A Trust-Table Propagation Model to Avoid Transmission through Malicious Communication Nodes

A novel idea for offering a high level of authenticity in data communication has been proposed in this paper.This idea can be coincided by maintaining the transmission of data through highly reputable nodes.A Trust table that measures the authenticity of the end-to-end paths from any node to the various destinations is stored within the communication nodes along with routing tables.Dynamic changes in nodes' authenticities, which are almost due to malicious intrusion, are conceived by periodically propagating discovery packets through the whole network in all directions.Any route that turns unauthentic will be avoided in the upcoming communication operations.When the route is recovered, the trust table will promptly be updated to return this route to used again.The proposed method introduced promising results in dealing with dynamic authenticity changes in nodes.Fast responsive performance was also clearly noticeable in results.
