“…Attackers systematically check all possible passwords and passphrases until they find the correct one [22]. Not only password guessing, if someone tries to guess the sinovi app URL, it can also be considered as brute force [23], [24]. So in this research will use several images as a sample encryption test.…”

In this era of increasingly rapid technology, the development of information systems is also growing rapidly, because information systems provide what users need. Information is a very valuable thing. When information or data falls into irresponsible hands, it will bring disaster to the owner, and there have been many cases of data leaks in the past that have harmed several parties. There are various ways to protect data or information. Therefore, data security techniques are needed, the message security process is very diverse, including using cryptography. Cryptography aims to scramble messages so that they are difficult to read by unauthorized parties. In this study, we will use the AES 256 encryption method with the waterfall research method to secure KTP images on the Sinovi application, Sinovi is a copyright registration application at the Telkom Institute of Technology Purwokerto. The results of this study are the AES method will convert data or information in the form of plain text into cipher-text then stored in a file to replace the image file so that in this way the image cannot be viewed directly because it must pass the decryption technique first and the research data will be presented. in a table of blackbox testing. It is hoped that a security system like this can protect data from unauthorized parties and further research is expected to have research that tests AES 256 with different methods. https://github.com/teguh02/T-Encryption

“…Rentang nilai ini dapat diperluas menjadi 128 karakter untuk mengakomodasi ASCII standar atau menjadi 256 karakter agar dapat mengakomodasi seluruh nilai ASCII standar dan ASCII extended [5], [6]. Rentang nilai hingga 256 ini juga berguna untuk mengakomodasi nilai piksel pada citra [7], [8].…”

“…Perluasan rentang karakter dari 26 menjadi 128 dalam [5] dan 256 dalam [6] memberikan hasil berupa susunan acak dari karakter ASCII. Perluasan ini juga memungkinkan VC digunakan untuk melakukan engkipsi pada citra [7], [8]. Namun, implementasi VC pada citra masih memerlukan optimasi lebih lanjut karena VC hanya memberi perubahan pada warna citra.…”

“…Peningkatan entropi tertinggi adalah sebesar 34,8 % pada teks berulang dibandingkan dengan teks berbahasa Indonesia dan teks berbahasa Inggris masing-masing 6,1 Peningkatan keacakan ini menunjukkan kecenderungan yang sama dengan penggunaan bit circular shift seperti dalam [7] dan double transposition dan OTP dalam [6] dalam meningkatkan hasil enkripsi VC. Peningkatan keacakan pada teks berbahasa Indonesia dan teks berbahasa Inggris yang sejak awal memang sudah memiliki keacakan yang tinggi, relatif kecil dibandingkan dengan yang terjadi pada teks berulang yang memiliki tingkat keacakan yang jauh lebih rendah.…”

Information that can be in the form of text, image, audio, and video, is a valuable asset that needs to be secured from unauthorized parties. This research aims to study the implementation of Vigenere cipher 128 (VC-128) and square rotation to secure text information. The square rotation is applied to increase the security of the encryption results obtained from VC-128. The randomness of the rotation results was measured using Shannon entropy based on the distance between characters, and the Avalanche Effect measured changes in the encryption results compared to the original text. The square rotation can increase the randomness of the VC-128 encryption results, as indicated by an increase in entropy values. The highest increase in entropy of 34.8 % occurs in repetitive texts with the square size that produces optimal entropy was a 9x9 medium-size square. The Avalanche effect for each test data shows inconsistent results ranging from 44.5 % to 49 %.
