Abstract

The invention discloses an HEVC video encryption method by adopting dynamic integer chaos, which comprises the following steps: firstly, carrying out multiple times of transformation by adopting a keyof a dynamic integer chaos model through a Feistel password structure, and initializing the dynamic integer chaos model to obtain an iterative sequence initial value of the dynamic integer chaos model; adopting a multi-core parallel computing mode to run the chaotic model, and generating an integer chaotic pseudo-random sequence in parallel; secondly, performing transformation for multiple timesby adopting Standard mapping, and selecting 9 integer chaotic pseudo-random sequences required by HEVC video encryption; and carrying out XOR encryption on nine syntax elements in the HEVC entropy coding binarization process by utilizing the nine selected integer chaotic pseudo-random sequences to realize HEVC video encryption. According to the method, the high efficiency of video encryption can be improved on the basis of ensuring the security of video encryption, and the method is suitable for the fields of video conferences with strict requirements on real-time performance and the like.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an HEVC video encryption method using dynamic integer chaos. Background technique [0002] The rapid development of Internet technology has brought various industries into the information age, and the role and importance of information in social life has become increasingly prominent. Compared with other multimedia information, video contains extremely rich information and is widely accepted by the public. 80% of the vast Internet users in my country are online audio and video users. With the development of computer technology and smart phones, people not only have high requirements for video quality, but also pay more and more attention to video security. Regardless of whether it is in a highly confidential field such as military or politics, or in a commercial field, illegal copying, dissemination, and destruction of videos will cause property losses and endanger ...
