<p>Secure data aggregation and effective data transmission are necessary to enhance sensor network durability and performance. Secure data collection from the duty-cycled sensor nodes using a moving sink and evenly distributing the energy usage over the network is a promising solution. This work offers a dynamic path management technique to present a unique hybrid solution for energy efficiency and secure data aggregation. The goal is to minimize energy use and extend the network lifetime without compromising security. By utilizing sink mobility to dynamically optimize data collection paths, our proposed approach lowers the consumption of energy and enhances data integrity. The duty cycling mechanism is integrated to ensure the conservation of energy and optimal operation of sensor nodes extending network connectivity. The privacy, consistency of the aggregated data are guaranteed and the security of data transfer is reinforced by a lightweight encryption technique. It has been observed from the results that the proposed scheme decreases energy consumption, route construction cost, prolongs the lifespan of the network and transmits data in an encrypted form. For moving sink-based duty-cycled sensor networks, this article offers a thorough solution to the challenges related to secure data aggregation, dynamic routing, and energy efficiency.</p>
