    Abstract: This study presents a new method of encrypting color digital images using magic square. The
proposed method generates an encryption key by using magic square and encrypts images using the generated
key. The encryption method changes the RGB (Red, Green and Blue) values of each pixel of the plain-text image
using the generated key. The process starts by splitting the plain-text image into three arrays that hold RGB
values. After encrypting each segment of 256 pixels of the RGB arrays, the encrypting key is permuted by using
magic square. At the end, the encrypted image is generated by merging all three encrypted RGB arrays together.
For the decryption of the cipher-image, the same process of encryption used but with the encrypted images as
the input.
