Abstract

Perkembangan layanan digital terdistribusi mendorong kebutuhan sistem manajemen akses yang tetap aman dan tersedia pada kondisi jaringan tidak stabil. Permasalahan utama pada arsitektur master-distributed client adalah proses autentikasi dan otorisasi yang umumnya bergantung pada server pusat, sehingga layanan berisiko terganggu ketika koneksi ke Master Node mengalami delay tinggi atau terputus. Penelitian ini menawarkan S4RAS (Solution for Remote Area Services), yaitu prototipe manajemen akses layanan berbasis Master-Distributed Client dengan autentikasi hibrida, otorisasi RBAC/ABAC, proteksi API menggunakan JWT RS256, keystore lokal, cache policy, auth log dan mekanisme policy synchronization. Pengujian dilakukan pada lingkungan eksperimen lokal dengan tiga kondisi yaitu normal, jaringan tidak stabil menggunakan delay satu arah 400 ms dan offline. Hasil pengujian menunjukkan login valid berhasil 100% dan login tidak valid ditolak 100% pada seluruh kondisi. Authentication response time memiliki mean 95,185 ms pada kondisi normal, 508,019 ms pada kondisi tidak stabil dan 98,796 ms pada kondisi offline. Token validation time memiliki mean 2,869 ms pada kondisi normal, 411,022 ms pada kondisi tidak stabil dan 3,105 ms pada kondisi offline. Service response time tetap rendah dengan mean 5,322 ms pada kondisi normal, 7,189 ms pada kondisi tidak stabil dan 4,964 ms pada kondisi offline. Policy synchronization delay tercatat dengan mean 498,622 ms pada kondisi normal dan 472,807 ms pada kondisi tidak stabil. Service availability mencapai 100% pada 256 request untuk setiap kondisi uji. Dengan demikian, S4RAS mampu mempertahankan kontrol akses dan ketersediaan layanan melalui kombinasi kontrol terpusat pada master dan validasi lokal pada distributed client.

The growth of distributed digital services requires an access management system that remains secure and available under unstable network conditions. The main problem in a master-distributed client architecture is that authentication and authorization commonly depend on a central server, causing service disruption risks when the connection to the Master Node experiences high delay or becomes unavailable. This study proposes S4RAS (Solution for Remote Area Services), a service access management prototype based on a Master-Distributed Client architecture using hybrid authentication, RBAC/ABAC authorization, JWT RS256 API protection, local keystore, policy cache, auth log, and policy synchronization. The system was tested in a local experimental environment under three conditions: normal network, unstable network with 400 ms one-way delay, and offline mode. The results show that valid logins achieved 100% success and invalid logins were rejected 100% across all conditions. Authentication response time reached a mean of 95.185 ms in normal condition, 508.019 ms in unstable condition, and 98.796 ms in offline condition. Token validation time reached a mean of 2.869 ms in normal condition, 411.022 ms in unstable condition, and 3.105 ms in offline condition. Service response time remained low with a mean of 5.322 ms in normal condition, 7.189 ms in unstable condition, and 4.964 ms in offline condition. Policy synchronization delay reached a mean of 498.622 ms in normal condition and 472.807 ms in unstable condition. Service availability reached 100% across 256 requests in each test condition. Therefore, S4RAS can maintain access control and service availability by combining centralized control at the master and local validation at the distributed client.
