Aplikasi Pengamanan Informasi Menggunakan Metode Least Significant Bit (Lsb) dan Algoritma Kriptografi Advanced Encryption Standard (AES)

Abstract

<jats:p>&lt;p align="center"&gt;&lt;strong&gt;&lt;em&gt;Abstract&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype. The results of this study are all aspects of data security can be achieved, including when passing through the process of sending data through media such as the internet.&lt;/em&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;&lt;em&gt;Keyword: &lt;/em&gt;&lt;/strong&gt;&lt;em&gt;Steganography, Criptography, Prototype.&lt;/em&gt;&lt;/p&gt;&lt;p align="center"&gt;&lt;strong&gt;&lt;em&gt;Abstrak&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;em&gt;Ada beberapa aspek keamanan data yang harus dijaga, seperti: otentikasi, integritas, non repudiation, otoritas, kerahasiaan, privasi, dan kontrol akses. Salah satu bagian yang rentan dari keamanan data adalah ketika mengirim data ke tujuan. Pada saat pengiriman, penyadapan data dapat terjadi, sehingga orang yang tidak berhak mendapatkan informasi tersebut dapat mengetahuinya. Oleh karena itu, suatu informasi perlu diamankan sehingga hanya orang yang memiliki hak akses yang dapat mengetahui atau mendapatkan informasi tersebut. Dan untuk menjaga kerahasiaan informasi, salah satu caranya adalah dengan memasukkan data ke objek lain, sehingga orang lain tidak menyadari jika objek tersebut berisi data atau informasi penting. Metode persembunyian ini juga dikenal sebagai steganografi, dan kriptografi ditambahkan untuk memperkuat keamanan data, yaitu ilmu dan seni untuk menjaga kerahasiaan pesan dengan menyandikannya dalam bentuk yang tidak dapat dipahami. Metode yang digunakan dalam steganografi adalah Least Significant Bit (LSB), algoritma yang digunakan dalam kriptografi adalah Advanced Encryption Standard (AES), dan metode pengembangan perangkat lunak yang digunakan adalah prototipe. Hasil dari penelitian ini adalah semua aspek keamanan data dapat dicapai, termasuk ketika melewati proses pengiriman data melalui media seperti internet.&lt;/em&gt;&lt;/p&gt;&lt;strong&gt;&lt;em&gt;Kata kunci:&lt;/em&gt;&lt;/strong&gt;&lt;em&gt; Steganografi, kriptografi, Prototipe&lt;/em&gt;</jats:p>

Comparative Analysis of Performance Between Ecmp and NTH Methods in Implementation of Microtic-Based Dual Link Load Balancing Techniques

“…The method used in this study uses a qualitative method where the researcher is the main tool in data collection [14]. The data collection that the author does is by looking for reference sources related to the research topic, both from scientific journals and from books.…”

Implementation and Use of Base64 Algorithm in Video File Security

“…The encryption process is carried out using an algorithm with several parameters. (Novianto & Setiawan, 2019) Base64 transformation is one of the algorithms for encoding and decoding a data into ASCII format, which is based on the base number 64 or can be said to be one of the methods used to encode (encoding) binary data. according to (Novianto & Setiawan, 2019) quoted by Gunadhi, et al (Novianto & Setiawan, 2019)Base64 transformation is one of the algorithms for encoding and decoding data into ASCII format, which is based on the base 64 number or be said to be one of the methods used to encode binary data.…”

Base64 transformation cryptography is widely used in the Internet world as a media data format for sending data, this use is because the results of the base64 encode are plaintext, so this data will be much easier to send, compared to binary data formats.…”

Steganography Formation by utilizing Enhanced Least Significant Bit Algorithm

“…Whereas, if the LSB bit is 0, then all bits in the byte are replaced with 0 bits so that the byte value is 00000000 (binary) or 0 (decimal). After the filtering process, the image in the image not inserted by the message will approach the original image [10]. While the part of the image containing the secret message will become corrupted after filtering.…”
