Abstract
With the rapidly increasing rate of using online services and social media websites, cybercriminals have caused a great deterioration in the network security with enormous undesired consequences. Encryption techniques may be utilized to achieve data robustness and security in digital multimedia communica-tion systems. From this perspective, this paper presents an optical ciphering fra-mework using Double Random Phase Encoding (DRPE) for efficient and secure transmission of Three-Dimensional Videos (3DVs). Firstly, in the DRPE-based 3DV cybersecurity framework proposed in the paper, an optical emitter converts each frame of the transmitted 3DV into an optical signal. Then, the DRPE tech-nique encrypts the obtained optical signal using two kinds of phase modulation in the time and frequency domains. Lastly, a Charge Coupled Device (CCD) digital camera converts, upon detection, the optical cipher frames to digital format. The proposed DRPE-based 3DV cybersecurity framework is examined and investi-gated through visual inspection and various security statistical metrics. Experi-ments and analysis show that the proposed DRPE-based 3DV cybersecurity framework is secure and effective to mitigate different multimedia attacks.
