Building a Dedicated Information Barrier System for Warhead and Sensitive Item Verification

This paper documents the development of a dedicated information barrier system for warhead and sensitive item verification. The system we describe includes software and hardware information barriers used in conjunction with suitable procedures (or protocols) to achieve a high quality verification while minimizing intrusiveness and preventing transfer of sensitive data to inspectors. The system we describe has been referred to as a CIVET -- Controlled Intrusiveness Verification Technology and has been implemented to verify warheads and warhead components during various exercises and demonstrations.
