In this paper, an efficient key management scheme based on public key elliptic curves signcryption scheme for Heterogeneous sensor networks has been proposed. The proposed protocol is optimized for cluster sensor networks and is efficient in terms of complexity, number of message exchange, computation, and storage requirements with optimized security benefits for clustered environment. The proposed key management possesses not only confidentiality but also characteristics like unforgeability and non repudiation.
