Protected stored data as well as transfer in this virtual environment have been a significant
thing since this world wide web has been used for information exchange. The need for data …

The internet of things (IoT) revolution has been sparked by the exponential increase in
connected devices caused by recent advances in wireless technology. These embedded …

Wireless visual sensor networks (WVSN) have been widely used to capture images in the
fields of monitoring, intelligent transportation, and reconnaissance in recent years. Because …

Chaotic systems have been widely used in digital image encryption algorithms because of
their characteristics of deterministic randomness, extreme sensitivity to initial values, etc …

In finite precision implementations of chaotic maps all trajectories are eventually periodic.
The goal of this brief is to develop methods for systematic study of effects of finite precision …

Nonlinear maps are usually implemented using finite-precision floating-point formats both in
practical applications and in theoretical investigations. In the digital domain, the size of the …

A new technique for improving the security of a chaotic cryptosystem has been proposed. An
encryption system based on a Skew Tent Map using this technique has been implemented …

In this work, a new technique capable of improving the randomness properties of a chaos-
based cryptosystem has been proposed. This algorithm has been implemented and tested …

A new technique for improving the security of chaos-based stream ciphers has been
proposed and tested experimentally. This technique manages to improve the randomness …

In this paper we have used a surface micromachined capacitive accelerometer in order to
generate seeds that are suitable for secure communications between wireless smart …
