Abstract
For autonomic computing systems that utilize mobile agents and ant colony algorithms for their sensor layer, trust management is important for the acceptance of the mobile agent sensors and to protect the system from malicious behavior by insiders and entities that have penetrated network defenses. However, certain characteristics of the mobile agent ant swarm – their lightweight, ephemeral nature and indirect communication – make the design of a trust management model for them especially challenging. This thesis examines the trust relationships, issues, and opportunities in a representative system, assesses the applicability of trust management research as it has been applied to architectures with similar characteristics, and finds that by monitoring the trustworthiness of the autonomic managers rather than the swarming sensors, the trust management problem becomes much more scalable and still serves to protect the swarm. This thesis then proposes the DualTrust conceptual trust model. By addressing the autonomic manager’s bi-directional primary relationships in the ACS architecture, DualTrust is able to monitor the trustworthiness of the autonomic managers, protect the sensor swarm in a scalable manner, and provide global trust awareness for the orchestrating autonomic manager.
