NISTIR 7878 Combinatorial Coverage Measurement

NISTIR 7878 Combinatorial Coverage Measurement D . Richard

Combinatorial testing applies factor covering arrays [6, 7] to test all t-way combinations of input or configuration state space. In some testing situations, it is not practical to use covering arrays, but any set of tests with n parameters covers at least some proportion of t-way combinations up to t ≤ n. This report describes measures of combinatorial coverage that can be used in evaluating t...

Combinatorial Coverage Analysis of Subsets of the TLS Cipher Suite Registry

We present a combinatorial coverage measurement analysis for (subsets) of the TLS cipher suite registries by analyzing the specified ciphers of IANA, ENISA, BSI, Mozilla and NSA Suite B. The method introduced here may contribute towards the design of quality measures of cipher suites, and may also be applied more broadly to the analysis of configurable systems. Keywords—Combinatorial testing, c...

NISTIR 7564, Directions in Security Metrics Research

More than 100 years ago, Lord Kelvin insightfully observed that measurement is vital to deep knowledge and understanding in physical science. During the last few decades, researchers have made various attempts to develop measures and systems of measurement for computer security with varying degrees of success. This paper provides an overview of the security metrics area and looks at possible av...

NISTIR 7224, 4th Annual PKI R&D Workshop "Multiple Paths to Trust" Proceedings

This paper analyses the simplicity of the trust model adopted by the Shibboleth infrastructure and describes an enhanced distributed trust model and authorisation decision making capability that can be implemented by using X.509 attribute certificates and a Privilege Management Infrastructure such as PERMIS. Several different combinatorial approaches can be taken, depending upon the trust model...
