LSDA

Abstract

The Internet of Things (IoT) is one of the most promising technologies for the near future. Healthcare and well-being will receive great benefits with the evolution of this technology. For example, the communicating objects can be body sensors, which enable a continuous real-time monitoring of vital information patients. However, due to the direct involvement to patient health information, the privacy and integrity of medical data have become a matter of much concern to the healthcare applications. In this paper, we propose the Lightweight Secure Data Aggregation (LSDA) Scheme, which is a novel secure data aggregation scheme for Healthcare using IoT. This new scheme is characterized by employing the homomorphic encryption. Also, each aggregator needs to verify all packets received from its member nodes, which can filter bogus packets in-network and thus the nodes can save energy on transmission phase. The security analysis and experimental results show that our proposed scheme guarantees patients privacy, messages authenticity, and integrity with lightweight efficiency in terms of communication overheads.
