Because it makes the data or files being vulnerable to take or even locations by parties who have no right to know the information, especially on file image. Cryptography is a technique that can be secured data or file on of messages by means manipulate data or such file into something that does not mean. At this time, there were various encryption algorithms in the image file, but this time chose RSA and Naïve RSA in the security of the image file. This RSA algorithm is classified as a safe algorithm but takes a long time in the encryption and decryption process. Because RSA is more combined with other algorithms (Super Encryption), RSA reliability has not been completed if the encryption and decryption process in the image file uses only one RSA algorithm. The study produces time graphs and images in the Naïve RSA Algorithm and Rprime RSA which produce pixels that are directly proportional to time. If the pixel size of the image is large, the greater the time needed for the image encryption process.} }
