Implementasi Hill Cipher Dan End Of File Untuk Pengamanan Pesan Rahasia Pada Citra
Along with the changing times and technological advances that are increasing rapidly, there is many new techniques are used to retrieve data, with the existence of these new techniques, it is also feared that the data taken will be misused by irresponsible parties, of course this can threaten confidential data or messages. Because of this, many developments have been carried out in the security sector so that several techniques have been formed to secure confidential data or messages, like kriptografi and steganografi technique. In this study two safety techniques are used namely Hill Cipher for kriptografi and End of File for steganografi, thus making message security presentations larger and not easily solved by unauthorized parties. The security of messages to images using the Hill Cipher and End of File methods has been successfully implemented to make secret messages more secure.
