A node authentication protocol based on ECC in WSN

This paper improves an authentication protocol based on The Elliptic curve Cryptography, and applies it to WSNs. This scheme contains system initialization, node registration and authentication phase. It continues to use the primary scheme's high efficient multiplication operation method, and the sensor node store the other ID's hash value as the premise of the authentication. Besides, this scheme increases an authentication phase between sensor nodes using The XKAS Key Agreement Scheme. Conclusion shows that the improved agreement has lower consumption for wireless sensor network.
