Abstract

An image is a representasion of an object that has visual information. In transferring and receiving image, the information contained in the image can be known by unwanted people. Cryptography is used to secure data. The image has some extensions like .bmp and .png. .bmp and .png extension have large sizes of images. This study uses AES cryptography algorithm is used to encrypt and decrypt .bmp and .png file. Histogram analysis results of the .bmp image encryption show a significant difference between the plain image and the encrypted image for each of the red, green, and blue channels. Histogram analysis on .png image also show significant difference beetwen the plain image and the encrypted image, so the information in the image is difficult to know. Encrypted image have a larger size than the plain image, both in .bmp and .png image. From the histogram analysis and encryption results, can be concluded that the AES algorithm is good for .bmp and .png image encryption and decryption. Keywords: Cryptography, Encryption, Decryption, Advanced Encryption Standard
