Apparatus for securing communication

An apparatus configured to establish a secure communication between a first and second communication device, wherein the apparatus is configured to:

• determine a current geodetic position of the one of the first and second communication devices;
• compare the current geodetic position of the one of the first and second communication devices with a received position or stored position of the one of the first and second communication devices or check plausibility of the received position or stored position of the one of the first and second communication devices based on the current geodetic position of the one of the first and second communication devices,
• wherein the current geodetic position of the one of the first and second communication devices is determined based on an angle of arrival or a signal strength of communication signals received by the one of the first and second communication devices from one or more satellites, and
• wherein a transmit time of signals received by the one of the first and second communication devices from the one or more satellites is also used to determine the current geodetic position of the one of the first and second communication devices.

A method of attempting to establish a secure communication between a first and second communication device, the method comprising:

• determining a current geodetic position of the one of the first and second communication devices;
• comparing the current geodetic position of the one of the first and second communication devices with a received position or stored position of the one of the first and second communication devices or check plausibility of the received position or stored position of the one of the first and second communication devices based on the current geodetic position of the one of the first and second communication devices;
• and
• establishing or terminating the secure communication between the first and second communication device based on the comparison or the plausibility check,
• wherein the current geodetic position of the one of the first and second communication devices is determined based on an angle of arrival or a signal strength of communication signals received by the one of the first and second communication devices from one or more satellites, and
• wherein a transmit time of signals received by the one of the first and second communication devices from the one or more satellites is also used to determine the current geodetic position of the one of the first and second communication devices.
