Special Issue Information

Dear Colleagues,

In the era of digital transformation, cloud computing has become the backbone of modern IT infrastructure while simultaneously introducing complex security challenges. The convergence of cryptographic techniques, data protection mechanisms, and cloud architectures has emerged as a critical research domain. Recent advances in quantum computing, AI-driven attacks, and sophisticated malware demand fundamentally new approaches to secure cloud ecosystems while maintaining performance and scalability.

Current security solutions face some fundamental limitations; for example, traditional cryptographic methods are becoming vulnerable to quantum attacks, existing access control models cannot adequately address dynamic cloud environments, and privacy-preserving computation techniques often impose impractical performance overhead. These challenges are further exacerbated by the expanding attack surface created by hybrid cloud deployments and edge computing paradigms.

We invite researchers and practitioners to submit original contributions and review articles exploring the intersection of cryptography, data security, and cloud computing. High-quality research papers addressing theoretical advancements, practical implementations, and emerging challenges in securing cloud-based systems are welcome.

In Social Internet of Vehicles (SIoV) environments, fog computing plays a crucial role in supporting real-time services by reducing the latency inherent in cloud-based architectures. However, fog nodes are typically deployed in physically exposed roadside environments and can be operated by several system operators, making them vulnerable to physical compromise and unauthorized access. Despite these threats, many existing authentication schemes assume fog nodes to be fully trusted or honest-but-curious, allowing them to decrypt transmitted data using a session key shared among vehicles, fog nodes, and cloud servers. To overcome these limitations, this paper proposes a quantum-secure pairwise key agreement scheme that establishes distinct session keys for vehicle–fog, fog–cloud, and vehicle–cloud communications. This design effectively prevents the disclosure of sensitive information even in the event of fog node compromise. Furthermore, Physical Unclonable Functions (PUFs) are employed to mitigate physical capture attacks, while lattice-based cryptography based on the Module Learning with Errors (MLWE) problem is integrated to ensure resistance against quantum computing attacks. The security of the proposed protocol is rigorously validated through formal analysis using AVISPA, BAN logic, and the Real-or-Random (RoR) model, in addition to informal security analysis. Comparative performance evaluations against related schemes demonstrate that the proposed approach achieves a balance between efficiency and security, making it well suited for practical deployment in SIoV environments.
