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 (2m) in order to obtain stronger
cryptography. In our approach we are using Koblitz curves and
TNAF ( τ - 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.

Can i get the source code in matlab..? or can you send me the code to my mail id(prapunreddy93[at]gmail.com) Plz...

Implementation of Diffie-Hellman Key Exchange on Wireless Sensor Using Elliptic Curv

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 (2m) in order to obtain stronger cryptography. In our approach we are using Koblitz curves and TNAF (pi-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.
