KT to apply post-quantum cryptography security to defense systems

KT said on May 19 it will apply post-quantum cryptography to key South Korean defense systems through a 2026 pilot programme led by the Korea Internet & Security Agency with the Ministry of Science and ICT. The project aims to address security threats from advances in quantum computing and to apply and verify cryptography resistant to future quantum attacks on national core infrastructure. KT will run demonstrations with the defense ministry and the Army Information and Communications School.
