Efficient and Secure Data Aggregation Scheme for Wireless Body Area Network

The growth of Wireless Body Area Networks (WBANs) has become an integral part of electronic healthcare systems. WBANs use sensors to continuously collect patient data for health monitoring, which is later transmitted to a remote location, such as a medical server or mobile device, for record-keeping. Due to the limitations of sensors in terms of energy, power, and computational capacity, efficient data aggregation schemes are required to minimize communication overhead during data transmission in WBANs. Additionally, WBANs necessitate secure data transmission, as the records are private and confidential. In this research, we propose a secure and efficient data aggregation scheme for WBANs that utilizes a variance function for aggregation, an authentication code for secure data access, and ChaCha20 for data encryption.
