Establishing Trust in Multiagent Environments: Realizing the Comprehensive Trust Management Dream
نویسندگان
چکیده
In this paper, we present a framework for enabling agents in multiagent systems to engender trust from the other agents in the environment. Opposite to the aims of most existing trust modelling research, our algorithms serve to guide the actions of trustees (instead of trustors). Our approach requires trustees to predict the types of the trustors, modifying their behaviour when predictions prove to be inaccurate. The primary aim of trustees is to acquire high levels of trust, of value for future interactions with trustors. Illustrated in the context of electronic marketplaces, we offer a validation of our approach in comparison with competing algorithms that drive the behaviour of trustees which are more focused on immediate rewards. Through simulations, we are able to demonstrate important gains achieved by our approach. As such, we offer an important first step in addressing a novel challenge for trust modelling, articulating how trust may be successfully engendered.

Comprehensive trust management
Trust has been viewed as an integral component of agent decision making in the context of multiagent systems (MASs). Various formal and semi-formal trust schemes, motivated by diverse considerations and influenced by various fields of study, have been proposed, implemented, and evaluated. We believe that there still exists a pressing need for developing a comprehensive trust management scheme t...

The development of complex applications that use the Peer-to-Peer computing model is restrained by security and trust management concerns, despite evident performance benefits. An example of such an application of P2P computing is P2P Massive Multi-user Online Games, where cheating by players is simple without centralized control or specialized trust management mechanisms. The article presents ...
متن کاملA comprehensive approach to trust management
Trust has been recognized as a key component of agent decision making in the context of multiagent systems (MASs). Though diverse trust models and mechanisms, influenced by various fields of study, have been proposed, implemented, and evaluated, we believe that the literature has ignored key aspects of pragmatic and holistic trust based reasoning. In particular, the focus of trust research has ...
متن کاملDisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems
The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...
متن کاملDelegations and Trust
One of the fundamental notions in a multiagent system is that of delegation. Delegation forms the foundation for cooperation and collaboration among the members of a multiagent system. In diverse environments such as those formed by open multiagent systems, the various members constituting the environment are customarily alien to one another. Delegation decisions in such environments are necess...
