Abstract

The invention discloses a video transmission method and system, and the method comprises the steps: enabling a video monitoring safety terminal to communicate with a key server through a device key, so as to obtain an initial working key; the video monitoring security terminal determines a first video encryption key based on the initial working key, and performs encryption processing on monitored video source data by using the first video encryption key to obtain video encryption data; a video server communicates with the key server to obtain the initial working key; and the video server determines a second video encryption key based on the initial working key, and decrypts the video encryption data based on the second video encryption key to obtain the video source data. According to the method provided by the invention, the key updating negotiation process is simplified, the security mechanism that the equipment key and the working key are different is adopted, the security of the equipment key is ensured, the complexity, the equipment investment and the resource demand of the whole system can be reduced, and the video transmission efficiency is ensured.

Description

technical field [0001] The present invention relates to the technical field of video transmission, and more specifically, to a video transmission method and system. Background technique [0002] With the wide application of various video, the security problem of video information is also becoming more and more prominent. Video applications are mainly divided into two aspects: storage-oriented and transmission-oriented. For storage-oriented applications, for example, some important video databases need to encrypt the video content stored on storage media such as hard disks, and legitimate users can only decrypt and watch the correct video after obtaining the correct key. There are many transmission-oriented video applications, such as video conferencing, video telephony, streaming media, and telemedicine. In important fields such as military defense, party and government agencies, and e-commerce, the above-mentioned various types of video transmissions have an urgent need f...
