Full PMD vector measured directly from modulated data using linear optical sampling
We demonstrate a new technique to monitor the polarization-mode dispersion in a fiber communication channel by analyzing the modulated data at the fiber output measured with Polarization-Sensitive Linear Optical Sampling (PS-LOS).

Access Specification and Validation Framework for Secure Smart ID Cards Deployment
Deployment of smart cards as identity tokens (Smart ID Cards) requires the support of an enterprise system called Identity Management System (IDMS) for collection, storage, processing and distribution of personal identity credentials. Secure configuration

Quantum Key Distribution (QKD) and Commodity Security Protocols: Introduction and Integration
We present an overview of quantum key distribution (QKD), a secure key exchange method based on the quantum laws of physics rather than computational complexity. We also provide an overview of the two most widely used commodity security protocols, IPsec
Characterizing Padding Rules of MD Hash Functions Preserving Collision Security
This paper characterizes collision preserving padding rules and provides variants of Merkle-Damgaard (MD) which are having less or no overhead costs due to length. We first show that suffix-free property of padding rule is necessary as well as sufficient

Digital Signature Standard (DSS)
[Superseded by FIPS 186-4(July 2013): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=914162 ] The Standard specifies a suite of algorithms that can be used to generate a digital signature. Digital signatures are used to detect unauthorized

Security for Enterprise Telework and Remote Access Solutions
Many people telework (also known as telecommuting), which is the ability for an organization s employees and contractors to perform work from locations other than the organization s facilities. Teleworkers use various client devices, such as desktop and

Static Analysis Tool Exposition (SATE) 2008
The NIST SAMATE project conducted the first Static Analysis Tool Exposition (SATE) in 2008 to advance research in static analysis tools that find security defects in source code. The main goals of SATE were to enable empirical research based on large test
Autonomous Migration with Admission Control for Mobiles Affected by Access Network Failures
The loss of a set of wireless network access resources causes every mobile user that is connected through the failed resources to perform an unanticipated hard handover, resulting in disrupted connections. The users connected to the failed resources can be
Vacuum-Gap Capacitors for Low-Loss Superconducting Resonant Circuits
Low-loss microwave components are used in many superconducting resonant circuits from multiplexed readouts of low-temperature detector arrays to quantum bits. Two-level system (TLS) defects in amorphous dielectric materials cause excess energy loss. In an
Guide to Enterprise Telework and Remote Access Security
[Superseded by NIST SP 800-46 Rev. 2 (July 2016): http://www.nist.gov/manuscript-publication-search.cfm?pub_id=921406 ] Many organizations employees and contractors use enterprise telework technologies to perform work from external locations. Most

Measuring Indoor Mobile Wireless Link Quality
This paper investigates methods for link quality measurement of an indoor, time-varying wireless link. Link quality estimates are used for a number of higher-layer functions, including rate adaptation, routing, and topology control. The objective is to
Backbone Construction for Heterogeneous Wireless Ad Hoc Networks
In this paper, we propose a backbone construction scheme over heterogeneous ad hoc networks, where the network nodes have different characteristics such as communication capacity, processing power and energy resource. Most of the wireless backbone
Flexible Solution-Processed Memristors
We have fabricated physically flexible nonvolatile memory devices using inexpensive, room-temperature, solution processing. The behavior of these devices is consistent with that of a memristor device, the missing fourth circuit element theoretically
Quantum Key Distribution System Operating at Sifted-Key Rate Over 4 Mbit/s 1
A complete fiber-based polarization encoding quantum key distribution (QKD) system based on the BB84 protocol has been developed at National Institute of Standard and Technology (NIST). The system can be operated at a sifted key rate of more than 4 Mbit/s
Is Quantum Cryptography Provably Secure?
Quantum cryptography asserts that shared secrets can be established over public channels in such a way that the total information of an eavesdropper can be made arbitrarily small with probability arbitrarily close to 1. As we will show below, the current
Experimental Study of High Speed Polarization -Coding Quantum Key Distribution with Sifted -Key Rates Over Mbit/s
We have demonstrated a polarization encoded, fiber-based quantum key distribution system operating at 850 nm in the B92 protocol. With a quantum bit transmission rate i.e. optical pulse driving frequency of 625 MHz and a mean photon number of 0.1, we
Comparison of interpretability of 1080p30 and 720p60 motion imagery: trade-offs in resolution and frame rate
We have conducted an evaluation comparing the interpretability potential of two standardized HD formats, 1080p30 and 720p60. Despite the lack of an existing motion image (MI) quality scale akin to the NIIRS scale, we have exploited previous work on MI
High Speed Quantum Key Distribution over Optical Fiber Network System
NIST has developed a number of complete fiber-based high-speed quantum key distribution QKD)systems that includes an 850 nm QKD system for a local area network (LAN), a 1310 nm QKD system for a metropolitan area network (MAN), and a 3-node quantum network
Understanding Insecure IT: Practical Risk Assessment
IT systems have long been at risk from vulnerable software, malicious actions, or inadvertent user errors, in addition to run-of-the-mill natural and human-made disasters. As we discussed in the last issue ( Surviving Insecure IT: Effective Patch
