Abstract
This work describes a low-cost Public key Cryptography (PKC) based solution for security services such as authentication as required for wireless sensor networks. We have implemented a software approach using Elliptic Curve Cryptography (ECC) over GF (2(m)) in order to obtain stronger cryptography. In our approach we are using Koblitz curves and TNAF ( tau - adic non-adjacent form) with partial reduction modulo. A Diffie-Hellman key exchange is implemented. This public key exchange is done between two participants in the network. The actual implementation is done at an 8-bit ATmega128L Micaz platform from Crossbow. Results has shown that the point calculation can be done fairly amount of time with relatively small space consumption.
