A Light Chaotic Encryption Algorithm for Real-Time Video Encryption

With the increasing application of video, security problems caused by video leakage also become more prominent. Due to the randomness, ergodicity, determinism, and sensitivity to initial conditions of chaotic systems, it is possible to generate a large number of uncorrelated pseudo-random chaotic sequences, so chaotic encryption has become an important research direction for video security. This chapter improves on the basis of chaotic encryption algorithm based on logistic mapping and proposes an optimized chaotic encryption algorithm. The algorithm introduces tent mapping, which complements the logistic mapping to achieve superiority, thereby obtaining better performance than the two algorithms. On this basis, a prototype system for real-time video transmission was designed and implemented to verify the feasibility of the encryption algorithm.
