The secure authenticated key establishment between.nodes in Wireless Sensor Networks (WSNs) has not been fully.solved in the existing schemes. It’s a good idea to apply the.Diffie-Hellman protocol to address it perfectly, but the existing.authenticated Diffie-Hellman (ADH) protocols are not perfect.because their authentication are partial or delayed. In this paper,.we first present a concept of full authentication and propose a new.fully authenticated Diffie-Hellman (FADH) prototype with lightcertificate-.based authentication. And then based on the theory.of elliptic curve cryptography, we construct the TinyADH (Tiny.Authenticated Diffie-Hellman) protocol with applying the FADH.in WSNs. Compared with the existing similar solutions, TinyADH.has lower communication overload, is easier to implement into.existing standards, and more secure under equivalent computational.complexity. The experimental results show that using.this scheme for a successful key agreement between two nodes.averagely takes about 54 seconds on TelosB. Moreover, the simulation.results indicate that repeated key agreement can improve.the secure connectivity rate. However, considering the cost.performance ratio, it is advisable to take 2 runs of the negotiation.
