Abstract

Dokumen mungkin bersifat rahasia dan penting bagi entitas tertentu, sehingga diperlukan mekanisme keamanan khusus. Encryption with Covertext and Reordering (ECR) merupakan  model keamanan dokumen berbasis teks. ECR memanfaatkan kunci random untuk memilih ciphertext. Kunci random dalam ECR diproses secara manual. Penelitian ini bertujuan untuk meningkatkan tingkat keamanan dokumen dengan menggunakan model enkripsi ECR. Tabel permutasi kunci acak yang diusulkan dalam  model enkripsi ECR berubah. Nilai random diseleksi dengan otomatis menggunakan fungsi random pada tabel permutasi. Dalam penelitian ini salah satu ukuran yang digunakan adalah entropi, yaitu nilai tingkat keamanan dokumen terenkripsi. Hasil pengujian menunjukkan bahwa pengintegrasian tabel permutasi  kunci acak memberikan nilai entropi yang lebih baik, yang menyiratkan tingkat keamanan yang lebih baik. Menggunakan tabel permutasi kunci acak juga memudahkan penggunaan ECR untuk mengamankan dokumen.

Abstract

Information systems cannot be separated from a database as the main database. As time goes by, the amount of data processed by information systems increases significantly. Currently, databases are not only stored in one storage media location, but can also be stored in different locations and locations. This is also supported by advances in network technology, both hardware and supporting software. The distributed database system model provides significant support for processing data stored in different locations. Many information system implementations use the concept of a distributed database system. The aim of this research is to study the development of database system implementation using distributed database system technology. This research uses a systematic literature observation approach. The results obtained are that the concept of a distributed database system is still used today to support information system governance that produces information tailored to user objectives. Systems created using development techniques based on the distributed database concept have advantages in several aspects of development.
