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 communication systems. From this perspective, this paper presents an optical ciphering framework 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 technique 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.
