Description
Technical field
The present invention relates to authentication field, be specifically related to a kind of AUC and method for authenticating that authentication service is provided for unmanned plane.
Background technology
Unmanned plane Aerial photography, demonstration flight, take precautions against natural calamities recover, there is wide application in the field such as scientific investigation.Along with the develop rapidly of electronic technology, small-sized, MAV has had obvious breakthrough in Remote, cruising time, flight quality, becomes the General Aviation field focus of rising in recent years, is generally considered and has good development prospect.
Current unmanned plane has started to enter consumer level market, especially multi-rotor aerocraft, typically, as four axle multi-rotor aerocrafts have become in consumer level market the preferred unit being used for implementing to take photo by plane.
Along with the extensive use of unmanned plane particularly many rotor wing unmanned aerial vehicles, the communication security between unmanned plane and ground station has become the problem that unmanned plane exploitation producer and user are concerned about.Because unmanned plane market is promoted to consumer level by professional gradually, increasing ordinary consumer all can use unmanned plane to carry out taking photo by plane, play or the application such as model plane, and therefore the same area occurs that the situation of multiple UAVs is more and more general.Confirm that in order to enable unmanned plane which ground station is its legal effector, enable ground station ensure the unmanned plane controlled by it is UAV targets simultaneously, needs to set up a kind of unmanned plane and to communicate with ground station the method for authentication.
Communication security between unmanned plane and ground station is realized mainly by carrying out encipher-decipher method realization to the data in data transmission procedure in prior art, such as: the Chinese invention patent application that application number is 201410298318.2, denomination of invention is " a kind of unmanned plane based on the Big Dipper and 4G " discloses a kind of unmanned plane based on the Big Dipper and 4G, and this unmanned plane body is provided with master controller, dipper system global pick device, data encryption device, data processing equipment, camera of taking photo by plane, servomechanism and the first radio communication device; Also comprise ground base station, this ground base station is provided with the second radio communication device and data deciphering analytical equipment.The present invention, by setting data encryption device on unmanned plane, sends after high definition realtime graphic, audio frequency or the positioning information encryption of taking photo by plane, makes data safer.
In addition, application number is 201510002562.4, the Chinese invention patent application that denomination of invention is " for the many airborne equipments of unmanned plane with frequency enciphered digital communications control system " discloses a kind of for the many airborne equipments of unmanned plane same enciphered digital communications frequently control system, comprise airborne end control system and ground surface end control system, described airborne end control system comprises the first digital radio encrypted transmission module, described ground surface end control system comprises the second digital radio encrypted transmission module, the invention solves the equal unencryption of existing UAV Communication system, simple means is taked to intercept and capture or to disturb, the lighter causes ground control station cannot normally and UAV Communication, severe one loses the problem to UAV Flight Control power, improve unmanned plane air-ground dialogue fail safe and confidentiality.
But above-mentioned patent application did not all relate to unmanned plane and ground station before setting up Data-Link, how to confirm the solution whether communicating pair identity is legal, how to prevent illegal access or the illegal problem controlled.Current unmanned plane application adopts the point-to-point communication mode of single ground station control single rack unmanned plane mostly, ground station only relies on communications band, transmitting power and visual range to judge that whether unmanned plane is controlled, cannot solve the problem of multiple UAVs manipulation safety and over the horizon " relay " unmanned aerial vehicle (UAV) control within the scope of the same area transmitting power.
