Abstract

With the rapid development of smart grid technology, load control techniques have also advanced swiftly. However, ensuring the security and confidentiality of load control systems, particularly achieving secure communication between the Power Load Management System (PLS) and the Load Control Terminal (LCT), poses a highly challenging issue. To address this, this paper proposes an anonymous identity authentication and re-authentication scheme based on quantum random numbers. This scheme ensures the security and privacy of identity authentication between PLS and LCT in various scenarios, significantly reducing the computational and communication overheads required for authentication by 66% compared to existing solutions. Finally, we employ BAN logic to formally verify the security of this scheme.

Lightweight Quantum-Key-Enhanced Security Scheme for Power Load Control Systems

Wei Liu, Hai Wang, Gang Sun +3 more

This paper presents a security solution for power load control systems by integrating quantum key technology to address the security challenges encountered by traditional encryption methods in power systems. Conventional identity authentication and key exchange schemes often depend on pseudorandom number generators, which are susceptible to various attacks. The proposed scheme leverages quantum random number generation combined with symmetric encryption techniques to design an anonymous authentication protocol, aimed at safeguarding data transmission and load control processes within the power system. Specifically, the scheme includes a three-phase registration process and a two-phase authentication process to ensure secure communication between the Power Load Management System (PLS) and the Quantum Secure Load Control Terminal (QLT). During the registration phase, the PLS registers with the quantum key center, while the QLT registers with the quantum key center via the PLS. In the authentication phase, the scheme supports initial and rapid re-authentication using quantum keys and pseudonym technology to prevent identity spoofing, data tampering, and replay attacks. Experimental results demonstrate that the proposed scheme maintains high security while offering reduced computational overhead and increased efficiency, making it well-suited for resource-constrained power system environments.

Lightweight Quantum Authentication and Key Agreement Scheme in the Smart Grid Environment

Zehui Jiang, Runhua Shi

Smart grids leverage smart terminal devices to collect information from the user side, achieving accurate load forecasting and optimized dispatching of power systems, effectively improving power supply efficiency and reliability while reducing energy consumption. However, the development of quantum technology poses severe challenges to the communication security of smart grids that rely on traditional cryptography. To address this security risk in the quantum era, this paper draws on the core idea of quantum private comparison and proposes a quantum-secure identity authentication and key agreement scheme suitable for smart grids. This scheme uses Bell states as quantum resources, combines hash functions and XOR operations, and can adapt to resource-constrained terminal devices. Through a security proof, it verifies the scheme's ability to resist various attacks; the experimental results further show that the scheme still has good robustness in different noise environments, providing a feasible technical path for the secure communication of smart grids in the quantum environment and having clear practical engineering value.

Efficient Anonymous Authentication and Group Key Distribution Scheme Based on Quantum Random Numbers for VANETs

Teng Cheng, Qiang Liu, Qin Shi +4 more

Near-field communication in VANETs can effectively reduce communication overhead compared to peer-to-peer communication. However, there is still plenty of room for improvements to be made to ensure identity authentication privacy protection and to enhance the security and efficiency of key distributions during transmissions. Therefore, this paper proposes an anonymous identity authentication and group key distribution scheme based on quantum random numbers. In the proposed scheme, (1) anonymous credentials for vehicles are generated by a combination of random numbers on the vehicle side and random numbers in the TA, and mutual recognition of vehicles and roadside identity is achieved through the TA in the form of zero-knowledge proof, which achieves privacy protection for the vehicle during authentication. (2) A combined key generation method was devised. The roadside and the TA in this case jointly generate the group key. The TA uses a previously filled quantum key to encrypt the group session key parameter GSPc generated by its quantum random number generator to ensure security, and the roadside obtains the group session key parameter GSPr by calculating the anonymous credentials of all legitimate vehicles to achieve fast updates of the group session key. This scheme achieves forward and backward security while guaranteeing one-at-a-time encryption. The signaling and computation overheads were calculated, and the signaling overhead was reduced by nearly half. In addition, the group key issuance time was significantly reduced compared with other schemes. Through formal security analysis and experimental verification, the security and feasibility of this protocol were proved.

Quantum-Safe and Cross-Layer Authentication and Key Agreement Protocol for Smart Grid Communications

Cong Pu, Muhammad Abdullah Bilal, Sunho Lim

The extensive value and importance of smart grids are evident in their transformative impact on sustainable urban development. However, the swift progression of quantum computing has made the security and privacy of smart grid communications a pressing and vital issue. Although considerable studies have been carried out on authentication and key agreement within smart grids, the predominant body of solutions either come with substantial computation, communication, and storage overheads, or are primarily single-layer schemes. More importantly, they are not designed to withstand advanced quantum attacks. In this paper, we propose a novel quantum-safe and cross-layer authentication and key agreement protocol, named QCLaka, for smart grid communications that overcomes the shortcomings of existing approaches and offers advanced security and functionality features. The proposed QCLakaprotocol integrates lattice-based cryptography with probability physical unclonable function (Prob-PUF) to enable the local gateway and the smart meter to mutually authenticate each other and establish a secure session key. The security of the proposed QCLakaprotocol is assessed through formal security verification to highlight its safety in adversarial environments and its ability to withstand both well-known and advanced cyberattacks. Additionally, the experimental evaluation shows that the proposed QCLakaprotocol outperforms the benchmark schemes regarding the performance in security and efficiency.
