Description
Technical field:
the invention relates to the field of encrypted radiation measurement, in particular to a arms control treaty checking system based on liquid mask random coding.
The background technology is as follows:
Previous studies have shown that the actions based on destroying the associated hardware of the nuclear weapon, such as destroying launched missiles, submarines, etc., are not sufficient to eliminate the threat posed by them. The difficulty related to the information technology of the authentication nuclear weapon is that: it is necessary to verify the identity of the checked treaty item on the basis of protecting its sensitive information. The physical encryption mode can complete the detection task without measuring sensitive information, so that the security is higher, and the method is favored by researchers compared with single back-end algorithm encryption. The invention provides a arms control treaty checking system based on liquid mask random coding, which can finish identity authentication of a tested item with higher resolution on the basis of encrypting sensitive information of the tested item in the physical field.
The invention comprises the following steps:
In order to solve the technical problems involved in the nuclear weapon identity authentication method, the invention provides a arms control treaty checking system based on liquid mask random coding, which consists of a detection neutron source, a rotating mask and a neutron detector array. The neutron source and the neutron detector array for detecting the neutrons in the invention can acquire neutron photographing information of the measured treaty project, including transmission, scattering, absorption and other information of neutrons, and can reflect the material and internal structure information of the treaty project to a certain extent. The spin mask is composed of a cross-linked polyethylene foam having higher strength, abrasion resistance and chemical resistance than general polyethylene, and heavy water, so that the structure thereof is more stable in a radiation field. The cross-linked polyethylene foam has irregular formic nest shape, and has long and narrow gaps, and is favorable to heavy water flow in the foam, so that the randomness of the checking system is increased, and the outer part of the checking system is encapsulated by using polyethylene materials. After injecting heavy water into the crosslinked polyethylene, which is approximately equal to three-fourths of its remaining space volume, the heavy water can randomly flow in the "formicary" gap with rotation of the liquid mask under the action of gravity, randomly distorting the energy and exit direction of neutrons.
Under the same experimental condition, the inspection system provided by the invention is utilized to obtain the neutron photographing sequence information of the reference item, and the neutron photographing sequence information is used as a standard answer for comparing the neutron photographing sequence information of the treaty item so as to confirm whether the two photographing information come from the tested item of the same category. If the two information confirms that the items come from the same category, the treaty item is considered to pass detection, the identity information is consistent with the prior statement, otherwise, the treaty item is considered to be a cheating item. Based on the unordered flow of heavy water in the crosslinked polyethylene foam and the shielding property of the heavy water to neutrons, the rotary mask in the checking system increases the safety in the checking process to a certain extent, and can meet the checking requirement of arms control treaty items.
Based on arms control treaty checking system provided by the invention, the checking party firstly needs to obtain a reference sample, namely a real nuclear warhead, for example, the checking party can randomly select one as the reference sample from the nuclear weapons already deployed by the checked party. From the validation of the reference sample to the completion of the measurement, the sample requires a check of the mutual supervision of both parties throughout to prevent tampering. Subsequently, the two parties are checked to determine experimental conditions of irradiation detection, such as irradiation time, rotation sequence of the mask (one rotation sequence contains one hundred rotation parameters, each parameter can determine one neutron photographic information, one hundred parameters can determine one neutron photographic sequence information for confirming identity information), and relative positions of the components, so as to increase mutual credibility of the two parties. Under the same experimental condition, the encrypted neutron photographic sequence information of the reference item and the treaty checking item is respectively obtained, and a template comparison method is combined to calculate a difference metric value C of the treaty checking item and the reference item, wherein the difference metric value C is defined as follows:
In the formula (1), DK is the difference value of single neutron photo information under different rotation parameters of the same rotation sequence, C is the total difference value of two items under the same rotation sequence, D is defined as shown in the formula (2), wherein R is the two-dimensional data of single photo information in the neutron photo sequence information of a reference sample, V is the two-dimensional data of single photo information in the neutron photo sequence information of a treaty checking item, and m and n are the detector array dimensions in a checking device.
Under the same experimental condition, multiple times of measurement are carried out on the reference sample, a plurality of encrypted neutron photographic sequence information related to the reference sample are obtained, the encrypted neutron photographic sequence information related to the reference sample is matched with each other, the difference metric value is calculated by using a formula (1) and a formula (2), the average value T is taken as a judgment threshold value, and if the difference metric value is smaller than the T value, the treaty checking item is considered to be consistent with the prior statement item, otherwise, the identity of the item is considered to be suspicious, and further checking is needed to be carried out by combining other methods.
