Using 3D Nanotomography to Visualize Defects in the Fabrication of Superconducting Electronics

Using 3D Nanotomography to Visualize Defects in the Fabrication of Superconducting Electronics

Superconducting electronics is an established technological field for sensors, quantum computation and quantum-based standards and is emerging as an important low-power alternative to semiconductors. As in any electronics fabrication, the production of

Multiplicative Complexity of Vector Value Boolean Functions

Multiplicative Complexity of Vector Value Boolean Functions

We consider the multiplicative complexity of Boolean functions with multiple bits of output, studying how large a multiplicative complexity is necessary and sufficient to provide a desired nonlinearity. For so-called $\Sigma\Pi\Sigma$ circuits, we show

Predictive Models for Min-Entropy Estimation

Predictive Models for Min-Entropy Estimation

Random numbers are essential for cryptography. In most real-world systems, these values come from a cryptographic pseudorandom number generator (PRNG), which in turn is seeded by an entropy source. The security of the entire cryptographic system then

Towards Unified Perron-Frobenius Framework for Managing Systemic Risk in Networked Systems

Towards Unified Perron-Frobenius Framework for Managing Systemic Risk in Networked Systems

Along with economic and convenience benefits, interconnectivity also brings potential risks and drawbacks. System designers and operators are faced with problem of balancing the relevant systemic risk/benefit tradeoffs. Assuming that system components are

Scalable Synchrophasors Communication Network Design and Implementation for Real-time Distributed Generation Grid

Scalable Synchrophasors Communication Network Design and Implementation for Real-time Distributed Generation Grid

There has been a growing interest in the deployment of Phasor Measurement Units (PMUs) not only in high-voltage transmission, but in lower-voltage distribution systems. For a Distributed Generation (DG) grid this would require deployment of PMUs at

Guest Editorial Article: Special Issue on Cyber Physical Systems and Security for Smart Grid

Although there are many important CPS systems in practice, one of the most complex applications is the Smart Grid whose function is to distribute reliable and efficient electric energy with a high degree of sustainability. While the Smart Grid aims to

Retrieval and classification methods for textured 3D models: A comparative study

This paper presents a comparative study of six methods for the retrieval and classification of tex- tured 3D models, which have been selected as represen- tative of the state of the start and evaluated through 17 runs. To better analyse and control how

gtklogger: A Tool For Systematically Testing Graphical User Interfaces

We describe a scheme for systematically testing the operation of a graphical user interface. The scheme provides a capability for generating event logs, which are recordings of a user session with the interface. These logs can be annotated with assertion

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

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

Secure Hash Standard

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

Effects of Password Permutation on Subjective Usability Across Platforms

Effects of Password Permutation on Subjective Usability Across Platforms

The current work examines subjective password usability across platforms—desktop, smartphone, and tablet—using system- generated passwords that adhere to the stricter password requirements found in higher-security enterprise environments. This research

Constructive Relationships Between Algebraic Thickness and Normality

Constructive Relationships Between Algebraic Thickness and Normality

We study the relationship between two measures of Boolean functions; "algebraic thickness" and "normality". For a function f, the algebraic thickness is a variant of the "sparsity", the number of nonzero coefficients in the unique F_2 polynomial

The Authentication Equation: A Tool to Visualize the Convergence of Security and Usability of Text-Based Passwords

Password management is the ubiquitous struggle of the modern human. Despite usability playing a vital role in authentication, many password policies and requirements focus on security without sufficient consideration of human factors. In fact, security and
