True randomness can't be left to chance. Adopting improved entropy sources that feed into good deterministic random bit generators, together with rigorous estimation of available entropy, will help achieve the guarantees promised by cryptography to protect sensitive information.
In this paper an improved chaotic switching algorithm based on modified Lozi system is applied. Generally speaking, the main advantage of the switched encrypted model is its robustness to the noise, while the main drawback is the slow processing speed. In this article we propose to gain model productivity by adjusting parameter in Lozi chaotic generator. Chaos generator is sensitive to any structure,...
Random number generator (RNG) is widely used in cryptographic system as the cryptographic keys generator. These keys are the most important component in the system since the security of the cryptographic system relies entirely on its quality. As digital circuit becomes faster and smaller, some of the desired properties a RNG should have are low-power and good statistical quality. This paper presents...
Pseudo random number generators (PRNG) play a key role in various security and cryptographic applications where the performance of these applications is directly related to the quality of generated random numbers. The design of such random number generators is a challenging task. In this paper, we propose an application of Hopfield Neural Networks (HNN) as pseudo random number generator. This is done...
In this paper, an enhanced and provably secure hybrid random number generator (Hybrid RNG) for generating the cryptographic keys in a cryptosystem is designed. These keys are the most crucial component in this system as the security of the most cryptosystem lies entirely on it. Therefore, a mechanism to generate this key is presented and the generation platform must be strong and cryptographic secure...
