Abstract: This paper analyzes the application of public key technology such as elliptic curve in Wireless Sensor Networks(WSN). It introduces the structure of WSN operating system named TinyOS, the development flow of NesC program and the TinyOS based Elliptic Curve Cryptography(ECC) cryptolib named TinyECC. It uses TinyECC to design and implement a light node authentication protocol based on ECC. Analysis results validate that this protocol is feasible in WSN.

Key words: Wireless Sensor Networks(WSN), Elliptic Curve Cryptography(ECC), identity authentication protocol
