Description

Technical Field

[0001] This invention relates to a geolocation communication device, belonging to the field of mimicry defense technology. Background Technology

[0002] Currently, IP address-based communication has matured significantly after decades of development, offering advantages such as high communication speed and established applications. However, in certain communication scenarios, IP address-based communication often fails to accurately or even obtain the geographical location of the communicating parties, requiring the assistance of specific applications or devices to determine their location. To meet high-security communication requirements, a geolocation communication device is needed to quickly determine the location of communicating parties within the network, thereby improving the positioning capabilities of network devices. Summary of the Invention

[0003] In order to overcome the problems existing in the prior art, the present invention provides a geographic location communication device.

[0004] This invention provides a geographic location communication device, comprising: a geographic location communication server and a location communication device;

[0005] The location communication device is used to obtain geographical location information;

[0006] The geographic location communication server is equipped with an IP conversion interface and a location communication interface;

[0007] The IP conversion interface has the function of a DHCP server and is interconnected with network devices; it is used to hand over data packets sent by network devices to the geolocation communication server for processing after receiving them.

[0008] The location communication interface is interconnected with the location communication device and is used to hand over the data packets sent by the location communication device to the geographic location communication server for processing after receiving them.

[0009] The communication protocol between the geographic location communication server and the network device and the location communication device adopts the method of geographic location + traditional IP protocol, that is, the IP address in the traditional IP communication protocol message is replaced with the geographic location.

[0010] Based on the above, a method to replace IP addresses in traditional IP communication protocol messages with geographical locations is as follows:

[0011] After receiving a data packet from a network device, the IP translation interface first randomly assigns a geographical location information d(x, y, h) to the network device;

[0012] The geolocation communication server records the MAC address table m of the network devices and the MAC address table p of the IP translation interface, and establishes a forwarding table f(d, m, p).

[0013] After the location communication interface receives the data packet sent by the location communication device, the geographic location communication server records the location D (X, Y, H) of the location communication device and the MAC address M of the location communication device. At the same time, it establishes a forwarding table F (D, M, P) based on the MAC address P of the location communication interface.

[0014] Network devices and location communication devices use traditional table lookup forwarding methods to conduct data communication based on forwarding tables f(d,m,p) and F(D,M,P).

[0015] Based on the above, in the forwarding table f(d, m, p), p represents the port number of the IP conversion interface, and in the forwarding table F(D, M, P), P represents the port number of the location communication interface.

[0016] Based on the above, the IP translation interface and the location communication interface in the geolocation communication server are isolated from each other.

[0017] Based on the above, the location communication device and the traditional network device also communicate using a virtual location method:

[0018] The location communication server assigns a virtual location VD(X', Y', H') to the location communication device and establishes a mapping relationship R(VD, D) with the real location D(X, Y, H) of the corresponding location communication device.

[0019] The location communication server establishes a virtual forwarding table VF(VD, M, P);

[0020] After enabling the virtual position transformation function, the value of the virtual position VD changes randomly over time;

[0021] The location communication server uses a virtual forwarding table (VF) to participate in data communication with the geolocation communication server.

[0022] This invention has outstanding substantive features and significant progress compared to the prior art. Specifically, this invention establishes a location information forwarding table through a geolocation communication server, and introduces a virtual location transformation function to hide the location information of real devices in the network, realizing a communication method for network devices based on geolocation information. This solves the problem of being unable to locate the geographical location when a fault or threat occurs in the communication system, and improves the security of communication. Attached Figure Description

[0023] Figure 1 This is a schematic diagram of the principle of the present invention. Detailed Implementation

[0024] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0025] like Figure 1 As shown, this embodiment provides a geographic location communication device, including: a geographic location communication server and a location communication device;

[0026] The location communication device is used to obtain geographical location information;

[0027] The geographic location communication server is equipped with an IP conversion interface and a location communication interface;

[0028] The IP conversion interface has the function of a DHCP server and is interconnected with network devices; it is used to hand over data packets sent by network devices to the geolocation communication server for processing after receiving them.

[0029] The location communication interface is interconnected with the location communication device and is used to hand over the data packets sent by the location communication device to the geographic location communication server for processing after receiving them.

[0030] The communication protocol between the geographic location communication server and the network device and the location communication device adopts the method of geographic location + traditional IP protocol, that is, the IP address in the traditional IP communication protocol message is replaced with the geographic location.

[0031] A method to replace IP addresses with geographical locations in traditional IP communication protocol messages:

[0032] After receiving a data packet from a network device, the IP translation interface first randomly assigns a geographical location information d(x, y, h) to the network device;

[0033] The geolocation communication server records the MAC address table m of the network devices and the MAC address table p of the IP translation interface, and establishes a forwarding table f(d, m, p).

[0034] After the location communication interface receives the data packet sent by the location communication device, the geographic location communication server records the location D (X, Y, H) of the location communication device and the MAC address M of the location communication device. At the same time, it establishes a forwarding table F (D, M, P) based on the MAC address P of the location communication interface.

[0035] Network devices and location communication devices use traditional table lookup forwarding methods to conduct data communication based on forwarding tables F1 and F2.

[0036] Since the forwarding table f already contains geographic location data d, the network device can be located using geographic location data d. Both the network device and the location communication device rely on data d in the forwarding table f for location determination. The geographic location communication server randomly assigns location information to the network devices connected to it based on its own location. Generally, one geographic location communication server is deployed in one building, with the network devices and the geographic location communication server in the same building. If the geographic location of the geographic location communication server is L(x, y, h), and if network device X1 is on the first floor, then network device X1 is assigned the geographic location L(x, y, z), where z is a random value between [h, h+1]. The location communication device directly obtains its location information using its own GPS. When it is necessary to confirm the location information of a device, the device's location can be determined through P in tables f and F.

[0037] In some cases, P1 in forwarding table F1 represents the port number of the IP translation interface, and P2 in forwarding table F2 represents the port number of the location communication interface.

[0038] Specifically, the IP translation interface and the location communication interface in the geolocation communication server are isolated from each other, meaning that all data packet forwarding must be processed by the geolocation communication server.

[0039] To conceal the true location information of the location communication device and improve the security of its communication, the location communication device and the traditional network device also communicate using a virtual location method.

[0040] The location communication server assigns a virtual location VD(X', Y', H') to the location communication device and establishes a mapping relationship R(VD, D) with the real location D(X, Y, H) of the corresponding location communication device.

[0041] The location communication server establishes a virtual forwarding table VF(VD, M, P);

[0042] After enabling the virtual position transformation function, the value of the virtual position VD changes randomly over time;

[0043] The location communication server uses a virtual forwarding table (VF) to participate in data communication with the geolocation communication server.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
