The suggested lightweight video encryption strategy offers a promising method for safeguarding multimedia data in cyberspace. The proposed strategy is based on a hybrid chaotic map and DNA encryption. Due to the fewer dimensions of the chaotic map, it can be adapted to secure real-time data generated using closed-circuit television and other Wireless sensors network tools. The strategy provides a strong level of security and resistance against different attacks by utilizing advanced cryptographic techniques including hybrid chaotic systems and DNA encryption. The proposed work is decently compared with other contemporary competing encryption schemes which shows that the proposed one can be adapted for the encryption of videos in lightweight applications. The thorough assessment using simulation results and statistical experiments highlights the practical applicability and efficiency of the proposed encryption technique.
