【Registration Open】2026 International Workshop on Post-Quantum Cryptography Frontiers and Applications
— Ushering in the PQC Migration Year One, Building a “Real-World” Cryptographic Defense Line
The rapid development of quantum computing is pushing traditional public-key cryptography to the brink of collapse. With the official release of the NIST Post-Quantum Cryptography (PQC) standards, global cybersecurity has entered a critical phase of “migration and deployment.” In this era of transformation, how do we move from theoretical algorithms to engineering practice? How can a secure post-quantum defense line be deployed in real hardware environments?We sincerely invite you to attend the “2026 International Workshop on Post-Quantum Cryptography Frontiers and Applications” to be held at Xi’an Jiaotong-Liverpool University (XJTLU) in Suzhou. This four-day event (March 3 to March 6, 2026) brings together leading figures and practical experts in the field of post-quantum cryptography, aiming to bridge the gap between academic theory and industrial application.
This workshop has specially invited Professor Jintai Ding, a core designer of the NIST PQC standards, and Dr Markku-Juhani O. Saarinen, a globally renowned expert in PQC engineering, to co-lecture. The conference will centre on the core theme of “Real-World Post-Quantum Cryptography,” not only covering the principles of mainstream algorithms such as lattice-based cryptography, hash-based signatures, and code-based cryptography, but also delving into engineering pain points like hardware acceleration, side-channel defense, RISC-V architecture support, and internet protocol migration.
