ABSTRACT:
A cryptographic communication system and method having a first plurality of stations, each of the first plurality of stations having at least one encryption key Kj, were j is a number greater than 2, a data packet D to be viewed by each of the first plurality of stations, means for encrypting the data packet by each of the first plurality of stations to form an encrypted data packet Ejfor transmission to a central processor, and means for combining each of the encrypted data packets, wherein the means for encrypting is applied in parallel to allow each of the first plurality of stations to view the contents of the data packet D prior to encrypting the data packet D.
