  • Framework for Wireless Network Security Using Quantum Cryptography-Journal
    FRAMEWORK FOR WIRELESS NETWORK SECURITY USING QUANTUM CRYPTOGRAPHY Priyanka Bhatia1 and Ronak Sumbaly2 1, 2 Department of Computer Science, BITS Pilani Dubai, United Arab Emirates ABSTRACT Data that is transient over an unsecured wireless network is always susceptible to being intercepted by anyone within the range of the wireless signal. Hence providing secure communication to keep the user’s information and devices safe when connected wirelessly has become one of the major concerns. Quantum cryptography provides a solution towards absolute communication security over the network by encoding information as polarized photons, which can be sent through the air. This paper explores on the aspect of application of quantum cryptography in wireless networks. In this paper we present a methodology for integrating quantum cryptography and security of IEEE 802.11 wireless networks in terms of distribution of the encryption keys. KEYWORDS IEEE 802.11, Key Distribution, Network Security, Quantum Cryptography, Wireless Network. 1. INTRODUCTION Wireless Networks are becoming increasing widespread, and majority of coffee shops, airports, hotels, offices, universities and other public places are making use of these for a means of communication today. They’re convenient due to their portability and high-speed information exchange in homes, offices and enterprises. The advancement in modern wireless technology has led users to switch to a wireless network as compared to a LAN based network connected using Ethernet cables. Unfortunately, they often aren’t secure and security issues have become a great concern. If someone is connected to a Wi-Fi network, and sends information through websites or mobile apps, it is easy for someone else to access this information.

Numerous countries and research institutes have invested enormous resources to execute correlation studies on QKD networks. Thus, in this study, we surveyed existing QKD network studies and practical field experiments to summarize the research results (e.g., type and architecture of QKD networks, key generating rate, maximum communication distance, and routing protocol). Furthermore, we highlight the three challenges and future research issues in the security of QKD networks and then provide some feasible resolution strategies for these challenges.

  • PMG Phd Thesis FINAL
    Practical Free-Space Quantum Key Distribution Philip Michael Gorman B.Sc. (Hons), MInstP. Thesis submitted for the degree of Doctor of Philosophy Department of Physics Heriot-Watt University December 2010 The copyright in this thesis is owned by the author. Any quotation from the thesis or use of any of the information contained in it must acknowledge this thesis as the source of the quotation or information. ABSTRACT Within the last two decades, the world has seen an exponential increase in the quantity of data traffic exchanged electronically. Currently, the widespread use of classical encryption technology provides tolerable levels of security for data in day to day life. However, with one somewhat impractical exception these technologies are based on mathematical complexity and have never been proven to be secure. Significant advances in mathematics or new computer architectures could render these technologies obsolete in a very short timescale. By contrast, Quantum Key Distribution (or Quantum Cryptography as it is sometimes called) offers a theoretically secure method of cryptographic key generation and exchange which is guaranteed by physical laws. Moreover, the technique is capable of eavesdropper detection during the key exchange process. Much research and development work has been undertaken but most of this work has concentrated on the use of optical fibres as the transmission medium for the quantum channel. This thesis discusses the requirements, theoretical basis and practical development of a compact, free-space transmission quantum key distribution system from inception to system tests. Experiments conducted over several distances are outlined which verify the feasibility of quantum key distribution operating continuously over ranges from metres to intercity distances and finally to global reach via the use of satellites.

  • Current Status of the DARPA Quantum Network
    Current status of the DARPA Quantum Network Chip Elliott1, Alexander Colvin, David Pearson, Oleksiy Pikalo, John Schlafer, Henry Yeh BBN Technologies, 10 Moulton Street, Cambridge MA 02138 ABSTRACT This paper reports the current status of the DARPA Quantum Network, which became fully operational in BBN’s laboratory in October 2003, and has been continuously running in 6 nodes operating through telecommunications fiber between Harvard University, Boston University, and BBN since June 2004. The DARPA Quantum Network is the world’s first quantum cryptography network, and perhaps also the first QKD systems providing continuous operation across a metropolitan area. Four more nodes are now being added to bring the total to 10 QKD nodes. This network supports a variety of QKD technologies, including phase-modulated lasers through fiber, entanglement through fiber, and freespace QKD. We provide a basic introduction and rational for this network, discuss the February 2005 status of the various QKD hardware suites and software systems in the network, and describe our operational experience with the DARPA Quantum Network to date. We conclude with a discussion of our ongoing work. Keywords: quantum cryptography, quantum key distribution, QKD, BB84, entanglement, Cascade 1. INTRODUCTION It now seems likely that Quantum Key Distribution (QKD) techniques can provide practical building blocks for highly secure networks, and in fact may offer valuable cryptographic services, such as unbounded secrecy lifetimes, that can be difficult to achieve by other techniques. Unfortunately, however, QKD’s impressive claims for information assurance have been to date at least partly offset by a variety of limitations. For example, traditional QKD is distance limited, can only be used across a single physical channel (e.g.
