IMPLEMENTASI KRIPTOGRAFI PADA KEAMANAN DATA MENGGUNAKAN ALGORITMA ADVANCE ENCRYPTION STANDARD (AES)

Abstract

Security is an important part of the data framework, this viewpoint is often prominent enough to be noticed by database owners and administrators. In this case, our team develops an information system that uses cryptography to secure documents. Encryption and description are two important concepts in the field of cryptography. To keep the stored data from being blocked for unauthorized parties, data security is needed. In order not to intercept or steal documents that contain important data for clients and to maintain this trust, calculations are needed that can protect records, namely High Level Standard Encryption Computation (AES). The purpose of this study is to use the AES algorithm to ensure data security. The results of this study obtained that files or documents that go through the encryption process, the contents of the file will turn into symbols that cannot be read just like that. Then, when the encryption results go through the decryption process by entering the key used in the encryption process, the contents of the file will return to normal.
