A Security Framework for Wireless Sensor Networks

This paper presents all Overview Of the various issues and requirements of Wireless Sensor Network ('WSN') deployments. and explores the unique network architecture of WSNs and the security issues involved, It is determined that in order to provide adequate security there is a need for the integration of security services into the existing routing protocols. To this end, an extension of the 'Low-Energy Adaptive Clustering Hierarchy' ('LEACH') network routing protocol called, the 'Security Enabled - Low-Energy Adaptive Clustering Hierarchy' ('SE-LEACH') is proposed. This proposed protocol provides security services, such as data, confidentiality, key management, data integrity and data freshness in the form of a flexible and extendable framework, thereby overcoming the security issues of existing WSN protocols.
