Spread spectrum (SS) technology is a data transfer technique designed to overcome the interference problems associated with narrow-band very high frequency and ultra high frequency Data transfer systems. Spread spectrum communication is used to reduce jamming of communication signal and provides a highly secure communication. In this paper we specifies the Field Programmable Gate Array (FPGA) i...

We present a new Design for the generation of Advanced encryption of (bit) data. The Design opted to obtain this encrypted data is RM-PRNG. This design also enhances the statistical properties of a chaos-based logistic map pseudo random number generator (PRNG) and extends the system period length. The reseeding method removes the short periods of the digitized logistic map and the mixing method...

In this paper, a new fractional-order seed chaotic generator is designed to solve the problem of complex operations single low-dimensional systems and simple high-dimensional systems. The system generated proven have better performance using Lyapunov exponential differential calculus, approximate entropy, 0–1 test other indicators. On basis, “multiple squares nested body scrambling (MSNBS)” mod...

 There have been strong links between chaotic theory and cryptographic for the last three decades. The characterization of behaviors Chaotic system, such as: highly responsive to initial states, mixing attributes, deterministic existence, often unable predict long-term returns, allows researchers improve security cryptography systems. As a result, there are growing numbers experiments that...

Abstract In an isolated system, the time evolution of a given observable in Heisenberg picture can be efficiently represented Krylov space. this representation, initial operator becomes increasingly complex as goes by, feature that quantified by complexity. We introduce fundamental and universal limit to growth complexity formulating Robertson uncertainty relation, involving Liouvillian, genera...

In this paper, a new third-order chaotic system which has extremely multistability is constructed by introducing the boosted control of cosine function. comparison with other systems multistability, proposed can spontaneously generate infinitely many coexisting attractors towards two directions phase plane. It indicates output more sequences different amplitudes at same time. This peculiar phys...

One of the widely-used ways in chaos-based cryptography to generate pseudo-random sequences is use least significant bits or digits finite-precision numbers defined by chaotic orbits. In this study, we show that results obtained using such an approach are very prone rounding errors and discretization effects. Thus, it appears generated close random even when parameters correspond non-chaotic os...
