Abstract—Secure multicast has become an important component of many applications in wireless networks. In this paper, we investigate secure intra and inter group information shar...
In this paper we study the complexity of the model-checking problem for the tree logic introduced as the basis for the query language TQL [Cardelli and Ghelli, 2001]. We define tw...
Abstract. In this paper, we propose a new strategic and tactic reasoning for agent communication. This reasoning framework is specified using argumentation theory combined to a rel...
