Abstract
As the espousal of smart technologies and IoT devices, such as smart grids and smart metering systems continues to grow, predominantly in smart homes—there is a rapidly rising concern over the privacy and security of users; sensitive information. Ensuring the protection of fine-grained consumer data is paramount. However, many existing security solutions struggle with computational inefficiencies and time limitations in resource-limited devices like smart meters, and persistent security vulnerabilities. Achieving secure data aggregation in smart metering systems is a substantial challenge due to the wide range of potential cyber and physical threats. This research presents various novel solutions for privacy-preserving data aggregation in both low and high frequency smart meters, based on reversible watermarking and homomorphic encryption. The proposed schemes significantly reduce the computational complexity of resource-constrained smart meters by introducing a unique Encryption Server as well as making use of the homomorphic encryption properties to secure real-time data transmission. In addition, the reversible watermarking technique used in the protocols guarantees the integrity and authenticity of data. Experimental results prove that the proposed schemes offer a privacy-friendly, secure data transmission and aggregation solution in low-frequency and high-frequency smart metering systems in a cost-effective manner.

Full-time doctoral researcher in the KISON research group at the Internet Interdisciplinary Institute (IN3) of the Universitat Oberta de Catalunya (UOC). Since 2019, she has been pursuing her doctoral studies with the support of the FPI Predoctoral Grant. The primary focus of her research is information security and privacy, especially privacy-preserving IoT-enabled smart homes using a combination of cryptographic and steganographic techniques. Her doctoral research is part of the project;GDPR-compliant consumer-facing IOT/domestic IOT;. Throughout her research career, she has contributed to several international journals and conferences with multiple research publications.
This initiative is carried out within the framework of the DANGER strategic project and the ARTEMISA chair, funded through the funds of the Recovery, Transformation and Resilience Plan, financed by the European Union (Next Generation), the project of the Spanish Government that traces the roadmap for the modernization of the Spanish economy, the recovery of economic growth and job creation, for the solid, inclusive and resilient economic reconstruction after the COVID-19 crisis, and to respond to the challenges of the next decade.
