ABSTRACT: As the wireless sensor
networks are easily deployable, the volume of sensor applications has been
increased widely in various fields of military and commercial areas. In order
to attain security on the data exchanged over the network, a hybrid
cryptographic mechanism which includes both symmetric and asymmetric
cryptographic functions is used. The public key cryptographic ECC security
implementation in this paper performs a matrix mapping of data’s at the points
on the elliptical curve, which are further encoded using the private symmetric
cipher cryptographic algorithm. This security enhancement with the hybrid
mechanism of ECC and symmetric cipher cryptographic scheme achieves efficiency
in energy conservation of about 7% and 4% compared to theasymmetric and symmetric cipher
security implementations in WSN.
