Abstract

AbstractThere 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.Keyword: Steganography, Criptography, Prototype.AbstrakAda 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.Kata kunci: Steganografi, kriptografi, Prototipe

Abstract

The need for the availability of information is currently very high, especially in the conditions of the COVID-19 pandemic, all organizational activities are carried out online. Human dependence on the role of information technology is increasing and this has consequences for long distance communication between devices, which requires users to be authenticated for access rights granted by the system. The problem that arises is the security of data travel during the authentication process, where there is the possibility of leaking account information. This is because communication is done on a public network while accessing resources that require privacy. Therefore we need a network connection that is safe and efficient. Virtual Private Network (VPN) is a network communication technology that allows you to connect to public networks safely and quickly. The VPN used in the solution to this problem is Wireguard. Wireguard is a VPN protocol built with advanced cryptography and makes it extremely fast and secure. The method used by the author in developing this system is PPDIOO which consists of, Prepare, Plan, Design, Implement, Operate, and Optimize. And also some supporting tools for the development of the system Unified Modeling Language. By using Wireguard VPN, the expected result is the security of the data sent to be more secure and can connect two remote networks privately using the public internet.Keywords : VPN, Wireguard, Mikrotik
