Sub-delegation and trust
نویسندگان
چکیده
We investigate trust propagation in delegation situations, which often occur in hierarchical organisations and coalition structures. In doing so we define a delegation chain representing the sub-delegation process. Such delegation chains present a problem for current trust evaluation mechanisms, which are unable to accurately divide trust among the chain members, resulting in degraded system performance. In this paper we investigate the effects of sub-delegation on a probabilistic trust model and propose a model of weighting trust updates based on shared responsibility. We evaluate this model in the context of a simulated multi-agent system and describe how different weighting strategies can affect probabilistic trust updates when sub-delegation is possible.

Sub - delegation and Trust ( Extended
Trust mechanisms can allow an agent to identify the most trustworthy entity to which a task should be delegated. Now this entity may further delegate the task, ultimately resulting in a delegation chain representing the sub-delegation process. Such delegation chains present a problem for current trust evaluation mechanisms, as they typically which reward or penalise a single agent rather than s...
متن کاملEfficient Task Sub-Delegation for Crowdsourcing
Reputation-based approaches allow a crowdsourcing system to identify reliable workers to whom tasks can be delegated. In crowdsourcing systems that can be modeled as multi-agent trust networks consist of resource constrained trustee agents (i.e., workers), workers may need to further sub-delegate tasks to others if they determine that they cannot complete all pending tasks before the stipulated...
متن کاملUsing Trust for Restricted Delegation in Grid Environments
Delegation is an important tool for authorization in large distributed environments. However, current delegation mechanisms used in emerging Grids have problems to allow for flexible and secure delegation. This paper presents a framework to realize restricted delegation using a specific attribute certificate with trust value in grid environments. The framework employs attribute certificates to ...
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...

In emerging ubiquitous computing, related nomadic users often perform similar tasks and share the same computing infrastructure. This means that security of the shared resources is of prime importance. Frequent delegation of tasks among users must be anticipated as most nomadic environments are hectic and very dynamic. A delegation mechanism with a slightly complicated user interface will not o...
