4K-DRM Server Protocol Packet Capture and Analysis

In order to cooperate with the formulation of the "People's Republic of China Radio and Television Industry Standards-- Technical specification of digital rights management for video audio content distribution", a fusion media copyright protection product and system test evaluation platform supporting domestic passwords was constructed, and the end-to-end multimedia copyright protection system was implemented. Test evaluation requires compatibility testing of the DRM (Digital Rights Management) system. This paper captures and filters the HTTP protocol packets in the 4K-DRM system, and then analyzes the compliance of the HTTP packet protocol such as key synchronization, key query, and content authorization to determine whether the system passes the compatibility test.
