This paper proposes an candidate implementation of a navigation message authentication based on the TESLA broadcast authentication protocol, tailored specifically to the Galileo E1 OS navigation message structure. Constrained by the potentially available unallocated space in the current Galileo E1 OS message structure, the proposed solution is optimized and refined with respect to a set of relevant performance criteria. A performance and security analysis is then presented, considering a typical mass-market or civilian user operating in a selection of typical environments, including the AWGN and the LMS channels.. In this manner the paper explores the capacity and the limitations of a message-based authentication solution in the context of the typical civilian user.
