Opto-Video Encryption Based on Logistic Adjusted Sine map in FrFT

Abstract

In the last few years, videos became the most common form of information transmitted over the internet, and a lot of the traffic is confidential and must be protected and delivered safely to its intended users. This introduces the challenges of presenting encryption systems that can encode videos securely and efficiently at the same time. This paper presents an efficient opto-video encryption system using Logistic Adjusted Sine map (LASM) in the Fractional Fourier Transform (FrFT). In the presented opto-video LASM-based FrFT scheme, the encoded video is split into distinct frames and transformed into optical signals utilizing an optical supply. Each of the developed optical video frames is ciphered by utilizing the LASM in optical FrFT system using two-phase modulation forms on the video frame, the first in the time-domain and the second in the FrFT domain. In the end, the ciphervideo frame is spotted utilizing a CCD digital camera and transformed into a digital structure that can be managed using a computer. We test the proposed opto-video LASM-based FrFT scheme using various security tools. The outcomes demonstrate that the presented scheme can effectively encrypt and decrypt video signals. In addition, it encrypts videos with a high level of encryption quality without sacrificing its resistance to noise immunity. Finally, the test outcomes demonstrate that the presented scheme is immune to known attacks.
