A: All or nearly all failures involve only 1 to 6 factors The key insight underlying combinatorial testing’s effectiveness resulted from a series of studies by NIST from 1999 to 2004. NIST research showed that most software bugs and failures are caused by one or two parameters, with progressively fewer by three or more. That is, they were only revealed when multiple conditions were true. For example, a 2-way interaction fault could be "altitude = 0 AND volume < 2.2". So testing all 2-way combinations of parameter values could detect this problem. A method called "pairwise testing" has been...

SEQUENCE COVERING The sequence covering array construct described below was introduced in: D.R. Kuhn, J.M. Higdon, J.F. Lawrence, R.N. Kacker and Y. Lei, "Combinatorial Methods for Event Sequence Testing", First International Workshop on Combinatorial Testing, in Proceedings of the IEEE Fifth International Conference on Software, Testing, Verification and Validation (ICST 2012), Montreal, Quebec, Canada, April 17-21, 2012, pp. 601-609. Preprint The notion of sequence covering has been extended to ordered combination coverage, with a theorem on necessary and sufficient conditions for...

This research grew out of our 2001 paper on failures in medical device software, which found that the failures were triggered by only 1 to 4 variables interacting. Surprisingly, although "pairwise" testing had been popular for many years, no one had looked at the actual distribution of failures by number of interacting factors. We continued this work and published other papers finding that all, or nearly all, software failures involve interactions among a small number of variables, no more than 6, in thousands of failure reports. Below are some of our research areas. If you'd like to find out...

Base EaaS Architecture Without A Decentralized Root Of Trust In this example, the client system is equipped with a Hardware Root of Trust (HRT) device. Examples of HRT devices are the Trusted Platform Module, Intel® Identity Protection Technology, and the ARM® TrustZone technology. The client system runs a dedicated software application capable of interfacing with the local HRT device on the one end and with the EaaS on the other end. The application communicates with the entropy server using standard plaintext protocols, such as HTTP. The dedicated application initiates the procedure for...

In order to perform FIPS 140 conformance testing, a laboratory must become an accredited CST laboratory under the National Voluntary Laboratory Accreditation Program (NVLAP). A list of current labs may be found by visiting National Voluntary Laboratory Accreditation Program (NVLAP) / Directory Search and under the "Program" drop-down select “ITST: Cryptographic and Security Testing”. Module testing results produced by an accredited CST laboratory can then be submitted to the CMVP in order to seek FIPS 140 module validation. CST labs and NIST each charge fees for their respective parts of the...
