True Random-Bit Generation Using a Continuous-Time Chaotic Oscillator
نویسنده
چکیده
This paper presents a true random-bit generation through a continuous-time chaotic oscillator, which provides automatically chaotic signals and is fully implemented on 0.18 CMOS standard technology. Chaotic dynamics of the oscillator are exhibited in terms of chaotic strange attractor in phase-space domain. In order to achieve true-random property, a simple designed of post-processing method is utilized. Finally, the quality of randomness is analyzed through 1,000,000 binary sequences which are verified by statistical test methods and NIST standard tests suite. The proposed system has offered a cost-effective and a compact random-bit generator for computer security applications.

متن کاملSpread Spectrum using Chaotic System
Chaotic signal helps in a secure communication, by generating wideband spectra of random sequences. Chaotic signal has the property of synchronization; data are transmitted from one location to another by mapping bit sequences to symbols, and symbols to sample functions of analog waveforms. The synchronization between two digital chaotic oscillators, serving as a transmitterreceiver scheme, is ...

In this paper, we discuss fundamentals for the design of a source of chaotic signals based on a blocking oscillator circuit. We study a modification of a well-known circuit of blocking oscillator which leads to the onset of chaotic oscillations. The output signal of such chaotic oscillator is a series of short term pulses characterized by chaotic fluctuations of time intervals between pulses. S...

Introduction: Random number generation is indispensable in cryptography, scientific computing and stochastic computing. In cryptography, the quality of randomness of the generator is critical for security [1]. The pseudo-RNG generates sequences using a deterministic algorithm, so the sequence inevitably repeats and becomes predictable. A true RNG is nondeterministic and unpredictable, often rel...
متن کاملRandom Bit Generator Based on Non-Autonomous Chaotic Systems
In the last decade, a very interesting relationship between cryptography and chaos theory was developed. As a result of this close relationship, several chaos-based cryptosystems, especially using autonomous chaotic dynamical systems, have been put forward. However, this chapter presents a novel Chaotic Random Bit Generator (CRBG), which is based on the Poincaré map of a non-autonomous dynamica...
