Abstract

Meningkatnya risiko penyadapan data sensitif di era digital menuntut solusi keamanan yang memiliki tingkat keamanan tinggi, tetapi juga mampu dalam menyembunyikan keberadaan data agar tidak menarik perhatian. Penelitian ini menjawab tantangan tersebut dengan merancang menguji aplikasi berbasis web yang mengkombinasikan Algoritma Encryption Standard (AES) dengan metode noiseless steganography berbasis permainan Minesweeper. Metode penelitian yang digunakan adalah Design & Development (D&D), yang tahapannya meliputi perancangan sistem, implementasi berbasis web, dan pengujian yang terdiri dari black-box testing, analisis avalanche effect, serta survei persepsi visual. Hasil pengujian menunjukkan bahwa seluruh fungsionalitas aplikasi berjalan sesuai rancangan. Algoritma AES-128 terbukti menyediakan tingkat keamanan yang baik, dibuktikan melalui hasil uji avalanche effect yang menunjukkan nilai perubahan bit antara 45,83% hingga 53,91%. Angka ini mendekati nilai ideal 50%, menandakan bahwa algoritma kriptografi yang digunakan memiliki ketahanan yang kuat terhadap serangan analisis. Metode steganografi pada Minesweeper terbukti efektif, analisis Skala Likert dari survei persepsi visual menghasilkan skor rata-rata 2.48, yang menandakan bahwa metode yang digunakan memiliki kualitas penyamaran yang baik dan tidak menimbulkan kecurigaan. Penelitian ini menyimpulkan bahwa kombinasi AES dan noiseless steganography pada Minesweeper merupakan solusi efektif untuk mengamankan data secara kriptografis sekaligus menyamarkan keberadaannya. ----- The increasing risk of sensitive data interception in the digital era demands security solutions that are not only highly secure but also capable of concealing the existence of the data to avoid attracting attention. This research addresses this challenge by designing and testing a web-based application that combines the Advanced Encryption Standard (AES) algorithm with a noiseless steganography method based on the Minesweeper game. The research method used is Design & Development (D&D), which includes system design, web-based implementation, and testing comprised of black-box testing, avalanche effect analysis, and a visual perception survey. The results show that all application functionalities performed as designed. The AES-128 algorithm was proven to provide a high level of security, evidenced by avalanche effect test results showing a bit change rate between 45.83% and 53.91%. This range is close to the ideal 50%, indicating that the cryptographic algorithm possesses strong resistance to analytical attacks. The Minesweeper steganography method proved effective; a Likert scale analysis from the visual perception survey yielded a mean score of 2.48, indicating that the method possesses good concealment quality and does not arouse suspicion. This research concludes that the combination of AES and noiseless steganography in Minesweeper is an effective solution for cryptographically securing data while simultaneously concealing its existence.
