Abstract
The present disclosure relates to systems and methods for assembling and extracting command and control data. In embodiments of the present disclosure, the command and control data is segmented and inserted into multiple packet headers. The header packets are identified by flags such as “First portion,” “Middle portion,” “Last portion,” or “Null Byte.” When a receiver extracts the command and control data from the headers, it tracks the flags associated with the headers. The command and control data is saved to buffer in association with its associated flag. The receiver uses the flags to determine when all command and control data headers have been received. The command and control data is then reconstructed and used to decrypt audio visual content.
