Abstract

The invention provides an encryption method and device for a live and recorded broadcast interaction system. The method comprises the following steps that a transmitting end divides each frame of image in a teaching video stream into blocks; the image blocks of each frame of image are numbered sequentially, the image blocks are stored in an unordered manner, and a number sequence of the image blocks which are stored in the unordered manner is obtained; a first encryption algorithm is used to encrypt the number sequence and further to generate a first cryptograph; and the first cryptograph is combined with data of the image blocks which are stored in the unordered manner, and combined data is sent to a reception end. The new encryption method is used to encrypt the data, the encryption process is simplified on the premise that the security is ensured, a distributed authentication mechanism is employed, and an un-authorized device is prevented from accessing the live and recorded broadcast interaction system.

Description

technical field

[0001] The invention belongs to the field of network communication, and in particular relates to an encryption method and device for a live recording and broadcasting interactive system. Background technique

[0002] Data is easy to be stolen during transmission, so the data will be encrypted to enhance the security of data during transmission. The current encryption method is to directly encrypt the data itself, which increases the complexity of the encryption algorithm. Therefore, A new encryption method is needed to simplify the complexity of the encryption process. Contents of the invention

[0003] The present invention provides an encryption method and device for a live recording and broadcasting interactive system to solve the above problems.

[0004] The present invention provides an encryption method for a live recording and broadcasting interactive system, comprising the following steps: the sending end performs block processing on each frame of ...

Examples

Embodiment Construction

[0013] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0014] figure 1 Shown is a flowchart of an encryption method used in a live recording and broadcasting interactive system provided according to a preferred embodiment of the present invention. like figure 1 As shown, the encryption method for the live recording and broadcasting interactive system provided by the preferred embodiment of the present invention includes steps 102-108.

[0015] Step 102, the sending end performs block processing on each frame of image in the teaching video stream;

[0016] Step 104, sequentially numbering the image blocks of each frame of image, storing the image blocks of each frame of image out of order, and obtaining the numbering sequence of the image blocks stored...
