| Abstract: | The rapid development of wireless sensor networks motivates the researchers and industries to implement large scale wireless sensor network in highly sensitive applications. Since the data aggregation is the major functionality of the wireless sensor network, the network implementation should avoid data aggregation issues like energy, collision, delay and security. As sensor nodes are deployed in hostile environments, the security of the sensitive information such as authenticity, confidentiality and integrity should be considered. To provide a unique solution that resolve the security and energy issues, this paper proposes a hybrid secure data aggregation (HSDA) to provide high secure data aggregation in an energy efficient way. HSDA implements an end to end symmetric key cryptography for secure authentication using shared public key and it uses hop by hop asymmetric key cryptography with the private keys of each node for data integrity and confidentiality. The proposed model performs the private key generation and encryption at the leaf node to reduce the communication and computation overhead of the sensor nodes. The proposed energy efficient way for achieving the secure data aggregation is proved through simulation results. Compared with existing models, the proposed model provides a new solution that resolves energy as well as security issues in data aggregation. [ABSTRACT FROM AUTHOR] |
