Future-Proofing Digital Trust: From Classical to Quantum-Safe Security

Dear Colleagues,

With the rapid advancement of quantum computing technology, traditional asymmetric encryption schemes like RSA and ECC face an existential threat. To maintain the cornerstone of the digital economy in 2025 and beyond, the paradigm of "Digital Trust" must transition from classical cryptographic defenses to Quantum-Resistant (QR) architectures.

This Topic aims to explore the critical challenges and opportunities in the global migration process toward Post-Quantum Cryptography (PQC). The focus extends beyond merely developing new mathematical algorithms; it emphasizes ensuring a smooth transition and long-term resilience for existing critical infrastructure, such as IoT networks, financial systems, and cloud platforms. We welcome original research and review articles on PQC implementation, crypto-agility, the design of Quantum-Resistant protocols, and the optimization of hardware security modules. Through an interdisciplinary lens, this Topic is dedicated to building a secure and reliable digital trust framework that withstands the quantum era.

We look forward to your valuable contributions!
