Iso/iec: 24759:2025

Now, a state actor had weaponized that drift.

Dr. Aliya Voss, the GCA’s chief validation architect, stared at the logs. The modules in question were certified against the 2022 version of ISO/IEC 24759. At the time, they were gold standard. But the new 2025 revision—published just six months ago—had warned of exactly this vulnerability: a class of side-channel timing attacks that exploited speculative execution in post-quantum key encapsulation mechanisms. iso/iec 24759:2025

And in quiet labs, engineers would tap the cover of the purple-bound standard and say: “This one? This one was written in blood.” If you’d like, I can also summarize the between the 2017 and 2025 versions of ISO/IEC 24759 (based on known trends in cryptographic standards). Just let me know. Now, a state actor had weaponized that drift

Aliya grabbed a red pen and flipped to the back of the 24759:2025 standard—the section no one reads: Informative Annex M – Case Studies of Test Failures . She wrote in the margin: The modules in question were certified against the

The breached modules? They used an older RNG test. They’d passed 24759:2017. They failed 24759:2025’s extended entropy continuity test—a test that simulated 10⁹ power cycles and looked for drift in noise sources.

“Add new case: Kalshira. 2.2B records. Cause: module vendor skipped §8.47 to save 3% on validation cost. Standard was sufficient. Implementation was not.”
