A physically cryptographic hoteling observer for nuclear warhead verification

When verifying the authenticity for nuclear warheads dismantlement toward a treaty partner's obligation, arms verification technologies are critical since only disarmament treaties not sufficient to neutralize existential threat of weapons. In this work, we present method combining numerical observer model and physical encryption techniques. The performance is quantified by Monte Carlo simulations with several typical deception scenarios. Simulation results show can efficiently complete identification tasks in presence noise (<5 %) source-term variability, meanwhile exhibiting high security against brute-force attacks which reconstruct detection data exhaustive method.
