Research on Access Control of SWIM Data Sharing Based on Attribute Based Encryption

As a standard implemented by ICAO (International Civil Aviation Organization), SWIM (System Wide Information Management) is a sharing mechanism for global flight operation data, which adopts a service-oriented architecture SOA (Service Oriented Architecture) to carry heterogeneous flight operation data from multiple sources. In order to solve the problems of data security and privacy in flight operation data sharing, this paper proposes an access control architecture for flight operation data sharing based on ABE (Attribute-based Encryption) for SWIM, correlates the refined flight operation data attributes with the private keys of SWIM aviation users, establishes an attribute association matrix, and realizes a fine-grained access policy for flight operation data sharing.
