  • QUANTUM ENCRYPTED DATA TRANSMISSION IN OPTICALLY-AMPLIFIED WDM COMMUNICATIONS
    Publication number: 20130089204
    Abstract: A quantum cryptographic protocol is proposed, which uses two-mode coherent states and an M-ary modulation format determined in part by an expanded secret key. The encrypted signal is optically amplifiable, resulting in a polarization independent system that is compatible with the existing WDM communications infrastructure.
    Type: Application

  • Streaming implementation of AlphaEta physical layer encryption
    Patent number: 7697687
    Abstract: A method of synchronizing the encryption/decryption functions of an AlphaEta physical-layer encryption or key generation system. The method includes the insertion of a header to indicate the start of encryption after clock-synchronization has been established. The method also allows for a side-channel to signal other useful information, such as a loss-of-syncrhonization signal from Bob or to synchronize a dynamic key change.

  • Coherent-states based quantum data-encryption through optically-amplified WDM communication networks
    Publication number: 20050141716
    Abstract: A quantum cryptographic protocol uses two-mode coherent states that is optically amplifiable, resulting in a polarization independent system that is compatible with the existing WDM infrastructure and which provides secure data encryption suitable for wavelength division multiplexing networks through an in-line amplified line.
