Distributed attribute-based access control system using permissioned blockchain

Auditing provides essential security control in computer systems by keeping track of all access attempts, including both legitimate and illegal attempts. This phase can be useful the context audits, where eventual misbehaving parties held accountable. Blockchain technology provide trusted auditability required for systems. In this paper, we propose a distributed Attribute-Based Access Control (ABAC) system based on blockchain to auditing Besides auditability, our presents level transparency that requesters resource owners benefit from it. We present architecture with an implementation Hyperledger Fabric, achieving high efficiency low computational overhead. The proposed solution is validated through use case independent digital libraries. Detailed performance analysis presented, taking into account different consensus mechanisms databases. experimental evaluation shows presented effectively handle transaction throughput 270 transactions per second, average latency 0.54 seconds transaction.
