Abstract

Electronic seal is an important technology in nuclear disarmament verification, which is also widely used in nuclear safeguards, nuclear nonproliferation and other fields. This paper proposes a low vulnerability electronic fiber optic seal scheme according to the requirements of performance and low vulnerability for the seal. The seal system mainly consists of two major components, including the main control circuit and the secondary control circuit. The main control circuit includes the main microcontroller unit, the optical measuring unit, the temperature measuring unit, the switch measuring unit, the acceleration measuring unit and a data storage unit, mainly to complete multiple tamper indicating. In the main control circuit, the main microcontroller unit is the core of the system, mainly to implement the timing trigger, the timing adjustment, system fault diagnosis, fiber-optic monitoring, temperature monitoring, switch module monitoring, acceleration monitoring, and so on. The secondary control circuit includes a USB microcontroller unit and the encryption chip, mainly to complete data encryption and authentication. In the secondary control circuit, the USB microcontroller is mainly to implement the communication with external verification PC, legitimate users identification, encrypted-data transmission, starting/stopping the seal, clock synchronization calibration, and so on. In this way, the designed electronic fiber optic seal has been provided with multiple anti-tampering capabilities and lower vulnerability.
