Abstract

Wireless Sensor Networks are deployed in an area where the humans are not able to access, security becomes more important because they are prone to many types of attacks. WSNs are more susceptible to attacks mainly due to the nature of their deployment and the mode of communication. The proposed model is a light weight security scheme capable of maintaining all the security features such as confidentiality, integrity and protection against replay attack. The proposed model aims to prevent replay attack and provides integrity within the network by sending query to every phase of communication. To provide replay attack protection, an extended model known as MSQPS (Modified Secure Query Processing Scheme) is used. In MSQPS, once the network starts to process a query no new node can join the network until the query is processed. MSQPS provides security to the stored data in nodes and the communication among the nodes. The limitation is that the probability of attacking cluster head and the member nodes is higher than attacking the base station. In all communication between the cluster heads and member nodes the key is neither transmitted nor pre-deployed. It protects the replay attack and provides the basic security features such as the confidentiality and integrity. The performance of the scheme is evaluated through data freshness, authentication rate and packet delivery ratio and so it provides better integrity level.
