The study and application of elliptic curve cryptography library on wireless sensor network

Information security on WSN is an open and hot area. Firstly, this paper briefly introduces the structure of WSN operating system TinyOs, the flow of Nesc program and the elliptic curve cryptography library TinyECC. On the basis of TinyOs platform and TinyECC, this paper designs and implements a lightweight node authentication protocol. Finally, this paper analyzes its test result and proves its feasibility.
