Properties, which have long been used for reasoning about systems, are sets of traces. Hyperproperties, introduced here, are sets of properties. Hyperproperties can express securi...
The reason for using distributed constraint satisfaction algorithms is often to allow agents to find a solution while revealing as little as possible about their variables and co...
Modal Transition Systems (MTS) are operational models that distinguish between required and proscribed behaviour of the system to be and behaviour which it is not yet known whethe...
In this paper, we propose a reputation-based trust model for P2P applications and study it a security framework. This framework makes it easy to reason about the resilience of the...
Accurate failure prediction in Grids is critical for reasoning about QoS guarantees such as job completion time and availability. Statistical methods can be used but they suffer f...
