In the security mechanism of distributed wireless sensor network, key management plays a fundamental role. Because the distributed wireless sensor network has a large scale, its node resource is very limited and distributed, key management mechanism of traditional wireless network is not suitable for it. Therefore, a security mechanism based on the combination of elliptic curve cryptosystem and public key is proposed, which realizes safe key establishment and certification. The security of the protocol is analyzed. Energy consumption of the proposed key establishment scheme is simulated and the results show that this protocol is feasible to be applied to wireless sensor
networks.
