Fast Settlement Scheme of Aviation Business Privacy Preservation Based on Consortium Blockchain
Xingguang Zhou, Ziyu Meng, Yi Liu · 2021
In order to reduce the risk of privacy leakage in the process of aviation business consumption and settlement, a privacy preservation scheme for aviation business consumption data is proposed. The dual public key encryption mechanism is innovatively integrated into the consortium blockchain system. The additional recipient's public key is added to the ciphertext, so that both recipients can decrypt independently and obtain the same plaintext information. Experimental comparative analysis shows that the scheme only increases a little computational complexity, while an additional recipient is added with high execution efficiency. Not only the scheme realizes the privacy preservation for passengers and enterprise customers, but also ensures the precise settlement and rapid audit of consumption data between airlines and enterprise customers.
