A Role-Based Access Control Management Model on Blockchain for Restricted Facilities: An Airport Example

Since numerous firms and governments are in dire need of safeguarding their premises, the confidentiality of data is of utmost importance in achieving this goal. The security of facility entry is crucial, but it's also crucial for future demands that the entrance logs are auditable. Due to these reasons, restricted locations require access control and round-the-clock management. A centralized approach for administering grants and monitoring access is a simple choice as it is among the most frequently employed ones. In this respect, airports are deemed as being one of the safest places since every airport provides certain public and security services and accession to these restricted facilities must be controlled and authorized by the airport management organization. Unchangeable, auditable and always-available access records and open management in accordance with its confidentiality necessities are all answers to the issues experienced in the sector with regard to access control. In this work, a role-based access control strategy for regulating airport entrances that are scattered and require government oversight is presented and implemented using the Ethereum blockchain. Our obtained results demonstrate the adaptability and also utility of our proposal for other restricted facilities that have similar requirements.
