SBAS Data Authentication: A Concept of Operations

Andrew Neish, Todd Walter and J. David Powell

Abstract:	Previous work in data authentication for SBAS has focused on the authentication schemes and the key management architecture. As these designs mature, concepts of receiver operations need to be defined before any impacts to the SBAS service can be evaluated. In this work, several authentication schemes are put forward along with a concept of operations (CONOPS) that defines how receivers act on authenticated and unauthenticated information. The CONOPS developed here allow SBAS services providers to incorporate data security while producing minimal impacts to performance for users.
