Implementation of elliptic curve digital signature algorithm on IRIS nodes

In order to meet the need of source authentication in a wireless sensor network composed of IRIS nodes, this paper presents the implementation and performance analysis of the elliptic curve digital signature algorithm (ECDSA) on IRIS nodes. We choose 7 kinds of optimization algorithms for ECDSA to test and compare their performance further. By turning these optimizations on or off, we compare their ROM/RAM consumption, initialization time, signature generation time and signature verification time.
