“…Various physical layer encryption methods, such as quantum key distribution (QKD) [7], optical steganography [8], optical code division multiple access (OCDMA) [9], hardware chaos encryption [10][11][12][13], and digital chaos encryption [14][15][16][17][18][19][20][21][22][23][24], etc., have all made significant contributions to securing data. Zhang et al used an implementation of high-speed QKD in an SiP QKD encoder using a pass-block architecture and a dedicated SiP decoder based on the polarization-based decoy state Bennett-Brassard 1984 protocol [7].…”

In this paper, we propose a camera projection approach to enhance the physical layer security of coherent optical orthogonal frequency division multiplexing (CO-OFDM) systems. The data are converted to the new location by the camera projection module in the encryption system, where the 5D hyperchaotic system provides the keys for the camera projection module. The simulated 16QAM CO-OFDM security system over 80 km SSMF is shown to provide a key space of about 9 × 1090 through the five-dimensional (5D) hyperchaotic system, making it impossible for eavesdroppers to obtain valid information, and the peak-to-average power ratio (PAPR) is reduced by about 0.8 dB.

“…However, for one, with the rapid development of technology, the update speed of the algorithm is faster than ever before [6], [7], [8], [9], [10]. Secondly, due to the two-dimensionality of digital images, the redundancy and strong correlation between adjacent pixels are eye-catching [11], [12], [13], [14], [15]. Therefore, information security is facing severe challenges in network communication, which urges us to study more secure digital image encryption schemes [13], [16], [17], [18], [19].…”

The issue of information security in photonics environment has attracted more and more attention, especially when the secure communication of optical digital images has become a research hotspot. In this paper, we propose a hybrid encryption scheme for color images in the frequency and spatial domains based on double random transform and memristor hyperchaotic system. Firstly, we decompose the color image into RGB channels and then perform fast fourier transform (FFT) to transform the digital image from the spatial domain to the frequency domain. Secondly, two-phase masks are generated using the memristor hyperchaotic system, and the Fresnel diffraction optical transformation method is performed twice for encryption. Thirdly, the transformation from the frequency domain to the spatial domain is completed using inverse fast fourier transform (IFFT). Finally, the image is permuted and diffused using the chaotic sequences to obtain the final cipher image. Double random phase encryption expands the key space, while the combination of spatial and frequency domains improves the resistance to attacks. Based on cryptanalysis theory, we introduce a dynamic key associated with plain image, which can effectively resist plain attack. The experimental results show that the optical digital image encryption scheme has a large key space, excellent comprehensive performance, and can resist common attacks. In addition, we verify the hardware feasibility and ease of implementation of the proposed algorithm in an embedded optical communication network experimental platform. Therefore, our proposed scheme in this paper is a preferred optical digital image secure communication technology scheme with good application prospects.
