On various nonlinearity measures for boolean functions

May 19, 2016
Author(s)
Joan Boyar, Magnus G. Find, Rene Peralta
A necessary condition for the security of cryptographic functions is to be "sufficiently distant" from linear, and cryptographers have proposed several measures for this distance. We show that six common measures, nonlinearity, algebraic degree

Combinatorial Testing for Cybersecurity and Reliability

May 12, 2016
Author(s)
David R. Kuhn, Raghu N. Kacker, Larry Feldman, Gregory A. Witte
This bulletin focuses on NIST's combinatorial testing work. Combinatorial testing is a proven method for more effective software testing at lower cost. The key insight underlying combinatorial testing's effectiveness resulted from a series of studies by

Combinatorial Coverage Analysis of Subsets of the TLS Cipher Suite Registry

May 11, 2016
Author(s)
Dimitris Simos, Kristoffer Kleine, D. Richard Kuhn, Raghu N. Kacker
We present a combinatorial coverage measurement for (subsets) of the TLS cipher suite registries by analyzing the specified ciphers of IANA, ENISA, BSI, Mozilla and NSA Suite B. Our findings contribute towards the design of quality measures of recommended

Shape Retrieval of Non-Rigid 3D Human Models

April 26, 2016
Author(s)
Afzal A. Godil, David Pickup
3D models of humans are commonly used within computer graphics and vision, and so the ability to distinguish between body shapes is an important shape retrieval problem. We extend our recent paper which provided a benchmark for testing non-rigid 3D shape

Measuring the Usability and Security of Permuted Passwords on Mobile Platforms

April 25, 2016
Author(s)
Kristen K. Greene, John M. Kelsey, Joshua M. Franklin
Password entry on mobile devices significantly impacts both usability and security, but there is a lack of usable security research in this area, specifically for complex password entry. To address this research gap, we set out to assign strength metrics

Guidelines for the Creation of Interoperable Software Identification (SWID) Tags

April 22, 2016
Author(s)
David A. Waltermire, Brant Cheikes, Larry Feldman, Gregory A. Witte
This report provides an overview of the capabilities and usage of software identification (SWID) tags as part of a comprehensive software lifecycle. As instantiated in the International Organization for Standardization/International Electrotechnical

Public Safety Analytics R&D Roadmap

April 19, 2016
Author(s)
Tracy A. McElvaney, Ryan Felts, Marc Leh
The public safety community is in a period of great transition. Over the next 20 years, technology advancements will increase accessibility of data/video applications to public safety, and allow for the eventual migration of voice communications from

New NIST Security Standard Can Protect Credit Cards, Health Information

April 14, 2016
Author(s)
Morris J. Dworkin, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-38G, "Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption." The publication specifies two methods for format-preserving

JPEG 2000 CODEC Certification Guidance for 1000 ppi Fingerprint Friction Ridge Imagery

April 13, 2016
Author(s)
John M. Libert, Shahram Orandi, Michael D. Garris, Frederick R. Byers, John D. Grantham
The document describes the procedure by which applications of JPEG 2000 CODECs will be evaluated with respect to conformance to the NIST guidance for compression of 1000 ppi friction ridge images as detailed in NIST Special Publication 500-289 [NIST5]

The Need for Realism when Simulating Network Congestion

April 2, 2016
Author(s)
Kevin L. Mills, Christopher E. Dabrowski
Many researchers use simulation to investigate network congestion, often finding congestion spread can be modeled as percolation, spreading slowly under increasing load until a critical point, then spreading quickly through the network. The researchers
