Abstract :
Sensor nodes have limited computing power and memory sizes. Sometimes, they are used in applications that require sending rapidly secure data to a remote control center. Therefore, they require lightweight techniques to accomplish this task. In this paper, we used Elliptical Curve Cryptography (ECC) for data encryption because ECC could create smaller and more efficient cryptographic keys compared to other cryptographic techniques such as RSA. We used specific algorithms to improve scalar multiplication time in spite of energy consumption. Moreover, we proposed a distributed scheme to enhance more the data delivery time from a source node to the base station by involving neighbors in the calculation. The results of experiments on TelosB motes showed considerable improvement of data delivery time.
