Evaluation of Network Trust Using Provenance Based on Distributed Local Intelligence
Provenance can play a significant role in a military information system for supporting the calculation of information trust. A node's trust can change over time after its initial deployment due to various reasons such as energy loss, environmental conditions or exhausting sources. The authors introduce a node-level trust-enhancing mechanism for information networks using provenance. A unique characteristic of the proposed trust architecture presented here is the use of provenance through the path of the information from source to destination in determining the information trust. In this proposed architecture each node in the system has a trust and provenance vector. Each information item transmitted over the network has a trust value associated with it.
