Abstract—This paper introduces a mechanism for regulating the interactions between the members of an ad hoc, heterogeneous and mobile multi-agent system, in order to ensure reliable and secure coordination between them. We demonstrate this mechanism, and its importance, by describing its application to a police team whose mission is to manage (i.e., monitor and control) the traffic in an area, by operating on a set of traffic-related devices, such as draw bridges, traffic lights, and road blocks. In particular, we demonstrate how the following critical aspects of the working of such a team are provided for: a) reliable coordination between the team members; b) the ability of the leader of the team to steer its subordinates; c) reliable auditing of the operations of the team; and d) robustness of the team under certain unexpected adverse conditions, such as the unpredictable failure of the team leader. Beyond developing suitable formalisms for local regulation of actions and communications, performance tests have been conducted with the proposed implementation on the ORBIT testbed and the results presented show the viability of this approach. Keywords-Law Governed Interaction; ad hoc coordination; decentralized enforcement; security I.

Abstract. An increasing number of Internet traders exclusively sell digital products. These digital products can include media files, licenses, services, or subscriptions. We consider the concept of digital provenance in reseller chains. The goal of this work is to provide an honest customer with a guarantee on the origin and ownership history for a digital item even when the reseller they are dealing with is untrusted. Weintroducea protocol called the Tagged Transaction protocol which uses athirdparty called the Tag Generation Centre (TGC) to provide a method for honest customers to check they are purchasing a legitimate item, anonymity for customers and resellers, a method for customers to resell items they have purchased to other customers, and verification of the TGC. 1

Abstract. E-marketplace has a very important requirement of achieving mutual meaning understanding between sellers and buyers. To meet this requirement, this paper has proposed a novel SD-DSD approach, which enables to disambiguate senses between a sender and a receiver for their sent and received documents. This approach has developed five novel strategies for sense disambiguation. Based on them, new document representation models for message exchange are devised, together with their sense consistency control procedures and sense interpretation evaluation method.
