Transformasi Digital Enkripsi Teks: Implementasi Playfair Cipher pada Platform Google Colaboratory
Abstract
Digital transformation requires a reliable information security system, especially in protecting text data on public networks. This study aims to implement and evaluate the classic Playfair Cipher algorithm using the Google Colaboratory platform. The method used is quantitative descriptive, with testing conducted on English-language text using the Python programming language. The results show that the algorithm is capable of encrypting and decrypting data accurately, with an average encryption processing time of 7.32 ms and decryption time of 10.86 ms. Security validation through frequency and bigram analysis proves the algorithm's effectiveness in obscuring the original text pattern. The conclusion of this study indicates that the Playfair Cipher algorithm remains relevant as an efficient, accurate, and practically integrable solution for simple text encryption on cloud platforms for educational and data security protection needs.

Abstrak
Transformasi digital menuntut sistem keamanan informasi yang andal, khususnya dalam perlindungan data teks di jaringan publik. Penelitian ini bertujuan mengimplementasikan dan mengevaluasi algoritma klasik Playfair Cipher menggunakan platform Google Colaboratory. Metode yang digunakan adalah deskriptif kuantitatif, dengan pengujian dilakukan pada teks berbahasa Inggris menggunakan bahasa pemrograman Python. Hasil menunjukkan bahwa algoritma mampu mengenkripsi dan mendekripsi data secara akurat, dengan rata-rata waktu proses enkripsi 7,32 ms dan dekripsi 10,86 ms. Validasi keamanan melalui analisis frekuensi dan bigram membuktikan efektivitas algoritma dalam menyamarkan pola teks asli. Simpulan dari penelitian ini menunjukkan bahwa algoritma Playfair Cipher masih relevan sebagai solusi enkripsi teks sederhana yang efisien, akurat, dan dapat diintegrasikan secara praktis dalam platform cloud untuk kebutuhan edukasi dan perlindungan keamanan data.
