Secure Hash Standard

August 4, 2015
Author(s)
National Institute of Standards and Technology (NIST), Quynh Dang
This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. The Applicability Clause of this standard was revised to

SHA-3 Standard: Permutation-Based Hash and Extendable-Output Functions

August 4, 2015
Author(s)
National Institute of Standards and Technology (NIST), Morris J. Dworkin
This Standard specifies the Secure Hash Algorithm-3 (SHA-3) family of functions on binary data. Each of the SHA-3 functions is based on an instance of the KECCAK algorithm that NIST selected as the winner of the SHA-3 Cryptographic Hash Algorithm

Extending the Cybersecurity Digital Thread with XForms

August 3, 2015
Author(s)
Joshua Lubell
The digital thread for cybersecurity enables security technologies and data sources to interoperate. It consists of an integrated collection of languages, taxonomies, and metrics represented using the Extensible Markup Language (XML). A gap in the

Analysis of Network Segmentation Techniques in Cloud Data Centers

July 30, 2015
Author(s)
Ramaswamy Chandramouli
Cloud Data centers are predominantly made up of Virtualized hosts. The networking infrastructure in a cloud (virtualized) data center, therefore, consists of the combination of physical IP network (data center fabric) and the virtual network residing in

Password policy languages: usable translation from the informal to the formal

July 21, 2015
Author(s)
Michelle P. Steves, Mary F. Theofanos, Celia Paulsen, Athos Ribeiro
Password policies – documents which regulate how users must create, manage, and change their passwords – can have complex and unforeseen consequences on organizational security. Since these policies regulate user behavior, users must be clear as to what is

PFLASH - Secure Asymmetric Signatures on Smart Cards

July 21, 2015
Author(s)
Ming-Shing Chen, Bo-Yin Yang, Daniel Smith-Tone
We present PFLASH, an asymmetric digital signature scheme appropriate for smart card use. We present parameters for several security levels in this low resource environment and bootstrap many technical properties (including side-channel resistance) exposed

Privacy and Security in the Brave New World: The Use of Multiple Mental Models

July 21, 2015
Author(s)
Susanne M. Furman, Mary F. Theofanos, Brian C. Stanton, Sandra S. Prettyman
We live in a world where the flow of electronic information and communication has become a ubiquitous part of our everyday life. While our lives are enhanced in many ways, we also experience a myriad of challenges especially to our priva-cy and security

Defensive Resource Allocations with Security Chokepoints in IPv6 Networks

July 15, 2015
Author(s)
Assane Gueye, Peter M. Mell, Richard Harang, Richard J. La
Securely configured Internet Protocol version 6 networks can be made resistant to network scanning, forcing attackers to propagate following existing benign communication paths. We exploit this attacker limitation in a defensive approach in which

Measuring Limits on the Ability of Colluding Countries to Partition the Internet

June 30, 2015
Author(s)
Peter M. Mell, Richard Harang, Assane Gueye
We show that the strength of Internet-based network interconnectivity of countries is increasing over time. We then evaluate bounds on the extent to which a group of colluding countries can disrupt this connectivity. We evaluate the degree to which a group
