Many studies show the possibility of transmitting messages in a protected and covert
manner using a noise-like chaotic waveform as a carrier. Among popular chaotic …

A large number of analog chaos-based secure communication systems have been
proposed since the early 1990s exploiting the technique of chaos synchronization. A brief …

The need for image encryption is constantly on the rise and has led to the emergence of
many techniques in literature. In recent years, many chaos‐based encryption techniques …

Recently Bu and Wang [Bu S, Wang BH. Chaos, Solitons & Fractals 2004; 19 (4): 919–24]
proposed a simple modulation method aiming to improve the security of chaos-based …

In this paper, we propose a simple and efficient crypto-system based on a chaotic time delay
model. It consists of two steps: the first one assures the transmitter/receiver synchronization …

As a powerful cryptanalysis tool, the method of return-map attacks can be used to extract
secret messages masked by chaos in secure communication schemes. Recently, a simple …

In cryptography, the property of randomness in pseudo-random generators is very important
to avoid any pattern in output sequences, to provide security against attacks, privacy and …

We investigate the synchronization in coupled time delayed semiconductor laser models
without and under the influence of external noise sources. The synchronization and its …
