German and US scientists think they might have the answer, using a technique much like the PUFs – physically uncloneable functions – used in add unpredictable unique identity numbers to ICs.
“The technology combines cyber-physical security assessments, previously only possible on data and security chips, with cross-system physics in a completely new way,” said Professor Christian Zenger of Ruhr University Bochum (RUB).
The new idea is to set up a 3 to 9GHz RF field in the vicinity of the warhead and monitor that remotely for changes.
