Abstract
A private broadcasting system includes communication terminals which are coupled to both a broadcasting network and point-to-point network. A private broadcasting device included in the broadcasting system is coupled to a database that contains a pool of encryption keys and a pool of channel numbers. The encryption keys and channel numbers are assigned to a private broadcast request when the communicating partners of the private broadcast request are available for communication. The encryption key and channel number is issued to each of the participating terminals. Each of the participating terminals encrypts and de-encrypts the information transmitted on and received from the broadcasting channel at the assigned channel number. In this way, the terminals communicate with each other privately excluding all other terminals that are not part of the private broadcast communication.
