Abstract

Verification inspections that support nuclear weapon arms control treaties can require photographs to be taken as part of the inspection evidence. In a nuclear weapon facility, the host would generally want to review images before they are released to the inspector to prevent the accidental release of sensitive information. Currently, giving the host sole custody of the images for review severely impacts the confidence of the inspector that the images are genuine and unmodified. This paper outlines how simple cryptographic methods can be employed to allow the host sole custody for review while maintaining the inspector’s confidence in the veracity of the images. The concept is then expanded to propose and illustrate the capability for the host to redact a portion of an image while still allowing the inspector to verify that the remainder of the image is genuine. The ability to allow a host to have sole custody of images for review, and even redaction, without affecting inspector confidence in the veracity of the images they receive would contribute to improved processes for nuclear weapon verification in future arms control treaties.

摘要

支持核武器军备控制条约的核查检查可能需要拍摄照片作为检查证据的一部分。在核武器设施中，主机通常希望在将图像发布给检查员之前对其进行审查，以防止敏感信息的意外泄露。目前，让主机单独保管图像以供审查严重影响检查员对图像真实和未经修改的信心。本文概述了如何使用简单的加密方法允许主机单独保管进行审查，同时保持检查员对图像真实性的信心。然后扩展该概念以提议并说明主机编辑图像的一部分同时仍允许检查员验证图像的其余部分是真实的的能力。在不影响检查员对他们收到的图像真实性的信心的情况下，允许东道主单独保管图像以供审查甚至编辑的能力将有助于改进未来军备控制条约中核武器核查的过程。
