Experimental Demonstration of a Detection-time-bin-shift Polarization Encoding Quantum Key Distribution System
Detection-time-bin-shift (DTBS) is a scheme that uses time division multiplexing of a single photon detector between two photon bases in a quantum key distribution (QKD) system. This scheme can simplify the structure of a QKD system, reduce its cost and
NIST Handbook 150-17, 2008 Edition, National Voluntary Laboratory Accreditation Program, Cryptographic and Security Testing
NIST Handbook 150-17 presents technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Cryptographic and Security Testing (CST) Program. It is intended for information
Policy Specification and Enforcement for Smart ID Cards Deployment
Deployment of Smart Cards for Identity Verification requires collection of credentials and provisioning of credentials from and to heterogeneous and sometimes legacy systems. To facilitate this process, a centralized identity store called Identity
Can TCP Metastability Explain Cascading Failures and Justify Flow Admission Control in the Internet?
This paper discusses implications of possible metastability of TCP-type fair bandwidth sharing under random flow arrivals/departures for understanding and defending the Internet against cascading failures. Cascading failures can be viewed as a process of
With new algorithms and tools, developers can apply high-strength combinatorial testing to detect elusive failures that occur only when multiple components interact. In pairwise testing, all possible pairs of parameter values are covered by at least one
Low Signal-to-noise Ratio Underwater Acoustic Communications
Communications with low input signal-to-noise ratio (SNR) is often called covert communications as the probability of detection and interception decreases with decreasing SNR . Direct-sequence spread-spectrum signaling works at low SNR because of the
Recognizing that the 32-bit addresses used by the current version of the Internet Protocol (IPv4) would soon be depleted, the Internet Engineering Task Force (IETF) has been developing its successor, Internet Protocol version 6 (IPv6). This has been a more
New Cryptographic Hash Algorithm Family: NIST Holds a Public Competition to Find New Algorithms
This bulletin summarizes the information that was disseminated by the National Institute of Standards and Technology (NIST) in a November 2007 Federal Register Notice. NIST is soliciting candidates for a new and robust cryptographic hash algorithm for use
Since the discovery of collision attacks against several well known cryptographic hash functions in 2004 there has been a rush of new cryptanalytic results that cast doubt on our current hash function standards. The relatively new NIST SHA-2 standards are
Capacity of Random Wireless Networks: Impact of Cooperative Network Coding
The throughput capacity of random wireless networks has been studied extensively in the literature. Nevertheless, most existing studies are based on the assumption that each transmission has one sender and one receiver. In our recent study, we have
Subspace Approximation of Face Recognition Algorithms: An Empirical Study
We present a theory for constructing linear subspace approximations to face recognition algorithms and empirically demonstrate that a surprisingly diverse set of face recognition approaches can be approximated well using a linear model. A linear model
Impact of Signaling Load on the UMTS Call Blocking/Dropping
Radio resources in the third generation (3G) wireless cellular networks (WCNs) such as the universal mobile telecommunications system (UMTS) network is limited in term of soft capacity. The quality of a signaling service transmission depends on various
Vehicular ad hoc network (VANET) is recognized as an important component of Intelligent Transportation Systems. The main benefit of VANET communication is seen in active safety systems, which target to increase safety of passengers by exchanging warning
Operational Measures and Accuracies of ROC Curve on Large Fingerprint Data Sets
At any point on a receiver operating characteristic (ROC) curve in combination with two distributions of genuine scores and impostor scores, there are three related variables: the true accept rate (TAR) of the genuine scores, the false accept rate (FAR) of
Experimental Implementation of 1310 nm Differential Phase Shift QKD System with Up-conversion Detectors
We have experimentally implemented a differential phase shift quantum-key distribution system with up-conversion detectors operating at 2.5 Gbps clock rate. A Michelson interferometer with Faraday mirrors is used to increase the system stability.
This paper presents a directional routing approach for multihop ad-hoc networks, which has been applied to two on-demand routing protocols: namely Dynamic Source Routing (DRS) and Ad Hoc On-Demand Distance Vector Routing (AODV). Both DSR-based and AODV
Detection-time-bin-shift Polarization Encoding Quantum Key Distribution System
A detection-time-bin-shift scheme for polarization encoding QKD is proposed. This scheme can reduce cost and overcome the security loss caused by dead-time and the unbalanced characteristics of detectors. This scheme is experimentally demonstrated with the
The rise of blogging as a new grassroots publishing medium and the many interesting peculiarities that characterize blogs compared to other genres of documents opened up several new interesting research areas in the information retrieval field. The Blog
Tight Bounds for the Multiplicative Complexity of Symmetric Functions
The multiplicative complexity of a Boolean function f is defined as the minimum number of binary conjunction (AND) gates required to construct a circuit representing f , when only exclusive-or, conjunction and negation gates may be used. This article
