Blockchain Technology Overview

October 3, 2018

Author(s)

Dylan J. Yaga, Peter M. Mell, Nik Roby, Karen Scarfone

Blockchains are tamper evident and tamper resistant digital ledgers implemented in a distributed fashion (i.e., without a central repository) and usually without a central authority (i.e., a bank, company, or government). At their basic level, they enable

Interpolation-Based Gray-Level Co-Occurrence Matrix Computation for Texture Directionality Estimation

September 19, 2018

Author(s)

Antonio Cardone, Marcin Kociolek, Mary C. Brady, Peter Bajcsy

A novel interpolation-based model for the computation of the Gray Level Co-occurrence Matrix (GLCM) is presented. The model enables GLCM computation for any real-valued angles and offsets, as opposed to the traditional, lattice-based model. A texture

2017 NIST/ITL Cybersecurity Program: Annual Report

September 18, 2018

Patrick D. O'Reilly, Kristina G. Rigopoulos, Gregory A. Witte, Larry Feldman

Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry

Dynamic Job Replication for Balancing Fault Tolerance, Latency, and Economic Efficiency: Work in Progress

September 6, 2018

Author(s)

Vladimir V. Marbukh

Recent research has demonstrated benefits of replication of requests with canceling, which initiates multiple concurrent replicas of a request and uses the first successful result immediately removing the remaining replicas of the completed request from

On Mitigation Inefficiency of Selfish Investment in Network Recovery from High Loss SIS Infection

September 6, 2018

Author(s)

Vladimir V. Marbukh

This paper reports on quantification and mitigation of the inefficiency of selfish investment in network recovery from Susceptible Infected Susceptible (SIS) infection in a practically important case of high losses due to infection. In this case, both

Network Formation by Contagion Averse Agents: Modeling Bounded Rationality with Logit Learning

August 31, 2018

Author(s)

Vladimir V. Marbukh

Economic and convenience benefits of interconnectivity drive current explosive emergence and growth of networked systems. However, as recent catastrophic contagious failures in numerous large scale networked infrastructures demonstrated, these benefits of

Securing Wireless Infusion Pumps in Healthcare Delivery Organizations

August 20, 2018

Author(s)

Gavin W. O'Brien, Sallie Edwards, Kevin Littlefield, Neil McNab, Sue Wang, Kangmin Zheng

Medical devices, such as infusion pumps, were once standalone instruments that interacted only with the patient or medical provider. However, todays medical devices connect to a variety of healthcare systems, networks, and other tools within a healthcare

Cybertrust in the IoT Age

User Context: An Explanatory Variable in Phishing Susceptibility

July 15, 2018

Author(s)

Kristen K. Greene, Michelle P. Steves, Mary Theofanos, Jennifer A. Kostick

Extensive research has been performed to examine the effectiveness of phishing defenses, but much of this research was performed in laboratory settings. In contrast, this work presents 4.5 years of workplace-situated, embedded phishing email training

In IoT We Trust?

July 13, 2018

Author(s)

Jeff Voas, D. Richard Kuhn, Phillip Laplante

In this short article, we review an abbreviated list of trust challenges that we foresee as increased adoption transforms the IoT into another ubiquitous technology just as the Internet is. These challenges are in no specific order, and are by no means a
