The salient features of WSN like use of wireless radio communication, collaborative nature and deployment in the open environment exposes it to many security threats. Since WSN has tight limitations on the power consumption, transmission and computation the complex cryptographic algorithms can't be used to provide the security. Key management in WSN is the fundamental line of defense for a secure communication and thus it is very important. In this paper, the authors propose a new framework for enhanced key management for hierarchical WSN which enhances the security of the network.
