The condition of the world experiencing the COVID-19 pandemic has resulted in some daily activities limited by health protocols. The Indonesian government's policy in the academic field has forced STIE Mandala Jember, as one of the private universities, to implement online-based new student admissions. The registrant's identity must be kept confidential during the online-based new student registration process, so the running system needs an identity coding (encryption) process. Hill Cipher is a cryptographic algorithm that utilizes the multiplication of matrix inverse operations. In ordinary Hill Cipher, to encrypt the entire plaintext, a key is needed. In this paper, we will modify the Hill Cipher named Hill Cipher Chain. The process of chained Hill Cipher will encrypt and decrypt the primary key based on the previous character. Firstly, we will encrypt the primary key with the key from the next column of the database. In this case, we use the name column. The encryption result will be used as a key for the subsequent character encryption. Implementation of this method makes the difficulty level of decryption more complex than the ordinary Hill Cipher, which only uses one key for all so that the security of the data obtained is also getting better.

One of the essential instruments in the cyber era is data. Therefore, maintaining data security is an important thing to do. One way that can be done to maintain data security is through cryptography. In cryptography, two basic techniques are commonly used, namely substitution techniques and transposition techniques. One of the weaknesses of the basic cryptographic techniques is the lower level of data security. This study proposed a super encryption model in securing data by combining cryptographic algorithms with substitution techniques, i.e., autokey cipher and transposition, i.e., columnar transposition cipher. This study used the Avalanche Effect method as a measurement tool for the proposed super encryption model. The test results have shown that the proposed super encryption model can provide a better level of security. The avalanche effect test on the five data test shows that the average AE value of the proposed super encryption model is 30.76%. This value is higher than the single autokey cipher algorithm of 1.66% and column transposition with a value of 18.03%. Other results from the five data test have shown that the proposed model has a high level of accuracy of 100% in terms of the decryption process results, which is the same as the initial data before going through the encryption process.

Keamanan data atau informasi menjadi topik yang selalu diperbincangkan khalayak ramai, kerahasiaan data dan informasi menjadi hal yang sangat penting untuk dijaga. Tetapi Kejahatan cyber makin sering kita dengar di media masa. Pelaku kejahatan memanfaatkan celah keamanan yang terdapat dalam sistem, untuk dimasuki dan dilakukan manipulasi sebuah data atau informasi. Kriptografi saat ini menjadi salah satu solusi yang banyak diminati karena sudah terbukti bisa mengamankan data dan informasi secara efektif. Bahkan, kriptografi sudah ada di dalam kehidupan kita saat ini, mulai dari transaksi di mesin ATM, Credit Card, mengakses internet, percakapan melalui telepon genggam sampai transaksi di dalam perdagangan elektronik (e-commerce). Pada penelitian ini digunakan metode algoritma Stream Cipher dan Hill Cipher. Berdasarkan hasil perbandingan antara kedua metode algoritma tersebut, dapat disimpulkan bahwasannya algoritma Stream Cipher dapat menjadi pilihan untuk mengamankan dan meminimalisir kebocoran data dan Informasi.
