A Proposed Navigation Message Authentication Implementation for Civil GPS Anti-Spoofing

Kyle D. Wesson, Mark P. Rothlisberger, and Todd E. Humphreys

Abstract:	A specific implementation of navigation message authentication (NMA) for civil GPS anti-spoofing is proposed. The notion of GNSS signal authentication is defined in probabilistic terms. This work proposes a practical, backward-compatible NMA strategy for the civil L2/L5 civil navigation (CNAV) message. The proposal is sufficiently detailed to facilitate near-term implementation of security-hardened civil GPS.
