As the technology and information develops, the greater the risk or the crime occurs. One of the most common crimes is counterfeiting and hijacking the information sent. Therefore, to maintain the confidentiality of such information requires a technology that can conceal information transmitted, such as cryptography. Based on the key used, the cryptographic algorithm consists of symmetric cryptography and asymmetric cryptography. One example of a symmetric key algorithm is the Advanced Encrypted Standard algorithm and the asymmetric key is Rivest-Shamir-Adleman. In this final project, built a digital image encryption and decryption system to analyze the performance of the two algorithms. Image type used is RGB image with different size. The results obtained in this system is, AES algorithm produce better cipher image but this algorithm require longer processing time compared with RSA algorithm. The performance of both methods is calculated by finding Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) values. From the average value of MSE and PSNR obtained, we found the perfect MSE and PSNR values on the RSA algorithm with MSE = 0 and PSNR = inf.
