Beyond the Breaker: Evaluating Post-Quantum Cryptographic Algorithms for Practical Smart Grid Deployment

Jacob Rydecki, Gaurav Panwar, Olga Lavrova

With the advancement of quantum computing, traditional public-key cryptographic algorithms are increasingly at risk of being broken. This paper investigates the applicability of post-quantum cryptography (PQC) within modernized power grid infrastructures, commonly known as smart grids, that rely heavily on interconnected and sometimes internet-facing devices and distributed control systems. To help safeguard these critical infrastructures against quantum-enabled threats, we benchmark and evaluate the performance of NIST-standardized and finalist PQC Key Encapsulation Mechanisms (KEMs) in a realistic smart grid testbed. Our evaluation includes both benchmarking of core cryptographic operations, key generation, encapsulation, and decapsulation, as well as full TLS 1.3 handshake benchmarking across a real network of embedded devices and smart grid nodes. A key contribution of this work is the development of a smart grid testbed spanning multiple buildings with distributed energy resources (DERs) such as batteries and photovoltaic arrays, enabling an in-depth, system-level evaluation of post-quantum key exchange protocols in this context. We conclude by discussing the trade-offs between algorithmic efficiency and system constraints such as bandwidth, key rotation frequency, and device capability. Our findings offer actionable recommendations for the deployment of PQC algorithms tailored to the smart grid.

Lightweight Post-Quantum Authentication and Key Agreement Protocol for Secure Smart Home IoT Control

Wad Ghaban

As smart home devices become more widely available, their limited resources and potential exposure to various types of cyber-attacks make it difficult for the traditional security protocols to remain effective. Cloud-enabled smart home IoT platforms have helped to improve device intelligence and overall efficiency when controlling them, but the additional use of cloud computing has also created additional complexity in controlling these devices through user-defined automated rules and remote access via vendor apps. Conventional security schemes do not consider these types of control models, nor do they provide a reasonable balance of the additional computational overhead introduced, the efficiency of communications, and the level of security provided. Additionally, with the introduction of quantum computing, current public key cryptography primitives will become obsolete, necessitating the requirement for an adoption of post-quantum security measures. To overcome these issues, this paper presents a proposal for a lightweight mutual authentication and key agreement scheme that employs post-quantum cryptography primitives to facilitate a secure interaction between the user’s cloud platforms, smart home devices, and the user. The protocol also supports remote secure control, while providing the resistance to both classical and quantum attacks. The proposed protocol has been thoroughly evaluated through formal verification using the ProVerif tool and multiple heuristic evaluation techniques. Additionally, the security features of the proposed protocol have been compared to those of several existing methods, providing evidence that it offers improved security features, forward secrecy, and quantum resistance while maintaining a lightweight profile compatible with the limitations of modern smart homes.
