Abstract
Cryptography is the science that concern of protecting data by transforming its comprehensible form into incomprehensible one. This study aims to compare between Advanced Encryption Standard (AES) and Rivest-Shamir-Adleman (RSA) encryption algorithms in image encryption using MATLAB. The comparison is done in the terms of testing image encryption quality for each algorithm. In addition, analyzing the histogram and correlation results. The results showed that AES algorithm has a better image encryption quality with a more convergent columns in the histogram. Moreover, AES algorithm correlation coefficient tends to be closer to the zero, thus a stronger correlation. Generally, the outcomes of this study showed that the AES algorithm is better than RSA algorithm in image encryption <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> .
