<p>Packaging design holds a crucial position in the product life cycle, and the issues of energy consumption and resource waste in it urgently need to be addressed. The rapid development of sensor network technology has provided a new entry point for interactive packaging design. Through real-time data monitoring and processing, it can effectively save low-carbon energy and promote sustainable development. With the application of sensor networks in interactive packaging design, the issue of network data security has become increasingly prominent, and the confidentiality, integrity and availability of data are facing severe challenges. This study designed experiments to collect energy consumption data of different packaging schemes during use and analyzed it in combination with user feedback. Aiming at the data security issues in sensor networks, various encryption algorithms, identity authentication mechanisms and privacy protection technologies have been studied. In the experiment, various network attack scenarios were simulated to test the effectiveness of the security measures proposed in this paper in preventing data leakage, tampering and replay attacks. The research results show that the interactive packaging design based on sensor networks can significantly reduce energy consumption, optimize product storage and transportation conditions, reduce resource waste, and enhance user experience. Through data feedback, enterprises can adjust packaging design in real time to improve energy efficiency. In terms of network data security, the adoption of lightweight encryption algorithms, distributed key management, and identity authentication mechanisms based on hash chains can effectively protect the confidentiality and integrity of data. The experimental results prove that the proposed security measures can resist common network attacks and protect user privacy and enterprise interests.</p>
