Secure Multi-Keyword Retrieval with Integrity Guarantee for Outsourced ADS-B Data in Clouds

With the development of Automatic Dependent Surveillance-Broadcast (ADS-B) technology in the aviation industry, a large amount of data are generated in ADS-B systems everyday. Cloud storage can satisfy the requirement of storing a large amount of ADS-B data well, however, the data stored on cloud server also raises problems about the security and confidentiality. This paper proposes a secure ADS-B data outsourcing scheme with integrity guarantee and multi-keyword retrieval (MRDP) to address these issues. In our MRDP, an index is generated for each piece of ADS-B data through Bloom filters to enable multi-keyword retrieval from clouds. Also, a unique label is produced for each piece of ADS-B data for integrity verification of query results. Our MRDP solution enjoys completeness property in that all query results with regard to the multiple keywords would be returned by the cloud server, otherwise it could be detected by the user. Security analysis indicated that our scheme offers integrity, completeness and privacy protection on outsourced ADS-B data, under the computational Diffie-Hellman (CDH) assumption and the discrete logarithm (DL) assumption. Theoretical and experimental analyses demonstrate the practicality of our proposed MRDP construction compared to existing solutions.

I. Introduction

In recent years, with the rapid development of the aviation industry, air traffic control (ATC) has become increasingly important. ATC is a system that monitors and coordinates aircraft underway, optimizing flight spacing and flight paths while ensuring the safe and orderly operation of the aviation network. Automatic Surveillance Broadcasting (ADS-B) is a new navigation technology, which enables the management and surveillance of traffic monitoring and messaging through the utilization of air-to-ground and air-to-air data links. The ADS-B system uses ADS-B data as a carrier to transmit the aircraft’s navigation situation to the ATC system, which would help the ATC system command the aviation network. In the event of a navigation accident, ADS-B data are the key evidence in investigating the cause of the occurrence of the accident and conducting accountability. However, the existing ADS-B systems lack security protection mechanisms [1]. If ADS-B data is maliciously tampered with, it may lead to ineffective accountability for aviation safety accidents [2]. Therefore, protecting the security of ADS-B data is extremely important for aviation safety.
