Perancangan Perangkat Lunak Filing System Dengan Memanfaatkan Kriptografi Hill Cipher Modifikasi

Abstract

Filing system software is a system that functions in archiving documents by digitizing so that it can facilitate users in searching documents and soft copies of the document can be used instead of the original document if the hard copy document is damaged or lost. This filing system software uses modified 2x3 hill cipher cryptography as security in archiving the document. The hill cipher cryptography was chosen because the encryption and decryption process uses matrix multiplication so that it is suitable for making keys with the debtor account number, and the hill cipher algorithm is modified to 2x3 thus strengthening its security. The results of this filing system software can store various documents with PNG image format and given the key by applying modified 2x3 hill cipher cryptography as security. This software can use LAN (Local Area Network) and office wifi as connections so as to facilitate connection between devices such as laptops and PCs. The conclusion of the results of this study is that this filing system software system can facilitate the credit unit in finding debtor documents can also be used as a backup if the original document of the hard copy of the debtor is damaged or lost so that it can be replaced again with the printed soft copy of the document in the filing system and the filing system implements the provision of keys with a modified 2x3 hill cipher algorithm in the document so that it can provide security if there are users other than the credit unit in accessing it
