Internet of Things (IoT) is an emerging technology that enables the interconnection between everyday objects to provide a smart environment. In near future, billions of devices equipped with sensors and actuators are expected to be connected to the Internet. Data aggregation is a practical solution to reduce the massive amount of data moving within the Internet. Moreover, the data collected by sensors can be deeply sensitive. Hence, ensuring the privacy of sensed data is highly required. However, the limited resources of sensors make the design of secure IoT mechanisms a hard and complex task. In this paper, we propose an efficient cryptographic scheme to secure aggregation and transmission of sensed data in Wireless Sensor Networks (WSNs). The proposed scheme is based on Elliptic Curve Cryptography (ECC) and Message Authentication Code (MAC) in order to provide end-to-end security. Security properties are evaluated through formal and informal analysis. The proposed scheme achieves better performance compared to a recent related work.
