  • Patent number: 7430292
    Abstract: A system is provided for generating information for secure transmission from a first device to a second device. The system comprising a key scheduler for generating a dynamic secret key, a synchronization generator for generating a synchronization sequence and controlling the frequency of the dynamic secret key, a padding generator for generating a padding sequence, and a DEK generator for generating encrypted text. The system generating a stream of encrypted information that includes the synchronization sequence prior to and adjacent the encrypted text which is prior to and adjacent the padding sequence.

  • Publication number: 20080063028
    Abstract: Methods for wireless communication may include selection of a photonic signal to generate a carrier frequency for wireless communication. In an illustrative example, the selected photonic signal may have sidebands with a frequency difference corresponding to a carrier frequency within one of multiple predetermined carrier frequency bands. In some implementations, each of the predetermined carrier frequency bands may contain a local minimum signal attenuation characteristic over a signal path of the wireless communication. For example, the selection of the photonic signal may be based on predetermined selection criteria such as error information, and/or signal path conditions (e.g., atmospheric humidity level, noise, signal strength). Apparatus for performing such methods may include a wireless communication system with a transmitter and/or receiver.
