Low Latency Authentication of Navigation Message
Abstract
The primary objective of this research is to develop low-latency authentication methods in the Global Navigation Satellite System (GNSS). The proposed approach is to superimpose the authentication tag onto the navigation message and transmit them simultaneously within the same frequency band. This innovative approach enables instantaneous authentication, as both the navigation message and the authentication tag are received simultaneously. A comprehensive evaluation was conducted, focusing on key performance metrics such as the Authentication Error Rate (AER), Time Between Authentications (TBA), and Authenticated Throughput. To further reduce authentication latency, we investigated the option of segmenting the navigation message into multiple segments, enabling simultaneous transmission alongside the authentication tag. This segmentation approach showcased notable gains in authentication latency, leading to faster and more efficient verification processes. Moreover, our proposed method exhibited a substantial improvement in authenticated throughput compared to existing techniques.
