Recommendation for Block Cipher Modes of Operation: Three Variants of Ciphertext Stealing for CBC Mode
A limitation to Cipher Block Chaining (CBC) mode, as specified in NIST Special Publication 800-38A, is that the plaintext input must consist of a sequence of blocks. Ciphertext stealing is a padding method in which the required padding bits are "stolen"

Security Assurance Levels: A Vector Approach to Describing Security Requirements
Safety systems have used the concept of safety integrity levels (SILs) for almost two decades. This allows the safety of a component or system to be represented by a single number that defines a protection factor required to ensure the health and safety of
Performance Assessments of Two-Way, Free-Form, Speech-to-Speech Translation Systems for Tactical Use
A critical challenge for military personnel when operating in foreign countries is effective communication with the local population. To address this issue, the Defense Advanced Research Projects Agency (DARPA) created the Spoken Language Communication and
Data Sets for the Qualification of Volumetric CT as a Quantitative Imaging Biomarker in Lung Cancer
The drug development industry is faced with increasing costs and decreasing success rates. New ways to understand biology as well as the increasing interest in personalized treatments for smaller patient segments requires new capabilities for the rapid
A New Analysis of the False-Positive Rate of a Bloom Filter
A Bloom filter is a space-efficient data structure used for probabilistic set membership testing. When testing an object for set membership, a Bloom filter may give a false positive. The analysis of the false positive rate is key to understanding the Bloom

In Trust we Trust
The term trust has had a well understood definition for centuries. However after e-trust came along, and then cloud, where e-trust is not sufficient due to the non-touchability of a public cloud, the need to reconsider what trust means for a public cloud
Reliability of Embedded and Cyber-Physical Systems
Cyber-physical systems feature a tight combination of a system's computational and physical elements. Understanding how to assess and design trustworthiness into these complex systems of systems remains an unsolved problem. This issue offers insights into

Further Studies of Bootstrap Variability for ROC Analysis on Large Datasets
The nonparametric two-sample bootstrap is successfully applied to computing the measurement uncertainties in receiver operating characteristic (ROC) analysis on large datasets in areas such as biometrics, speaker recognition system, etc. To determine the
An Inconvenient Truth About Tunneled Authentications
In recent years, it has been a common practice to execute client authentications for network access inside a protective tunnel. Man-in-the-middle (MitM) attacks on such tunneled authentications have been discovered early on and cryptographic bindings are
An Inconvenient Truth About Tunneled Authentications
Practical Combinatorial Testing
Combinatorial testing can help detect problems like this early in the testing life cycle. The key insight underlying t-way combinatorial testing is that not every parameter contributes to every fault and most faults are caused by interactions between a

Modeling Smart Grid Applications with Co-Simulation
Analysis of complex Smart Grid applications require simulation of communications networks and the power system. Analytical models of the communication systems provide a tool for examining the aggregate behavior of the system. An event level analysis in the
A Methodology to Evaluate Wireless Technologies for the Smart Grid
This paper presents a methodology for assessing the suitability of various wireless technologies for meeting the communication requirements of Smart Grid applications. It describes an approach for translating application requirements to link traffic
Simulation of a Medium Frequency Mesh Network for Communications in Underground Mines
Signals at the lower end of the medium frequency range (300 kHz to 3000 kHz) propagate with relatively low attenuation along existing metallic infrastructure in an underground mine, such as cables, pipes and rails. Exploiting this capability, low-bandwidth
Security Architecture Design Process for Health Information Exchanges (HIEs)
The purpose of this publication is to provide a systematic approach to designing a technical security architecture for the exchange of health information that leverages common government and commercial practices and that demonstrates how these practices
Guide to Securing WiMAX Wireless Communications
The purpose of this document is to provide information to organizations regarding the security capabilities of wireless communications using WiMAX networks and to provide recommendations on using these capabilities. WiMAX technology is a wireless
Ethics and the Cloud
Cloud computing is an idea that's rapidly evolving. Still, the amount of money and attention devoted to this topic makes it seems sensible to discuss how ethicists view the kinds of changes in computing that are being called "the cloud." This department is

Using clock accuracy to guide model synthesis in distributed systems: An application in power grid control
Practical implementations in distributed model based control face a fundamental trade-off between model complexity and the number of modeled nodes. For linear systems, higher order models better capture the behavior of the system at higher frequencies
Security Content Automation Protocol (SCAP): Helping Organizations Maintain and Verify the Security of their Information Systems
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-117, Guide To Adopting and Using the Security Content Automation Protocol (SCAP), Version 1.0: Recommendations of the National Institute of Standards and Technology
A DS-CDMA Interference Cancellation Technique for Body Area Networks
A low complexity Parallel Interference Cancellation (PIC) technique that is applicable to body area networks is presented. Using Direct-Sequence Code Division Multiple Access (DS-CDMA), the technique aims at suppressing interference caused by rapid changes
Development of Performance Metrics and Test Methods for First Responder Location and Tracking Systems
The need for the development of performance requirements, metrics and test methods for evaluation of location and tracking systems is increasing as these systems begin to become commercially available for use by emergency responders. A working group was
