It is noted that the Wireless Sensor Networks (WSN) based on the rapid progress of wireless communications and embedded micro electro mechanical systems technologies are becoming important part in people daily life. However, the security of the WSN becomes one of the major concerns in its applications. Even Elliptic Curve Cryptography (ECC) prominently offers great potential benefits for WSN security there is still a lot of work needs to be done due to WSN has very restraint running conditions such as limited energy source, capability of computing, etc. Also it is well known that scalar multiplication operation in ECC accounts for about 80% of key calculation time on wireless sensor network motes.
