Lightweight cipher fails NIST’s quantum test
A paper calculation finds a small-device cipher falls short of NIST’s quantum security bar. It shows a design gap, not a break of any deployed system.

Quantum attacks on Chaskey are far off
Breaking Chaskey or PRINCE takes 2⁶⁵ operations, against 2³¹ for RSA-2048. Systems with long-term secrets should plan migration now.

Cracking RSA with fewer qubits takes months
Factoring RSA-2048 would take 177 days on 13,436 qubits plus a memory not yet built. Migration deadlines do not depend on it.

Cracking Bitcoin needs 317 million qubits
Breaking Bitcoin’s key encryption within one hour takes 317 million physical qubits in this estimate. Nothing to act on yet.
