NIST conducted the 2017 Pilot Open Speech Analytic Technologies Evaluation (OpenSAT) Evaluation as the first in a new type of evaluation series. This new series is being designed to combine data domains and speech-analytic tasks including the public-safety-communications domain. This report summarizes the set up and results of the Pilot. The report includes 1) anonymous, composite plots, 2) an analysis of systems output, and 3) the dataset challenges in the evaluation. The methods used in the Pilot OpenSAT Evaluation included speech-activity detection; keyword search; automatic, speech recognition; and, three data domains. Those domains were low-resource language, public-safety communications, and YouTube videos. For the speech-analytics task, participants in the evaluation could choose one or all of the methods and one or all of the data domains.
This document updates and replaces NISTIR 8161.This revised recommendation continues to focus on storing metadata to support video analytics. It reflects NIST’s collaboration with relevant standards community members to facilitate an effective approach workable to all involved.
This Recommendation specifies key-establishment schemes using integer factorization cryptography (in particular, RSA). Both key-agreement and key transport schemes are specified for pairs of entities, and methods for key confirmation are included to provide assurance that both parties share the same keying material. In addition, the security properties associated with each scheme are provided.
This document overviews the possibility of implementing cryptographic primitives using threshold schemes, where multiple components contribute to the operation in a way that attains the desired security goals even if f out of n of its components are compromised. There is also an identified potential in providing resistance against side-channel attacks, which exploit inadvertent leakage from real implementations. Security goals of interest include the secrecy of cryptographic keys, as well as enhanced integrity and availability, among others.
The National Institute of Standards and Technology (NIST) provides cryptographic key management guidance for defining and implementing appropriate key management procedures, using algorithms that adequately protect sensitive information, and planning ahead for possible changes in the use of cryptography because of algorithm breaks or the availability of more powerful computing techniques. NIST Special Publication (SP) 800-57, Part 1, Recommendation for Key Management: General, includes a general approach for transitioning from one algorithm or key length to another. This Recommendation (SP 800-131A) provides more specific guidance for transitions to the use of stronger cryptographic keys and more robust algorithms.
The public safety community has a unique opportunity to improve communication technology for incident response with the creation of the national public safety broadband network (NPSBN). Understanding the problems currently being experienced by first responders with communication technology as well as first responders’ communication technology requests provides the basis for addressing and developing solutions to improve public safety communication. The National Institute of Standards and Technology Public Safety Communications Research usability team has conducted in-depth interviews with approximately 200 first responders representing 13 states in eight Federal Emergency Management Agency (FEMA) regions. The population sample includes urban, suburban, and rural locations, and various levels in the chain of command within the fire, law enforcement, emergency medical services, and communications center disciplines.
