KT3F: A key-based two-tier trust management filtering scheme for intrusion detection in wireless sensor network

Abstract

The air and ambience of Wireless Sensor Network (WSN) are always suitable for intruders and they always gear up to hit this network. So the safety of WSN is very much essential and extremely challenging. Lots of intrusion detection schemes have been proposed and trust management is a significant part of them. The traditional trust management schemes were developed on the basis of calculation of trust value of nodes and provide one or few levels of intrusion detection within the network. This paper has a new Key-based Two-Tier Trust Management Filtering Scheme (KT3F), which not only allows us to spot intruder several times but also strictly filters the network by using filtering and key management scheme. By serving strict filtering, this scheme boosts the security factor much higher than the previous techniques. This approach is simple and strict filtering of network helps to mark the intruder more accurately and provides high level of security.
