A new kind of session keys based on message scheme for sensor networks

In order to achieve security in wireless sensor networks (WSN), it is important to encrypt message, but these sensor node resource constraints, key management in WSN, recently, usually uses some key pre-distributed scheme or session key scheme to achieve security. In this paper, we propose a new rekeying management for group sensor nodes, which is based on message between group neighbor nodes. Our scheme exhibits a nice power efficient and excellent updating communications keys in terms of energy efficient, communication cost, security, and computational overhead.
