Extraction System

All inbound RTP packets are sent to the extraction system where potential message data is extracted, decrypted, and then verified. The extraction system is essentially a reverse of the embedding system described in Section and then a pass through the symmetric encryption system described in Section . This results in an decrypted potential message where the message's Checksum / ID header field value can be verified to determine whether or not the extracted potential message is valid.

If an extracted potential message is found to be valid, it is passed to the message handler component.
