WHAT HAPPENED

Research claims that a post-quantum key exchange can be broken in 1,700 queries, while a hardened variant falls in 180 queries. A separate study reports lower attack costs against elliptic-curve encryption.

SO WHAT?

If validated and practical, these findings could weaken widely used encryption and accelerate the need for cryptographic migration.

SCORE CONTEXT

Why 58 is a meaningful score

5841–60

A score of 58 sits in DoomRadar's 41–60 band, which represents meaningful regional, economic or public impact. The score estimates potential severity and wider impact; it is not a probability or a forecast of losses.
