A Historical Perspective on Runtime Assertion Checking in Software Development
This report presents initial results in the area of software testing and analysis produced as part of the Software Engineering Impact Project. The report describes the historical development of runtime assertion checking, including a description of the origins of and significant features associated with assertion checking mechanisms, and initial findings about current industrial use. A future report will provide a more comprehensive assessment of development practice, for which we invite readers of this report to contribute information
Statically checking confidentiality via dynamic labels
This paper presents a new approach for verifying confidentiality
for programs, based on abstract interpretation. The
framework is formally developed and proved correct in the
theorem prover PVS. We use dynamic labeling functions
to abstractly interpret a simple programming language via
modification of security levels of variables. Our approach
is sound and compositional and results in an algorithm for
statically checking confidentiality
