We present tools to support model-based security engineering on both the model and the code level. In the approach supported by these tools, one firstly specifies the securitycr...
This paper describes a security architecture designed to support role-based access control for distributed object systems in a large-scale, multi-organisational enterprise in whic...
Probabilistic model checking is a formal verification framework for systems which exhibit stochastic behaviour. It has been successfully applied to a wide range of domains, includ...
Policy testing and analysis are important techniques for high assurance of correct specification of access control policies. We propose a set of testing and analysis techniques fo...
Developing network protocols for mobile wireless systems is a complex task, and most of the existing simulator frameworks are not well suited for experimental development. The YAE...
