Abstract

The invention discloses a data processing method and device. The method includes: determining a hash value according to the session key negotiated between the data receiving end and the data sending end and the time stamp of the data unit of the data to be transmitted; according to the hash value, repeating the data unit of the data to be transmitted Arrange; send the rearranged data to be transmitted. The invention solves the technical problem in the related art that the working process of all parties in data transmission is fixed, and it is difficult to effectively resist analysis attack means, resulting in poor security.

Description

technical field [0001] The present invention relates to the field of image processing, and in particular, to a data processing method and device. Background technique [0002] Although the existing VGTP protocol is a private 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. SUMMARY OF THE INVENTION [0004] Embodiments of the present invention provide a data processing method and device, so as to at least solve the technical problem in the related art that the working process of all parties in data transmission is fixed, and it is difficult to effectively resist analysis-type attack methods, resulting in poor security. [0005] According to an aspect of the embodiments of the present invention, a data processing method is provided, comprising: determin...
