Korea is pursuing a sovereign, cryptography-centric defense posture by building national cryptographic capabilities that align with international standards, aiming to harden security against quantum threats.

ExeQuantum points to vulnerabilities in standard compilers for post-quantum cryptography and proposes a Jasmin/C hybrid architecture to enforce formal verification at the assembly level, addressing practical migration challenges.

ExeQuantum CEO Samuel Tseitkin will discuss quantum-safe security infrastructure at the Quantum Nexus Conference in Seoul, in early September, as part of an Australian Special Session organized by Quantum Australia.

ExeQuantum’s Bring Your Own Database approach ensures all scan data remains under the client’s control, never accessed or retained by ExeQuantum, reinforcing sovereignty over cryptographic assets.

Korea is deploying post-quantum cryptography across eight critical sectors—energy, medical, administrative systems, telecommunications, finance, transport, defence, and space—via MSIT and KISA pilots started in 2025.

ExeQuantum formalized its approach with the STAC framework—Sovereign, Transparent, Agile, Compliant—urging organizations to retain full control, ensure auditability, and meet multi-jurisdictional compliance.

Regulatory guidance from bodies like NIST and Korea’s MSIT/KISA programs underscores the urgency for a flexible, compliant, quantum-safe security strategy.

The 2025 KpqC Competition delivered Korea-tailored PQC algorithms validated by academia and government, enabling a national cryptographic module standard (KCMVP) that now includes hybrid PQC modules.
