Tracing secure information flow through mode changes

Fidge, Colin J. & McComb, Tim (2006) Tracing secure information flow through mode changes. In Estivill-Castro, V. & Dobbie, G. (Eds.) 29th Australasian Computer Science Conference (ACSC 2006), 16-19 January 2006, Hobart.


Communications devices intended for use in security-critical applications must be rigorously evaluated to ensure they preserve data confidentiality. This process includes tracing the flow of classified information through the device's circuitry. Previous work has shown how this can be done using graph analysis techniques for each of the device's distinct operating modes. However, such analyses overlook potential information flow between modes, via components that store information in one mode and release it in another. Here we show how graph-based analyses can be extended to allow for information flow through sequences of consecutive modes.

Search Google Scholar™

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
