Specifying Access Control in Event-B
(2009)Technical reportWe investigate the idea of developing access control systems in Event-B by specifying separately the "insecure" target system and the security authorisation, then combining them together in order to construct a secure system. This is based on the work by Basin et. al. [6] where the chosen language is CSP-OZ. Moreover, in order to verify the secure system against some safety temporal properties, we propose an approach of constructing several ...Report -

A Formalization of JML in the Coq Proof System
(2009)Technical reportJML is a complex specication language for Java. Its large scale and manifold features make it hard to precisely dene its semantics in a reference manual. It is thus desirable to formally specify the syntax and semantics of JML. There are many good reasons for a formalized semantics of JML in a theorem prover: It can be used to develop a sound verication condition generator for JML constructs. By formally defining the semantics in a theorem ...Report
