Abstract: Identity cryptography has been widely used in Security Authentication. Bilinear pairing is an important tool for constructing the cryptography developed in recent years. Based on the research of the bilinear pairing, this paper proposed a standard identity-based authentication protocol. This protocol is secure against impersonation under passive attack and has high efficiency. This paper also implemented the authentication protocol in the platform of TinyOs. Finally,the simulation results show that the authentication protocol is effective in the wireless sensor network.
