DEFCON - Dynamic Testbed for secur open service navigation

The objective of this project is to design, implement and validate four authentication schemes which can provide secure GNSS-based navigation to open service users. The authentication schemes will provide the end-users the following capabilities:

• Navigation Message Authentication (NMA) to provide navigation data source authenticity and data integrity validation.
• Autonomous Spoofing Protection (ASP) to provide protection against spoofing and replay attacks.
