Abstract :
We put forward a new method for using dynamic keys to encrypt video information on the theory and characteristics of the H.264 video compression standard. The dynamic key encrypts the most important parts of video information, not only to ensure the safety of the information but also to improve the transmission rate. The algorithm is implemented in JM12.4, experimental results show that the new algorithm of encryption achieves a greatly improved effect.
