Abstract
Wireless sensor networks are envisaged in military, commercial and healthcare applications, where data security is an important aspect. Security of the data in the network is based on the cryptographic technique and the way in which encryption and decryption keys are established among the nodes. Managing the keys in the network includes node authentication, key agreement and key update phases which poses an additional overhead on network resources. Both Symmetric and Asymmetric key techniques when applied separately in WSN fails to provide a scheme suitable for wide range of applications. Hybrid key management scheme is scalable alternative to match security requirements of WSN with minimum overhead on available resources. Heterogeneous WSN is considered in which ID based key establishment and polynomial based key pre-distribution scheme are proposed for higher and lower level of hierarchy respectively. The results of the proposed hybrid key management scheme indicate reduced resource overhead and improved security level.
