Abstract: In order to ensure the security and privacy of the operational data sharing in the air traffic management system, a security sharing scheme for the operational data is proposed. The dual public key encryption mechanism is innovatively integrated into the consortium blockchain system. Based on the identity-based encryption algorithm, the public key of the supervisor entity is embedded into the ciphertext. In this way, both the supervisor and the data user can independently decrypt and obtain the strictly consistent plaintext information, without the complex communication protocol proving the equality of the message. Not only it ensures the confidentiality of air traffic management operational data, but also it provides a guarantee for the efficient accessing and effective supervision. Experimental comparison and analysis show that the proposed scheme has high security performance and execution efficiency. It has a good application prospect in the field of air traffic data operation and sharing.
