The rapid progress of quantum computing poses significant challenges to traditional cryptographic mechanisms, necessitating the adoption of post-quantum cryptography (PQC) solutions. This paper proposes a Quantum-Enhanced Security for Smart Meters (QESM) system to protect power plant data in smart cities, integrating Kyber for secure key exchange, FALCON (Fast-Fourier Transform over Lattice-based Cryptography) for quantum-resistant digital signatures, and ZKP (Zero-Knowledge Proof) for effective verification without revealing sensitive data to secure power plant data against quantum attacks. To evaluate the security of the proposed system, we analyze its resistance to various quantum threats, including Shor’s algorithm, Grover’s algorithm, quantum key analysis, quantum reversal encryption, quantum amplification, quantum switching, and quantum collision attacks. In the current study, accurate measures were used and the average was approximately 7.065 (bits/byte) for randomness, the average execution time was 6.202 milliseconds, the average memory consumption was approximately 4.343 KB, 6.4 Completeness was equal to 1 and unforgeability was 100%. As for the average throughput, it was approximately 485,605 operations per second. That shows the QESM system provides strong security and efficiency, making it a viable solution for protecting the electricity infrastructure in smart cities in the quantum era.

Securing big data in power plants is an important and fundamental step in the infrastructure of smart cities. In addition, it becomes a barrier if it is not controlled from the beginning. Security must be a combination of fast and robust properties. This research presents a traffic security system (TSS) in a smart city (SC). It is a novel paradigm meant to improve data security and integrity by means of a multilayered method. Advanced fault analysis, dual-stage pseudonymizing, quantum key distribution via the BB84 protocol, and Falcon signatures (FS) are combined in the proposed system. TSS enhances data security by enhancing privacy, supporting resilience against quantum computing threats, and not burdening the network with complex and large keys. The proposed system has been tested against several recently known attacks, such as replay, supply chain, Sybil, blackhole, eavesdropping, advanced persistent threat (APT), tampering, ransomware identity fraud, and desynchronization, and it has been proven to overcome them. In terms of performance evaluation, the average signing time was approximately 0.002 milliseconds. In comparison, the average signature verification time was approximately 0.004 milliseconds, with an average execution time of approximately 0.54 milliseconds and a precision of approximately 93.6 %, a recall of approximately 97.8 %, and an F1_score of approximately 95.6 %, which are considered low compared with those of state-of-the-art research. Thus, the proposed TSS system is highly acceptable for power plant applications. This work lays the groundwork for future developments in safe, privacy-conscious urban systems by presenting a multilayered approach to secure energy data in smart cities.
The increasing integration of smart grids within the Internet of Things (IoT) ecosystem requires the implementation of robust security measures due to vulnerabilities brought about by pervasive connectivity. Previous smart grid security protocols are based on classical cryptographic algorithms, which are susceptible to significant threats from emerging quantum computers. Consequently, the adoption of quantum-resistant solutions is imperative for the long-term security of smart grids. This article presents a novel protocol for authentication and secret key establishment in smart grids, utilizing post-quantum cryptography (PQC) algorithms. Our proposed protocol employs the FALCON digital signature algorithm for integrity verification and the CRYSTALS-Kyber key encapsulation mechanism (KEM) for secret key establishment, providing robust protection against quantum attacks. Our optimized implementation of the proposed protocol on a graphics processing unit (GPU) targets grid security module (GSM)/gateway-side deployments and demonstrates scalability under large numbers of concurrent authentication requests. Experimental validation demonstrates the proposed protocol’s ability to effectively manage numerous concurrent authentication requests, ensuring secure and efficient communication within smart grid networks.

The proposed system has been tested against several recently known attacks, such as replay attacks, Sybil attacks, eavesdropping, advanced ransomware attacks, social engineering attacks, and critical infrastructure attacks, and it has been proven to overcome them. In terms of performance evaluation, we obtained an average signature time of about 0.004 MS, an average signature verification time of about 0.006 MS, an average execution time of 0.66 MS, a precision of 96%, a recall of 95%, and an F1-score of 96%, which are good compared to the state-of-the-art research. Thus, our proposed system is highly acceptable for power plant applications.
