Research on access control for secure cross-domain data circulation
Year: 2025
Type: article
Abstract: To address security risks such as tampering, leakage, and misuse of information stemming from inconsistent authorization mechanisms in data element circulation, the focus was placed on secure cross-domain data circulation. Initially, the challenges associated with cross-domain data access control were systematically examined, followed by an in-depth investigation into the fundamental concepts of cross-domain data circulation and the essential implications of cross-domain access control. Subsequently, a comprehensive review was conducted on access control technologies for secure cross-domain data circulation, which encompassed: access control models categorized as provenance-based, purpose-based, and cyberspace-oriented approaches; key policy management technologies involving label mining for policies, policy negotiation and generation, conflict detection and resolution, policy propagation and enforcement, and auditing of anomalous policy execution; policy implementation mechanisms developed based on blockchain technology, data capsules, and data infrastructure. Finally, current challenges in cross-domain data circulation are systematically summarized, and future research directions are proposed.
