Since wireless sensor network applications are ever growing in scale and complexity, managers require strong formal guarantees that any changes done to the system can be enacted safely. This paper presents the formalisation and analysis of the semantics of policies, tiny software artefacts used to orchestrate wireless sensor network applications. The(More)
A fully abstract compiler prevents security features of the source language from being bypassed by an attacker operating at the target language level. Unfortunately, developing fully abstract compilers is very complex, and it is even more so when the target language is an untyped assembly language. To provide a fully abstract compiler that targets untyped(More)
A fully abstract compilation scheme prevents the security features of the high-level language from being bypassed by an attacker operating at a particular lower level. This paper presents a fully abstract compilation scheme from a realistic object-oriented language with dynamic memory allocation, cross-package inheritance, exceptions and inner classes to(More)
This paper investigates ownership types in a concurrent setting using the Join calculus as the model of processes. Ownership types have the effect of statically preventing certain communication, and can block the accidental or malicious leakage of secrets. Intuitively, a channel defines a boundary and forbids access to its inside from outer channels, thus(More)
A compiler is fully-abstract if the compilation from source language programs to target language programs reflects and preserves behavioural equivalence. Such compilers have important security benefits, as they limit the power of an attacker interacting with the program in the target language to that of an attacker interacting with the program in the source(More)
