ABSTRACT
Ensuring the security of multimedia content and its applications has evolved into a pivotal responsibility within IoT communication technology. Cryptography stands out as a fundamental technique that offers security and confidentiality, thereby thwarting unauthorized data access. Choosing an appropriate design for an encryption system becomes imperative to guarantee comprehensive security and the preservation of data privacy. This study focuses on IoT-centric CCTV (CCTV) systems, illuminating potential security weaknesses during data transmission and storage. Through experimental assessments, we evaluate these algorithms’ performance and security characteristics, considering factors such as encryption time, and computational efficiency. By providing insights into the strengths and weaknesses of various video encryption methods, this research aids in the implementation of robust security measures for IoT-driven surveillance applications. In this paper, an optimized video encryption algorithm (OVEA) is proposed. In order to validate the effectiveness of the proposed algorithm, a comprehensive set of experiments is conducted. A comparative analysis is carried out against existing encryption methods to do the relative assessment The proposed OVEA algorithm demonstrates reduced encryption time of 0.00356s compared to various existing public key algorithms when applied to video data.
