The standardization enables broader, interoperable adoption across ISO's 177 member states. The algorithm, built on Professor Robert McEliece's 1978 cryptosystem using error-correcting codes, is recommended by national security agencies including Germany's BSI and its Dutch counterpart. Real-world deployments include quantum-safe VPNs tested by NATO and battlefield-ready drone communications with Czech defence manufacturer STV Group. The move comes amid growing urgency around Q-Day threats and Harvest Now, Decrypt Later (HNDL) attacks, with some experts estimating current encryption could be broken within three years. ## Full article daily.dev links to this article rather than hosting it.
