Gaussian noise attack analysis diagram. Image (a) is color house image, (b) is a result image of adding density 0.08 Gaussian noise to the encrypted image (a), (c) is a decryption image of (b), (d) is a result image of adding density 0.2 Gaussian noise to the encrypted image (a), and (e) is a decryption image of (d). Image (f) is color monkey image, (g) is a result image of adding density 0.08 Gaussian noise to (f), (h) is a decryption image of (g), (i) is a result image of adding density 0.2 Gaussian noise to (f), and (j) is a decryption image of (i). The image (k) is color map image, (l) is a result image of adding a density of 0.08 Gaussian noise to the encrypted image (k), (m) is a decryption image of (l), (n) is a result image of adding a density of 0.2 Gaussian noise to the encrypted image (k), and (o) is a decryption image of (n).
