| Popis: | In wireless sensor networks, ensuring secured exchanges during deployment taking into account constraints such as optimal use of resources has to be considered seriously. Usually, initial exchanges require the calculation of a secret key using ECDH with authority certification or implementing ECDSA algorithms for signature implying heavy calculations and several transmissions between sensor nodes. In this paper, we propose a new mechanism for public keys management using an elliptic curves cryptosystem where the objective is to optimize treatments by reducing significantly the calculation of scalar multiplications. Thus, public keys exchange mechanism allows a partial communication by transmitting simply the abscise and the LSB of the ordinate of the elliptic curve point totaling 161 bits instead of 320 bits. In order to show advantages of our contribution, we compare its performances in terms of execution time and implementation to ECDH, ECDSA and ECIES by performing real tests on a TMote Sky sensor. |
