Abstract

Sending data and messages through various media is a common activity. However, the leak and piracy of information can be a high risk. To protect the security of messages, this study uses the combination of AES cryptographic and End of File steganography methods. This study focuses on embedding a secret message in the form of text into an image in PNG format using End of File steganography method. Before embedding, the message is encrypted using AES cryptography method. In this study, 6 images with different resolutions are tested and in each image 15 words are embedded with ASCII characters encrypted. The quality of the embedded image is measured by PSNR and SSIM values. Based on the PSNR and SSIM values of the tested images, it can be concluded that the end of file steganography technique is considered suitable for embedding secret messages. Based on the time required for the embedding process, the average time is between 0.5 and 0.7 seconds and the average computation time resulting from the testing process is relatively stable at 0.59 seconds. Therefore, it can be concluded that the time required for embedding the message tends to be short and stable. Keywords : Steganography, Cryptography, End of File, AES, PSNR, SSIM
