Abstract

The invention discloses a streaming media real-time encryption method and system based on video transmission. The method includes the following steps: (1) dividing the encoded video into blocks, (2) converting each video block into ciphertext blocks through encryption , the encryption process includes using the initial value and control parameters of the Chebyshev mapping as the secondary key, using Chebyshev as the primary key to generate the mapping, performing iterations to generate a chaotic sequence key, using the initial value and constant of the Tent mapping as the secondary key, using Tent Generate a map for the secondary key, iteratively generate a chaotic sequence key; perform a bitwise XOR operation on the above chaotic sequence key to generate an intermediate key; then generate the final key through the bitwise XOR of the above intermediate key; The key is brought into the AES algorithm for encryption to form a ciphertext block; (3) all the ciphertext blocks generated in step (2) are combined to form the final ciphertext. The invention improves the security of real-time video encryption and improves the encryption effect of streaming media data.

Description

technical field [0001] The present invention relates to the technical field of streaming media encryption, in particular, to an encryption method and system for streaming media information based on video transmission. Background technique [0002] Streaming media is also called streaming media. It means that the merchant uses a video transmission server to send the program as a data packet and transmit it to the network. After the user decompresses the data through the decompression device, the program will be displayed as before transmission. Judging from the information contained in multimedia files or real-time multimedia data streams, most of the data is video information. [0003] With the widespread popularization of digital video in recent years, the network application of digital video has entered a new stage. Thousands of digital videos are spreading on the Internet every day, so how to protect the security of these digital videos is particularly important. At pre...
