Trusted network coding framework

Abstract

Previous works on the network coding focused on applying cryptographic theorems on wireless and wired network to protect the network from the malicious packets. In this paper a new framework to create a trust model between the sink node and the source node is proposed, in which the new framework used a logistic map chaotic model within the trust approach to increase the uncertainty in the generated values. The main idea of this model is to send the chaotic code within each packet, so the sink can validate if the packet is accepted or not depending on the received code. The proposed model is divided into two phases: startup phase to initial the connection between two ends and running phase to start trust sending and trust routing to the packets. For the trust routing, new model is suggested to route the packet to the sink node and to change the status of the coding nodes. Two theoretical models are suggested to describe the behaviour of the proposed framework as follow: the knowledge packets model and the energy consumption model. After evaluating and analyzing the proposed framework using different scenarios and cases, the proposed system shows that it can achieve low overhead, low traffic, and will maximize the lifetime of the system.
