MODEL KEAMANAN DOKUMEN DIGITAL DENGAN ADVANCED ENCRYPTION STANDARD 256 DAN SOULBOUND TOKEN PADA PLATFORM BLOCKCHAIN

RIFALDI, REGIS SYAWALUDIN - Personal Name;

ABSTRAK

Manajemen data konvesional yang terpusat rentan terhadap pelanggaran data masif dan single of failure, yang secara signifikan mengacam keamanan informasi dan kepercayaan publik. Untuk mengatasi kelemahan fundamental ini, penelitian ini mengusulkan perancangan sebuah model keamanan dokumen yang mengintegrasikan tiga pilar teknologi utama, yaitu blockchain untuk menjamin integritas dan ketertelusuran data, enkripsi Advanced Encryption Standard (AES)-256 untuk menjaga kerahasiaan dokumen, dan Soulbound (SBT) sebagai sistem autentikasi terdesentralisasi yang tidak dapat dipindahtangankan. Menggunakan metodologi Design Science Research (DSR), sistem dirancang dan kemudian kinerjanya dievaluasi melalui serangkaian pengujian terukur pada proses unggah-unduh dan biaya transaksi on-chain. Hasil pengujian menunjukkan proses unggah memiliki bottleneck pada interkasi on-chain, yang menyumbang sekitar 88% dari total waktu rata-rata 56 detik. Sebaliknya, proses unduh dengan waktu rata-rata 2.8 detik, di mana kinerjanya lebih bergantung pada kecepatan jaringan internet. Analisis biaya membuktikan bahwa gas fee bersifat independen dari ukuran file, dengan biaya rata-rata 0.00025 ETH untuk penerbitan SBT dan 0.00048 ETH untuk pencatatan dokumen.

ABSTRACT

Conventional centralized data management is vulnerable to massive data breaches and single point of failure, which significantly threatens information security and public trust. To address this fundamental weakness, this research proposes the design of a hybrid digital document security model that integrates three main technological pillars, that is blockchain to ensure data integrity and traceability, Advanced Encryption Standard (AES)-256 encryption to maintain document confidentiality, and Soulbound Token (SBT) as a non-transferable decentralized authentication system. Using the Design Science Research (DSR) methodology, the system was designed and its performance was subsequently evaluated through a series of measured tests on upload-download processes and on-chain transaction consts. The results show that the upload process is bottlenecked by on-chain interactions, which account for approximately 88% of the total average time of 56 seconds. Conversely, the download, with an average time of 2.8 seconds, where its performance is more dependent on internet network speed. The cost analysis proves that the gas fee is independent of file size, with average costs of 0.00025 ETH for SBT issuance and 0.00048 ETH for document.

Keywords: AES-256 encryption, blockchain, document security, soulbound token, system performance
