On September 4, 2026, ExeQuantum CEO Samuel Tseitkin will present on quantum-safe security infrastructure at the Quantum Nexus Conference in Seoul, as part of a dedicated Australian Special Session organized by Quantum Australia. The presentation occurs as Korea actively deploys Post-Quantum Cryptography across eight critical sectors, energy, medical, administrative systems, telecommunications, finance, transport, defence, and space, through programs run by MSIT and KISA. This national strategy, which includes domestically developed algorithms alongside international standards, reflects a deliberate approach to standardization and sovereignty, formalized by ExeQuantum in its STAC framework: “Sovereign, Transparent, Agile, Compliant.”
Korea’s Advanced Post-Quantum Cryptography Program & Pilots
Korea is among the leading nations in preparing for a post-quantum future, actively deploying new cryptographic defenses across eight critical sectors including energy, healthcare, and finance through pilot programs initiated by the Ministry of Science and ICT (MSIT) and the Korea Internet and Security Agency (KISA). These programs, begun in 2025, initially focused on energy, medical, and administrative systems and have since expanded to encompass telecommunications, finance, transport, defence, and space infrastructure.
This broad scope demonstrates a proactive national strategy to mitigate risks posed by the eventual arrival of quantum computers capable of breaking current encryption standards. A key element of Korea’s approach is the parallel development of domestically designed post-quantum algorithms alongside adherence to internationally recognised standards like those established by the National Institute of Standards and Technology (NIST).
The KpqC Competition, completed in 2025, produced algorithms tailored to Korean infrastructure requirements and validated by both academic and governmental bodies. This strategy reflects a deliberate intent to achieve interoperability with global systems while maintaining sovereign cryptographic capabilities, a balance increasingly crucial for national security. Korea’s National Cryptographic Module Validation Program (KCMVP) now includes hybrid PQC modules, creating a formal pathway for government-wide adoption. ExeQuantum’s work addresses practical challenges in PQC migration, including the often-overlooked lack of a complete inventory of cryptographic assets within an organisation’s systems.
The company formalized its approach with the STAC framework: “Sovereign, Transparent, Agile, Compliant.” Organisations, they argue, should retain full control over their cryptographic infrastructure, ensuring auditability, algorithm flexibility, and multi-jurisdictional compliance. ExeQuantum’s Bring Your Own Database (BYOD) architecture reinforces this principle by ensuring all scan data remains within the client’s control and is never accessed or retained by the company itself.
ExeQuantum’s STAC Framework & BYOD Architecture for Sovereignty
Korea’s proactive approach to post-quantum cryptography extends beyond simply adopting international standards; the nation is actively building sovereign cryptographic capabilities alongside them. This expansion demonstrates a commitment to broad-based protection as quantum computing threats materialize. ExeQuantum also highlights how standard compilers can inadvertently introduce vulnerabilities that undermine the security of PQC algorithms. Their Jasmin/C hybrid architecture addresses this by enforcing formal verification at the assembly level. The convergence of regulatory frameworks, from NIST in the US to Korea’s MSIT/KISA programs, further underscores the urgency of a flexible and compliant approach to quantum-safe security.
