Abstract:Industrial Internet-of-Things (IoT) has recently emerged and is undergoing rapid development, and image data collected through IoT nodes or terminals is related to personal information. For the protection of image data in IoT, especially in smart grid, we propose a new lightweight image encryption and collection scheme. First of all, a random permutation matrix was used to disturb the association between original and encrypted images. Secondly, to further strengthen the encryption, we select only a portion of … Show more
