Traditional multi-level security (MLS) systems have the defect of centralizing authorized facilities, which is difficult to meet requirements modern distributed peer-to-peer network architecture. Blockchain widely used in field access control with its decentralization, traceability and non-defective modification. Combining blockchain technology Bell-LaPadula model, we propose a new named BC-BLPM, for MLS environment. The "multi-chain" architecture dividing resources into isolated domains, providing fine-grained data protection mechanism. policies are implemented by smart contracts deployed each domain, so that side chains different domains storage records from outside maintain integrity records. Finally, implement BC-BLPM prototype system using Hyperledger Fabric. experimental analyt-ical results show model can adapt well needs environment, it has feasibility application actual scenarios.
