DATA SCRAMBLING SYSTEM FOR A SHARED TRANSMISSION MEDIA

摘要

Methods of providing added security for communications between a server (36) and a particular client modem (70) on a shared communication media (50). The methods provide for passing communications containing scrambled keys to be used to form scrambling seeds for scrambling subsequent messages. In a preferred embodiment, both the server (36) and the client modem (70) generate and pass keys to be used for the communications between the server (36) and that client modem (70) to achieve a dynamic dual key scrambling system.
