Wireless communication is inherently unreliable and can cause packets to be damaged or dropped. This unreliability in communication poses additional threats to the nodes if dropped packets are taken over by adversaries. Optimized Elliptic Curve Cryptography (O-ECC) can assist more secure towards WSN security and better protocol design. Optimized Elliptic curve cryptography is not only emerged as an attractive public key cryptosystem for mobile / wireless environments but also provides bandwidth savings. This paper presents a light security algorithm i.e. Optimized ECC which is enhancement of traditional Elliptic Curve Cryptography for wireless sensor network.
