Abstract
A master key may be used by each participant in a secure communication. Indeed, each participant may select and encryption key from a distinct end of the master key. To eliminate a necessity for the end points in the secure communication to maintain a master key corresponding to every possible correspondent, the participants may communicate through an encryption server.
