MITE: Memory integrity based trust evaluation in Wireless Sensor Networks

Trust is quintessential to safety in a network and is the epitome of security. Trust management schemes have been researched and implemented in Wireless Sensor Networks (WSNs) to provide an added advantage over and above the cryptographic security mechanisms. Each trust management scheme deals with the concept of trust and its evaluation in a unique manner. This uniqueness in approach is achieved by using network parameters, QoS, behavior of nodes etc. as metrics to evaluate trust. Every trust management scheme aims at providing resilience to the effect of malicious or selfish nodes. In this paper, we propose a node memory based trust evaluation method by using memory integrity as a metric to evaluate trust. The results indicate the method to be promising to evaluate trust at node-level and network-level.
