Embodiment Construction

[0064] Parts corresponding to each other in the following embodiments are denoted by the same reference numerals.

[0065] figure 1 A smart card 102 is shown with a protected storage medium 104 . The memory contains one or more keys 120a for performing the distance boundary protocol. The memory may contain a further key 138a for secure transmission of position data from the locating unit to the smart card. In addition, the protected memory contains data 121 such as personal data of the user issued with the smart card. These data may consist of, for example, user account information, signature keys, and the like. The smart card is able to execute the distance boundary protocol through a module 123 a interacting with a corresponding module 123 b of the positioning unit 130 . In addition, the smart card has a processor 106 which is able to execute a smart card function 110 using the location data, preferably after the locating unit has been authenticated to the smart card. T...

Abstract

In some applications the problem arises that the location data derived by the smart card from an external source has the same confidential status as the data stored on the smart card. In order to solve this problem, a method for providing location data to a smart card (102) is proposed, including the following parts: receiving (202) or determining the location data of the location unit (130) through a location unit (130), wherein the location unit ( 130) is spaced apart from the smart card (102); the location data is transmitted (204) from the positioning unit (130) to the smart card (102) through a non-contact interface (118) in the case of an encryption protocol (114) ; Execute (206) the distance boundary protocol (112) between the smart card (102) and the positioning unit (130), wherein the distance boundary protocol (112) is just within the spatial distance between the smart card (102) and the positioning unit (130) Successfully terminated when the specified maximum distance is not exceeded; when the distance boundary protocol (112) is successfully terminated, the smart card function (110) is executed (210), wherein the smart card function (110) uses the transmitted location data as an indication that the smart card ( 102) the location data of the current location.

Description

technical field [0001] The invention relates to a method for reliably providing position data from a locating unit to a smart card, as well as to a corresponding smart card, a corresponding locating unit and a computer program product. Background technique [0002] A method for reliably determining the spatial distance of two physically separated units or devices is known in the prior art. In particular publication US 2011 / 0078549 A1 shows a reading device for determining the validity of a connection to a transponder, which is designed to measure the response time of the transponder and to authenticate in two separate steps the transponder. This publication also discloses a transponder for determining the validity of a connection to a reading device, wherein the transponder is designed to provide information to the reading device in order to measure the response time and to be used in two separate An authentication is carried out in a step in which at least some data are t...
