  • Quantum Enigma Machine: Experimentally demonstrating quantum data locking.
    Physical review. A, 2016
    Co-Authors: Daniel J. Lum, John C. Howell, Michael S. Allman, Thomas Gerrits, Varun B. Verma, Sae Woo Nam, Cosmo Lupo, Seth Lloyd
    Abstract:

    Shannon proved in 1949 that information-theoretic-secure encryption is possible if the encryption key is used only once, is random, and is at least as long as the message itself. Notwithstanding, when information is encoded in a quantum system, the phenomenon of quantum data locking allows one to encrypt a message with a shorter key and still provide information-theoretic security. We present one of the first feasible experimental demonstrations of quantum data locking for direct communication and propose a scheme for a quantum Enigma Machine that encrypts 6 bits per photon (containing messages, new encryption keys, and forward error correction bits) with less than 6 bits per photon of encryption key while remaining information-theoretically secure.

  • Quantum Enigma Machines
    arXiv: Quantum Physics, 2013
    Co-Authors: Seth Lloyd
    Abstract:

    Enigma Machines are devices that perform cryptography using pseudo-random numbers. The original Enigma Machine code was broken by detecting hidden patterns in these pseudo-random numbers. This paper proposes a model for a quantum optical Enigma Machine and shows that the phenomenon of quantum data locking makes such quantum Enigma Machines provably secure even in the presence of noise and loss.

  • Securing significant patterns
    International Journal of Information Management, 2015
    Co-Authors: Paul Beynon-davies
    Abstract:

    Provides a fresh examination of a key case of interest to the information disciplines.The paper explores the Enigmatic nature of forma - the physical aspect of a seme or sign.In unpacking the nature of formative action the case material helps re-establish the system in information system.The case enables us to position both IT systems (data systems) and information systems within the wider patterning of significance. The historical case described in this paper, which is based upon a re-interpretation and re-presentation of a vast amount of extant scholarship, centers around the use of the Enigma Machine by German armed forces during the Second World War to secure significant patterns and the related work of the Government Code and Cypher School to decode such communicative patterns. Through a fresh examination of this case and the 'information technologies' used within intelligence work of the day we achieve a number of things. First, we explore the Enigmatic nature of what we term forma - the physical aspect of a seme or sign. We use the case to help illustrate the inherent relationship between the use of forma for mundane purposes of communication and the use of forma to remain mysterious; to mask communicative and performative action. Second, in unpacking the nature of formative action the case material helps re-establish the system in information system. It helps re-conceptualize and broaden the nature of information technology and illustrate more clearly the differences but also the connections between information systems and systems of such technology. Finally, the case enables us to position both IT systems (data systems) and information systems within the wider patterning of significance. This allows us to resurrect the importance of communication and control for the proper conceptualization of situated information systems and their supporting technologies.
