Making air traffic surveillance more reliable: a new authentication framework for automatic dependent surveillance-broadcast (ADS-B) based on online/offline identity-based signature


  • This paper is an extended version of the paper “An Authentication Framework for Automatic Dependent Surveillance-Broadcast Based on Online/Offline Identity-Based Signature”, presented at the Eight International Conference on P2P, Parallel, Grid, Cloud and Internet Computing (3PGCIC-2013), Compiegne, France, October 2013. The paper has been fully revised so that the current version contains more precise description of the framework, more detailed security and performance analysis, and further elaboration on the ADS-B system and its security.

Automatic dependent surveillance-broadcast is an emerging surveillance technology for the future “e-enabled” aircrafts, which will make it possible for aircrafts to share their location data with neighboring aircrafts, ground controllers, and other interested parties. In order to provide the automatic dependent surveillance-broadcast communications with a high level of accuracy and integrity, a reliable authentication mechanism is required. So far, however, very few cryptographic solutions have been offered to achieve this in the literature. Even existing solutions have faced the following challenges: (i) the authentication solutions based on regular digital signature require complex management of public-key infrastructureell; and (ii) signing messages exchanged or broadcast frequently in aircraft-to-aircraft and aircraft-to-ground communication modes can cause a computational bottleneck easily. In order to address these challenges, we take a fresh approach to building up an authentication framework by introducing a new online/offline identity-based signature scheme. Our scheme will resolve the public-key infrastructure management issue by using the identities of aircrafts as public keys and will achieve a high efficiency through online/offline signature generation.
