Abstract

The invention discloses a data processing method and device. The method comprises the following steps: determining a hash value according to a session key negotiated by a data receiving end and a datasending end and a timestamp of a data unit of to-be-transmitted data; rearranging the data units of the to-be-transmitted data according to the hash value; sending the rearranged data to be transmitted. According to the method disclosed in the invention, the technical problem of poor security caused by the fact that the working process of each data transmission party is fixed and analysis attackmeans are difficult to effectively defend in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a data processing method and device. Background technique [0002] Although the existing VGTP protocol is a proprietary protocol, the entire working process is fixed. Although the output code stream results are related to image changes, there are still security risks and cannot effectively resist analysis attacks. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a data processing method and device to at least solve the technical problems in the related art that the working processes of all parties involved in data transmission are fixed, and it is difficult to effectively resist analysis attacks, resulting in poor security. [0005] According to an aspect of an embodiment of the present invention, a data processing method is provided, including: determining the h...
