Method of remote sensing image detail encryption based on symmetry algorithm

The details of remote sensing digital image contain some sensitive information, so the encryption process is prone to the defects of low key sensitivity and poor security. In view of the above problems, this paper studies the method of remote sensing image detail encryption based on symmetry algorithm. Enlarge the remote sensing image to obtain high resolution remote sensing image. The remote sensing image is processed to remove the thin cloud and fog, and the details of the remote sensing image are extracted. The encryption key of remote sensing image details is designed, and the encryption of remote sensing image details is realized by symmetric algorithm. Experimental results show that the key sensitivity and encryption security are improved.
