A simple novel method for random number generation is presented, based on a random Raman fiber laser. This laser is built in a half-open cavity scheme, closed on one side by a narrow-linewidth 100 mm fiber Bragg grating. The interaction between the randomly excited lasing modes of this laser, in addition to nonlinear effects such as modulation instability, allow the generation of random bits at rates of up to 540 Gbps with minimal post processing. Evaluation of the resulting bit streams’ randomness by the NIST statistical test suite highlights the importance of evaluating the physical entropy content, as bit sequences generated by this random laser pass all the statistical tests with a significance level of 0.01, despite being generated at more than twice the theoretical entropy generation speed.

“…And the parameter G is the arbitrary value between 7 × 10 12 and 8 × 10 12 , which is accurate to the eighth decimal place, thus the key space KS G =10 8 . Similarly, for the diffusion processes, the map parameters r 1 ∈ [0.5, 0.7] and r 2 ∈ [1.4, 1.8] with a step of 10 −8 , so the key space KS r 1 =2×10 7 and KS r 2 =4×10 7 .…”

“…Hence, the chaotic signal has natural concealment and unpredictability. In virtue of the excellent characteristics, chaos has been applied in almost every industry or trade: physical random bit generation [8], liquid level sensor [9], optical network security [10], intelligent image protection [11], and especially in image encryption field [12]- [14], [17]- [23]. A fast and secure symmetric image encryption scheme employed the 3D chaotic cat map to shuffle the positions of image pixels [12].…”

Cloud servers are very suitable for sharing and storing image data and meanwhile it is confronted with many security and privacy problems. Optical chaos and hardware implementation of image encryption possess distinct superiorities in secret image sharing. Hence, combining the advantages of advanced reduced instruction set computer machine (ARM)-embedded platform Exynos4412 model, together with vertical-cavity surface emitting laser (VCSEL) subject to positive optoelectronic feedback (POEF), a novel color image encryption and transmission system is experimentally realized and appraised. We investigate the dynamic behaviors of the VCSEL and obtain the chaotic output. An analog to digital conversion (ADC) module is utilized for optical chaos data acquisition. The improved gravity model and the double sine map are exploited to encrypt the image, and the encrypted image is securely shared by cloud services. The user can download the encrypted image and decrypt it by the hardware board. The experiment results reveal that the system has an excellent resistance to common attacks. Compared to the numerical simulation, our hardware implementation for such a color image encryption and transmission system is formidable to actualize, but we successfully implemented and tested in a real-world environment. By comparing experimental and simulation results, the consistent results are found. Therefore, in the case of similar encryption effect, the user's information privacy protection in the actual industrial or commercial systems can be securely guaranteed on our hardware platform.

“…Through further combining the three chaotic signals, it can be obtained seven channels of chaotic entropy sources. As a result, seven channel physical random bit sequences can be simultaneously generated [26]. Different from DFB-SLs, vertical-cavity surface-emitting lasers (VCSELs) may support two orthogonal polarization components co-existing in the cavity.…”

We propose and demonstrate experimentally a scheme for simultaneously generating multi-channel broadband chaotic signals based on two unidirectionally coupled weak-resonant-cavity Fabry-Perot laser diodes (WRC-FPLDs) with almost the same mode interval, where one WRC-FPLD is utilized as master WRC-FPLD (M-WRC-FPLD) and the other is used as slave WRC-FPLD (S-WRC-FPLD). Under the optical injection from the M-WRC-FPLD with suitable injection parameters, multiple longitudinal modes of the S-WRC-FPLD can be simultaneously driven into chaotic states, which can provide multi-channel chaotic signals. Via a tunable optical filter, we inspect the performances of 9-channel chaotic signals, the results show that the chaotic bandwidths are within the range of 8~15 GHz for all the 9-channel chaotic signals. Furthermore, the influences of the injection power and frequency detuning on the performances of the chaotic output from one of the channels are also analyzed.
