Abstract

Peningkatan ancaman siber terhadap data medis elektronik di Indonesia memerlukan solusi keamanan yang inovatif. Penelitian ini mengembangkan sistem manajemen rekam medis elektronik terdesentralisasi dengan mengintegrasikan teknologi blockchain, InterPlanetary File System (IPFS), Key Management System (KMS), dan algoritma Semantic-Aware Hierarchical Encryption (SAHE). Metodologi penelitian menggunakan pendekatan eksperimental dengan implementasi sistem yang mengombinasikan blockchain untuk metadata, IPFS untuk penyimpanan off-chain, dan SAHE untuk enkripsi berlapis berdasarkan tujuh level sensitivitas data medis. Evaluasi dilakukan melalui pengujian performa, keamanan, dan kontrol akses multi-peran. Hasil penelitian menunjukkan sistem memiliki kinerja efisien dengan penggunaan CPU rata-rata 55% dan memori 80,2 MB. Evaluasi keamanan menggunakan differential cryptanalysis menunjukkan probabilitas diferensial maksimum 3,12% (di bawah ambang aman 6,25%), sementara pengujian OWASP ZAP mengonfirmasi tidak ada kerentanan kritis. Pengujian kontrol akses membuktikan sistem berhasil membatasi akses data sesuai hierarki pengguna - dokter mendapat akses penuh, perawat terbatas pada data klinis, dan administrator hanya data demografis.

The increasing cyber threats against electronic medical data in Indonesia requires innovative security solutions. This research develops a decentralized electronic health record management system by integrating blockchain technology, InterPlanetary File System (IPFS), Key Management System (KMS), and Semantic-Aware Hierarchical Encryption (SAHE) algorithm. The research methodology uses an experimental approach with system implementation that combines blockchain for metadata, IPFS for off-chain storage, and SAHE for layered encryption based on seven levels of medical data sensitivity. Evaluation was conducted through performance testing, security assessment, and multi-role access control testing. Results show the system has efficient performance with average CPU usage of 55% and memory consumption of 80.2 MB. Security evaluation using differential cryptanalysis shows maximum differential probability of 3.12% (below safe threshold of 6.25%), while OWASP ZAP testing confirms no critical vulnerabilities. Access control testing proves the system successfully limits data access according to user hierarchy - doctors get full access, nurses limited to clinical data, and administrators only demographic data.
