Abstract

ABSTRAKData sangatlah berharga bagi semua pengguna komputer, belakangan ini kriptografi menjadi metode yang digunakan dalam mengamankan data. Kriptografi adalah ilmu yang mempelajari teknik-teknik matematika dalam mengamankan suatu informasi atau pesan asli (Plainteks) menjadi sebuah teks tersembunyi (Chiperteks) dan kemudian di ubah menjadi pesan asli kembali. Kriptografi mempunyai tiga unsur penting yaitu pembangkitan kunci, enkripsi dan deskipsi. Dalam kriptografi di kenal algoritma block chiper yang didalamnya terdapat AES (Anvanced Encyption Standard) merupakan bagian dari Modern Symmetric Key Cipher, algoritma ini menggunakan kunci yang sama pada saat proses enkripsi dan deskripsi sehingga data yang kita miliki akan sulit dimengerti maknanya. Teknik algoritma tersebut digunakan untuk mengkonversi data dalam bentuk kode-kode tertentu, untuk tujuan agar informasi yang tersimpan tidak bisa di baca siapa pun kecuali orang-orang yang berhak. Oleh karena itu, sistem keamanan data sangat di perlukan untuk menjaga kerahasian informasi agar tetap terjaga. ABSTRACTData is a valueable  for all computer users, cryptography is the one of  method used to securing data. Cryptography is the study of mathematical techniques in securing an information or original message (Plainteks) into a hidden text (Chiperteks) and then converted into the original message again. Cryptography has three important elements, first is key generation, second is encryption and latetly is description. In cryptography known as cipher block algorithms in which AES (Advanced Encyption Standard) is part of Modern Symmetric Key Cipher, this algorithm uses the same key during the encryption and description process so that the data we have will be difficult to understand. The algorithm technique is used to convert data in the form of certain codes, so that the information stored cannot be read by anyone except those who are entitled. Therefore, the data security system is very necessary to maintain the confidentiality of information.

Abstract

Nowadays, technological advances have made it increasingly easy to obtain information, especially image data (digital images). Digital image is an interesting thing to look for information. So that misuse of data can be done for personal or public interests. Misuse of data can be avoided by adding data security systems. Cryptography is the science of securing data. Cryptography can be done using the AES (Advanced Encryption Standard) algorithm, which is an algorithm that utilizes symmetric keys. Testing is done by entering the same key in the encryption and decryption process. Encryption is the process of encoding plaintext (original text) into ciphertext (text that has been encoded). While decryption is the process of recovering the plaintext from the ciphertext. Therefore, data security is an important thing to do. This study aims to find out how encryption and decryption on the AES algorithm can be used to secure digital data. The results of this study indicate that the encryption and decryption process on the AES algorithm was successfully carried out so that it can be used to secure data on digital images.
