摘要： An improved method and apparatus encrypts and scrambles information cells transmitted on a telephone system local loop (11') from a central office to a plurality of user premises networks (14') via a shared medium passive optical network. Prior to transmission, the information cell is encrypted for security purposes and scrambled to improve its transmission properties by modulo 2 addition (218) of the information cell and a combined (214) encryption (211) and scrambling sum (212) pattern. At the other end of the passive optical network which is connected to user premises networks, the received encrypted and scrambled information cells are used to generate a processed cell by the modulo 2 addition of the received cell and a combined decryption and descramble sum pattern.

摘要： The present invention provides a telecommunication network utilizing a passive optical network connecting a plurality of network terminations to a local exchange. Information cells and commands are transmitted on the network by the local exchange to all the network terminations. The information cells and commands contain routing address information for the particular network termination to which the information cell or command is destined. The address information contains the address of the destination network termination and additional identifier bits to facilitate encryption of the address information for security and privacy of traffic behavior without producing misdelivery occurrences. In addition, a system for repeatedly changing encryption patterns for the network terminations which detects misdelivery conditions is provided.
