Security Model for Hierarchical Clustered Wireless Sensor Networks
The proposed security system for the Wireless Sensor Network (WSN) is based on the WSN security design goal that 'To design a completely secure WSN, security must be integrated into every node of the system'. This paper discusses on two main components of the security framework viz. the secure key management module and the secure routing scheme. The incorporation of security mechanism during the routing protocol design phase is the main focus of this paper.
