PROVIDING POSITION DATA BY MEANS OF A DISTANCE-BOUNDING PROTOCOL

摘要

A method is proposed for providing position data for a chip card having portions for receiving or detecting position data of a localisation unit by the localisation unit, wherein the localisation unit is spatially separate from the chip card; transmitting the position data from the localisation unit to the chip card via a contactless interface with use of a cryptographic protocol; executing a distance-bounding protocol between the chip card and the localisation unit, wherein the distance-bounding protocol then concludes successfully precisely when the spatial distance between the chip card and localisation unit does not exceed a predefined maximum distance; and executing a chip card function with successful conclusion of the distance-bounding protocol, wherein the chip card function uses the transmitted position data as position data specifying the current position of the chip card.

1. A method for providing position data for a chip card having portions for:
receiving or detecting position data of a localisation unit by the localisation unit, wherein the localisation unit is spatially separate from the chip card; transmitting the position data from the localisation unit to the chip card via a contactless interface with use of a cryptographic protocol; executing a distance-bounding protocol between the chip card and the localisation unit, wherein the distance-bounding protocol then concludes successfully precisely when the spatial distance between the chip card and localisation unit does not exceed a predefined maximum distance; and executing a chip card function with successful conclusion of the distance-bounding protocol, wherein the chip card function uses the transmitted position data as position data specifying the current position of the chip card.
