论文摘要
本文的目的是评估视觉变压器对拼图拼图求解器攻击的基于块的图像加密的安全性。视觉变压器是基于变压器体系结构的图像分类的模型，是通过将图像分为正方形贴片网格来进行的。通过应用基于块的图像加密（例如块拼凑而旋转到图像斑块），已经提出了视觉变压器的某些加密方案。另一方面，视觉变压器的加密方案的安全性从未评估过。在本文中，拼图拼图求解器的攻击被用来评估被拼图拼图的片段，以评估加密图像的安全性。在实验中，调整图像的大小并分为贴片以应用基于块的基于块的图像加密，然后评估了视觉变压器对拼图拼图求解器攻击的加密图像的安全性。
The aim of this paper is to evaluate the security of a block-based image encryption for the vision transformer against jigsaw puzzle solver attacks. The vision transformer, a model for image classification based on the transformer architecture, is carried out by dividing an image into a grid of square patches. Some encryption schemes for the vision transformer have been proposed by applying block-based image encryption such as block scrambling and rotating to patches of the image. On the other hand, the security of encryption scheme for the vision transformer has never evaluated. In this paper, jigsaw puzzle solver attacks are utilized to evaluate the security of encrypted images by regarding the divided patches as pieces of a jigsaw puzzle. In experiments, an image is resized and divided into patches to apply block scrambling-based image encryption, and then the security of encrypted images for the vision transformer against jigsaw puzzle solver attacks is evaluated.
