Quantum computing is poised to transform numerous fields, with cryptography standing at the forefront. As quantum capabilities advance, it becomes imperative to rethink the foundations of secure system design for a post-quantum world. Post-Quantum Cryptography (PQC) seeks to develop cryptographic algorithms resilient against both classical and quantum adversaries, and has been an active research area for decades. In recent years, PQC has garnered substantial industrial attention, catalyzed by the standardization process initiated by the National Institute of Standards and Technology (NIST) in 2017. Following a rigorous multi-year process, NIST announced the first set of PQC standards in 2024, marking a pivotal milestone for the field.

The Workshop on Quantum-Resistant Cryptography and Security (QRSEC 2025) aims to bring together researchers, practitioners, and industry leaders to present, discuss, and advance the state of the art in quantum-safe cryptography and related areas. We invite original research papers on all aspects of quantum-resistant security, including theoretical foundations, algorithm design, cryptographic engineering, protocol development, risk assessment, and migration strategies. The workshop will also foster dialogue on the broader impact of quantum computing on cybersecurity, system security, and privacy.
