Implementation of elliptic curve Diffie-Hellman key agreement scheme on IRIS nodes

摘要

To meet the need of key agreement and pairwise-key creation between sensors in wireless sensor network composed of IRIS nodes, this paper presents the implementation of ECDH (elliptic curve Diffie-Hellman) key agreement scheme on IRIS nodes. We choose 6 kinds of optimization algorithms for ECDH to test and compare these optimization algorithms. By turning these optimization techniques on or off, we compare the ROM/RAM consumptions, initialization time and key establishment time.
