Abstract

Algoritma kriptografi lightweight dirancang sedemikian sehingga dapat diterapkan pada suatu perangkat IoT yang terbatas. Salah satu cipher yang termasuk ke dalam kriptografi lightweight adalah Present Cipher. Menurut beberapa artikel, Present Cipher sangat efisien dari segi hardware maupun software sehingga Present Cipher menjadi contoh terbaik dari algoritma kriptografi lightweight. Terlebih lagi Present Cipher telah distandarisasi oleh ISO/IEC. Present Cipher merupakan Blok Cipher dengan skema SPN sehingga dibutuhkan suatu mode operasi. Oleh karena itu, dipilih Cipher Block Chaining sebagai mode operasi pada penelitian ini. Penelitian ini bertujuan untuk memperoleh pengamanan pesan teks dengan kriptografi lightweight Present Cipher pada Cipher Block Chaining dan mengimplementasikannya dalam sebuah aplikasi menggunakan bahasa pemrograman Python. Berikutnya aplikasi tersebut divalidasi dengan bantuan Excel. Hasil dari penelitian ini berupa aplikasi yang dapat digunakan pengguna untuk mengamankan pesan teks dengan kriptografi lightweight Present Cipher pada Cipher Block Chaining. The Lightweight Cryptography algorithm is design in such a way that it can be implemented on a constrained IoT device. One of the ciphers falling under lightweight cryptography is the Present Cipher. According to several articles, the Present Cipher is highly efficient in terms of both hardware and software, making it an excellent example of lightweight cryptography algorithms. Moreover, Present Cipher has been standardized by ISO/IEC. Present Cipher is a Block Cipher with an SPN scheme, requiring a mode of operation. Therefore, Cipher Block Chaining was chosen as the mode of operation in this study. The objective of this research is to achieve secure plaintext communication using lightweight cryptography Present Cipher in Cipher Block Chaining mode and to implement it in an application using the Python programming language. Furthermore, this application is validated with the assistance of Excel. The outcome of this research is an application that allows users to secure plaintext messages using lightweight cryptography Present Cipher in Cipher Block Chaining mode.
