  • Patent number: 8149879
    Abstract: A method of data transmission according to one embodiment of the invention includes encoding a set of data values to produce a corresponding series of ordered n-tuples. The method also includes transmitting, according to the series of ordered n-tuples, a plurality of bursts over a plurality n of frequency bands. Specifically, for each of the plurality of bursts, a frequency band occupied by the burst is indicated by the order within its n-tuple of an element corresponding to the burst. A bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. Information is encoded into a polarity of at least one of the plurality of bursts.

  • Publication number: 20020116606
    Abstract: An encryption and decryption system and method for message forwarding in a multi-node network which provides fast message forwarding while minimizing CPU time and power requirements by unconditional decryption of all incoming messages and unconditional encryption or re-encryption of all outgoing messages, which pass through a forwarding node or nodes. Messages from a source node to the destination node pass through the forwarding node, which unconditionally decrypts the incoming message from the source node without prior determination of the ultimate destination of the message. The forwarding node then unconditionally re-encrypts the outgoing or forwarded message for transmission to the destination node.
