“…Setiap karakter dalam satu blok akan saling mempengaruhi karakter lainnya dalam proses enkripsi dan dekripsinya, sehingga karakter yang sama tidak dipetakan menjadi karakter yang sama pula. Menurut penelitian yang dilakukan oleh [15], penggunaan metode hill cipher termasuk algoritma kriptografi klasik yang sangat sulit dipecahkan oleh kriptanalis apabila dilakukan hanya dengan mengetahui berkas ciphertext saja. Karena Hill Cipher tidak mengganti setiap abjad yang sama pada plaintext dengan abjad lainnya yang sama pada ciphertext karena menggunakan perkalian matriks berukuran m x m sebagai kunci untuk melakukan enkripsi dan dekripsi, karena dasar yg digunakan matriks Hill Cipher antara lain adalah perkalian antara matriks dan melakukan invers pada matriks.…”

“…Algoritma Hill Cipher menggunakan matriks berukuran m x m sebagai kunci untuk enkripsi dan dekripsi. Block cipher tipikal ini yang bergantung terutama pada invers aritmatika modular dari matriks kunci sangat kuat terhadap serangan brute force, memiliki ketahanan terhadap analisis frekuensi, kecepatan tinggi dan throughput tinggi, dan sulit dipecahkan dengan ciphertext-hanya menyerang, tetapi mudah dipatahkan dengan serangan plaintext yang diketahui, dengan asumsi musuh telah memperoleh beberapa pasangan plaintext dan ciphertext [15]. Kemunduran lain adalah bahwa matriks kunci yang dapat dibalik diperlukan untuk dekripsi, jika matriks kunci enkripsi tidak dipilih dengan benar, pembangkitan matriks kunci dekripsi yaitu kebalikan dari matriks enkripsi tidak dimungkinkan [16].…”

Keamanan data dalam sistem merupakan problem yang hingga saat ini membuat peneliti terus mengembangkan keilmuan. Kriptografi sebagai salah satu teknik keamanan data, khususnya pada data teks melalui implementasi kriptografi klasik. Pada penelitian ini telah diimplementasikan kombinasi vigenere dan hill cipher. Kedua algoritma merupakan algoritma yang mudah dalam implementasi, namun masing-masing memiliki kekurangan. Vigenere mudah di brute force, sedangkan hill cipher pada proses dekripsi harus menggunakan kunci yang dapat dibalik sehingga tidak semua kunci cocok untuk digunakan. Kombinasi Vigenere dan hill cipher telah diimplementasikan dan di uji coba menggunakan black box testing serta perhitungan Avalanche Effect. Pengujian menggunakan Avalanche Effect menghasilkan nilai rata-rata 52,46%.

A new encryption technique for multicolor images is outlined in this study. After vectorization of the clear image, an initialization value will be calculated. This value, allows changing only the first pixel. This pixel will start the encryption process. In parallel, in a first step, we will make a confusion by chaotic vectors entirely controlled by another chaotic vector. In a second step, three chaotic substitution matrices of size (256, 256) will be generated. The passage of each pixel through these matrices will also be controlled by another chaotic vector. Finally, a strong link will be set up between the new pixel state and the previous ones to set up better diffusion/confusion. This step increases the avalanche effect. Testing performed through our algorithm on standard images shows the durability of our system.

“…Furthermore, research conducted by Kalaichelvi (Kalaichelvi et al, 2017) also proposed a new variation of the Hill cipher encryption algorithm to provide data security by using Radix 64 to overcome the weakness when encrypting identical plaintext blocks to identical ciphertext blocks. Meanwhile, (Hraoui et al, 2019) proposed an improvement to the Hill cipher algorithm in the case of Affine transformation. In this study, the authors propose a cryptographic algorithm that combines the Hill cipher method with the Rubik's cube.…”

Message security is must be managed seriously. Therefore, to maintain the confidentiality of any message, cryptography is needed. Cryptography is a science that uses mathematics to encrypt and decrypt messages. Cryptography is used as a tool to protect messages, for example, national secrets and strategies.Â The method of this research is qualitative research with a literature review. This research implements a hybrid cryptographic algorithm by combining Hill cipher and 3x3x3 Rubik's cube methods with Python software simulation.
