Abstract:
Many good processes exist for ensuring the integrity of software systems, Some are analysis processes that seek to confirm that cer- tain properties hold for the system, and these rely on the ability to infer a correct model of the behaviour of the software, To ensure that such inference is possible many high-integrity systems are writ- ten in "safe" language subsets that restrict the program to constructs whose behaviour is sufficiently abstract and well defined that it can be determined independent of the execution environment. This nec- essarily prevents any assumptions about the system hardware. but consequently makes it impossible to use these techniques on software that must interact with the hardware. such as device drivers. This thesis addresses this shortcoming by taking the opposite approach: if the analyst accepts absolute hardware dependence - that the analysis will only be valid for a particular target system: the hardware that the driver is intended to control -- then the specifica- tion of the system can be used to infer the behaviour of the software that interacts with it, An analysis process is developed that operates on disassembled executable files and formal system specifications to produce CSP-OZ formal models of the software's behaviour, This analysis process is implemented in a prototype called Spurinna. that is then used in conjunction with the verification tools Z2SAL, the SAL suite, and IsabelleHOL. to demonstrate the verification of prop- erties of the software.
