Abstract:
Global Navigation Satellite Systems (GNSS) are a key enabler for many new technologies, ranging from autonomous vehicles to shared mobile devices. In many use cases, GNSS augmentation systems are required to provide the correction data needed to achieve centimeter-level accuracy. These systems can be offered as paid services, with correction data broadcast via satellite. In order to protect these systems and restrict access to paying users only, encryption mechanisms must be adopted. SPARTN is an open industry standard for GNSS augmentation that has been specifically designed to support encryption, while saving bandwidth on the satellite link. In this seminar, we will introduce APBE (Anti-Piracy Broadcast Encryption), a method designed to enhance the SPARTN security by protecting against pirate customers while minimizing bandwidth and storage requirements. The feasibility of the proposed approach has been demonstrated via a real proof-of-concept implementation based on an embedded system, and it is protected by the patent US 12452050 B2 granted on 2025-10-21.
