Cryptographic algorithm should be designed in such a way that on the one hand can be used by legitimate users, but on the other hand is a difficult problem to the attacker to solve. An important criterion for a good cryptographic algorithm is that it must be practically efficient for legitimate users. An algorithm is also generally expected to be effective which means that all operations must be done in a fairly basic algorithm that can in principle be done right and in a limited length of time. Digital images can be quickly copied, transferred and duplicated with no loss of information or image quality. Visual inspection is not enough to determine the quality of the encrypted image. In this study conducted a comparison of the digital image using the Rijndael algorithm and Camellia algorithm. Comparisons were made on three digital image format .bmp, .jpg, .png with size 32x32 pixels test images. This study uses parameters such as Big O, Avalanche Effect, maximum deviation, correlation coefficient, irregular deviation and image PSNR to determine the efficiency, effectiveness, quality of Rijndael algorithm with Camellia algorithm at digital image. Based on the results of tests performed some conclusions are obtained, Rijndael algorithm is more efficient than the Camellia algorithm, Camellia algorithm is more effective than the Rijndael algorithm and in terms of the quality Rijndael algorithm is superior compared to Camellia algorithm.
