| Abstract: | This research discusses encryption and security description of files in images with hill cipher cryptography and steganogography using the lsb + 1 method, testing the results of cryptographic and stegano data security applications that are equipped with cryptography, then from the results the trial was done with the hill cipher method, by displaying data in the form of files that want to do the data security. The results of the DIPA trial with a file size of 17.2 MB after being encrypted into RNPF with a file size of 17.2 MB. |
| Description: | As time goes by, secrecy of messages for some people is very important in order to get data that is not at all other people know. Very sensitive secrecy about the illegal stealing of messages, triggering some people to convey the message's secrecy itself, in order to avoid threats from outsiders who want to forcibly take the contents of a message that some people think is very important. Today, there are many applications about maintaining the confidentiality of the message itself. Maintaining the confidentiality of messages has been going on for a long time. People often call it steganography, which is hiding messages on the media, such as pictures. For now, steganography has been applied to the digital world such as computers. Steganography is generally use to hide information in the image, where the information in the form of text is inserted into the bits making up the image. With this method the author tries to combine the steganography method with other methods. Cryptography itself is a science or art to maintain the security of a data. In the cryptographic world the same letter in the message has the same letter image as well. This has a high level of risk because it is easy to guess. To resolve this so the message must be encoded (encoding). The goal is to be safe from other people who want to take data contents illegally. Hill cipher is one of the classic cryptographic methods that is often applied, hill ciphers apply simteric keys that utilize the nxn matrix as the key. The hill cipher algorithm is manipulating words that use matrix operations in the form of inverse multiplication. Background retrieval regarding the hill cipher method and steganography itself is an application for safeguarding data that is wanted to be secured by an interested person. The hill cipher method itself is a classical cryptography or cryptography which uses the simteric key in its application, where this key is a matrix, which contains the key of the hill cipher method itself then the key that has been applied in the execution uses mod 26. This research also combines other methods namely lsb (significant bit list) where this method implements insertion of the lowest in-bit message in a digital image, where the insertion is entered by the compiler bit of the message that you want to enter. |
