Abstract:

For the safety and efficiency of identity authentication protocol in Wireless Sensor Network (WSN) , this paper proposes a WSN identity authentication protocol based on HECC. The new WSN identity authentication protocol includes the initialization phase and authentication phase, and in the authentication phase a sign of hyperelliptic curve method is used to implement two-way identity authentication and information exchange between the nodes. Through the proof of the correctness and security of the protocol, the protocol is confidentiality, shall not forge, non-repudiation, forward security and public verifiability. Finally the implementation efficiency of the protocol is analyzed and compared, and the results show that the protocol is suitable for the identity authentication in WSN which the resources are limited.

Key words: wireless sensor network, identity authentication protocol, HECC, signcryption, two-way identity authentication
