摘要

The rapid advancement of network technologies and multimedia applications across various sectors, including military and industry, underscores the importance of safeguarding digital data, especially videos and images. Encryption of video is essential in making sensitive content into a completely unrecognizable form. However, traditional methods of encryption face severe difficulties in terms of resolution loss, high computational complexity, and low optimization, which makes the technique less practical and authentic. Addressing such issues, this paper describes the Opposition Lotus Effect-Elliptic Curve Cryptography (OLE-ECC) algorithm. The integration of elliptic curve cryptography with the Opposition Lotus Effect Algorithm enhances video encryption by generating secure key pairs resistant to cryptographic attacks. The video data is encrypted using generated keys by dividing the video stream into segments and applying encryption algorithms to each. This process involves four key phases such as channel segmentation, channel scrambling, generation of key streams from the logistic graph, and channel propagation. The use of multi-equation multi-key cryptography increases the safety of video data significantly while encrypted because it involves applying a number of mathematical equations along with multiple keys. This technique effectively manages the encryption of dynamically generated video files and allows the possibility of encrypting different segments of the video with different keys, making it efficient in performance for real-time streaming applications. For video decryption, the encrypted video is sent over the communication channel, the decryption process includes bit-wise exclusion, rearrangement of channel blocks, and pixel reordering, which increases the reliability of the recovered video frames. Furthermore, the program for revealing, combined with XOR operations, allows the recovery of hidden pixels without loss of quality. Message Authorization Codes and digital signatures also strengthen the integrity of the encrypted video. Using Message Authorization Codes to establish the fact that the information is not modified, this model allows for the detection of unauthorized modifications of the data. An experimental study has been conducted to assess the efficiency of the proposed OLE-ECC method with the traditional methods. The experimental evaluation results showed that the developed OLE-ECC model had higher performance rates with a reduced encryption time of 4.49 s and decryption times of 0.11 s to traditional solutions, and a higher security rate of 98.5% is achieved compared to the traditional method. Overall, the OLE-ECC algorithm provides a more reliable video encryption method than other approaches, eliminating their drawbacks and ensuring improved security and efficiency in the protection of video content.
