South Korea picks four home-grown post-quantum algorithms
16 JANUARY 2025, SEOUL
South Korea selected four home-grown post-quantum algorithms on 16 January 2025. AIMer and HAETAE cover digital signatures, while NTRU+ and SMAUG-T cover key establishment and public-key encryption. The choices give the country its own post-quantum options to sit alongside the international standards.
Developing national algorithms serves a strategic goal. It supports technological self-reliance and gives South Korea cryptography it controls and understands in depth, rather than depending entirely on schemes designed elsewhere. The move also diversifies the global pool of post-quantum designs, which reduces the risk that the world over-relies on any single scheme or mathematical family.
The selection gives South Korea national options rather than necessarily replacing the NIST standards. Korean organizations that operate internationally will often still need the NIST algorithms for interoperability with partners abroad. That reality keeps crypto agility valuable: systems that support more than one algorithm can satisfy both national preferences and international interoperability.
Why it matters. South Korea's choice of four home-grown algorithms signals a strategic investment in cryptographic self-reliance and adds to global diversity in post-quantum designs. For Korean organizations, the practical takeaway is to build systems flexible enough to run both national and international algorithms. That flexibility lets them align with domestic policy while keeping the interoperability their global operations require.
