This paper documents the design, layout and algorithms of the IUPAC International Chemical Identifier, InChI.

Privacy Amplification in the Isolated Qubits Model

April 14, 2015
Author(s)
Yi-Kai Liu
Isolated qubits are a special class of quantum devices, which can be used to implement tamper-resistant cryptographic hardware such as one-time memories (OTM's). Unfortunately, these OTM constructions leak some information, and standard methods for privacy

Password Entry Errors: Memory or Motor?

April 9, 2015
Author(s)
Kristen Greene, Frank Tamborello
As we increasingly rely upon our computer information systems to store and operate on sensitive information, the methods we use to authenticate user identity also become more important. One of the most important such methods is the password. However

Towards a "Periodic Table" of Bugs

April 8, 2015
Author(s)
Irena Bojanova
Our vision for a "periodic table" of bugs is a "natural" organization of a catalog or dictionary or taxonomy to describe software weaknesses and vulnerabilities. Such an organization will help the community to: a) more closely explain the nature of

ACT-R Modeling of Password Entry Errors

April 2, 2015
Author(s)
Kristen Greene, Franklin Tamborello
Validated predictive models of human error for password-related tasks could better inform password requirements for both government and civilian systems. Here, we build upon prior modeling work focused on disentangling the source of password entry errors

Combinatorial Coverage as an Aspect of Test Quality

March 31, 2015
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
There are relatively few good methods for evaluating test set quality, after ensuring basic requirements traceability. Structural coverage, mutation testing, and related methods can be used if source code is available, but these approaches may entail

Assessing Effects of Asymmetries, Dynamics, and Failures on a Cloud Simulator

March 29, 2015
Author(s)
Kevin L. Mills, James J. Filliben, Christopher E. Dabrowski
We characterize the effects of asymmetries, dynamics, and failures when introduced into a cloud computing simulator, which had previously been characterized under static, homogeneous configurations with various patterns of demand and supply. We aim to

TRECVID 2014 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

March 26, 2015
Author(s)
Paul D. Over, Jonathan G. Fiscus, Gregory A. Sanders, David M. Joy, Martial Michel, George Awad, Alan Smeaton, Wessel Kraaij, Georges Quenot
The TREC Video Retrieval Evaluation (TRECVID) 2014 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last
