Concept for data authentication and secured localization based on a satellite navigation signal

摘要

Embodiments of the present invention provide a satellite navigation receiver. The satellite navigation receiver comprises a receiver unit and a transmitter or a controller. The receiver unit is configured to receive and process a satellite navigation signal from a satellite navigation system at the certain time, to obtain a received signal, the received signal comprising a first component in a digital form, wherein the first component in the digital form is encrypted. The transmitter is configured to transmit the first component in the digital form together with an identification of a user of the satellite navigation receiver at the certain time. The controller is configured to store the first component in the digital form on a non-volatile storage medium in association with other data representing an information from a location, at which the satellite navigation receiver was located at the certain time.
