  "title": "Method and device for external operation of a device",
  "abstract": "A method for external use of a device having a wireless communication interface by a program of a mobile device. External use is possible only when a key device serving as an authentication token communicates with the program. This increases the security of an entry method for a vehicle.",
  "claims": [
    "1. A method for external use of a device having a wireless communication interface by a program of a mobile device, the method comprising: detecting when a key device serving as an authentication token communicates with the program of the mobile device; and enabling the external use of the device to be controlled by the mobile device only when the key device is communicating with the program of the mobile device, wherein the external use is enabled only while a dead man function of the key device remains activated, wherein the key device is a vehicle key and the device is a vehicle, and wherein the dead man function is a switch on the key device.",
    "2. The method of claim 1, wherein the key device communicates with the mobile device via a short range wireless link.",
    "3. The method of claim 1, wherein the key device communicates with the device via the program.",
    "4. The method of claim 1, wherein the connection between the key device, the device and/or the mobile device is secured.",
    "5. The method of claim 1, wherein the connection between the key device, the device and/or the mobile device is secured by an asymmetric encryption method.",
    "6. The method of claim 1, further comprising checking a presence of the key device by a repeatedly performed challenge response authentication scheme.",
    "7. The method of claim 1, wherein the external use is not initiated and/or is interrupted if there is no communication between the key device and the device and/or between the key device and the mobile device.",
    "8. The method of claim 1, wherein the device and the mobile device communicate with one another using a Bluetooth Low Energy protocol.",
    "9. The method of claim 1, wherein the device is a vehicle and the external use comprises one of starting, opening, or driving the vehicle.",
    "10. An apparatus for external use of a device, the apparatus comprising: a mobile device having a program for external use of the device, wherein the device and the mobile device each have a wireless communication interface configured for communication between device and mobile device, a key device serving as an authentication token, wherein the key device and the mobile device each have a wireless communication interface configured for communication between key device and mobile device wherein the mobile device and the device are configured so that external use of the device controlled by the mobile device is initiated only when the key device communicates with the mobile device and/or the device, and wherein the key device comprises a dead man function, wherein the external use is possible only while a dead man function of the key device remains activated, and wherein the dead man function is a switch on the key device.",
    "11. The apparatus of claim 10, wherein the device is a vehicle.",
    "12. The apparatus of claim 10, wherein the device is a vehicle and external use comprises one of starting, opening or driving the vehicle.",
    "13. A method for external use of a device having a wireless communication interface by a program of a mobile device, the method comprising: detecting when a key device serving as an authentication token communicates with the program of the mobile device; and enabling the external use of the device controlled by the mobile device only when the key device is communicating with the program of the mobile device, wherein the external use is enabled only while a dead man function of the key device remains activated, and wherein the dead man function is a switch on the key device."

  "description_excerpt": "Illustrative embodiments relate to a method and an apparatus for external use of a device, for example, of a vehicle.\n\nDisclosed embodiments are explained with reference to the associated drawings, in which:\n\nFIG. 1 shows a schematic representation of an apparatus for external use of a device; and\n\nFIG. 2 shows a flowchart of a method for external use of a device.\n\nAt present, active assistance functions are being developed that involve the driver controlling the motion of his vehicle from the outside using a smartphone. Applications therefor are parking maneuvers or maneuvers with a trailer, for example. Benefits for the driver may be the use of especially tight parking spaces or a better overall view of the maneuver from the outside.\n\nSmartphones are unsecure systems, however, especially in the interface between touchscreen as the central input element and an application being attackable/manipulable in various ways, both by the user and against him.\n\nThe communication relationship that is deemed unsecure within the smartphone can easily be compromised both by malware such as a virus or the like and by supplementary components that the user consciously installs, because operating systems used today provide few or no protective mechanisms in this regard and/or come from an open source background anyway and are therefore manipulable by anyone.",
