In the embodiment of the invention, the unmanned aerial vehicle and the user terminal firstly generate an encryption key and a public key of the unmanned aerial vehicle based on the identity of the unmanned aerial vehicle by the intelligent base under the supervision and support of the intelligent base, and generate a decryption key and a public key of the unmanned aerial vehicle based on the identity of the user terminal. Then, the unmanned aerial vehicle encrypts data to be transmitted of the unmanned aerial vehicle based on an encryption key of the unmanned aerial vehicle and a public key of the user terminal, and the user terminal decrypts the encrypted data to be transmitted based on a decryption key of the unmanned aerial vehicle and the public key of the unmanned aerial vehicle. Because the encrypted data to be transmitted contains the identity of the unmanned aerial vehicle and the identity of the user terminal, when the identities of the corresponding user terminals are matched, the encrypted data to be transmitted can be correctly decrypted, so that complex signature generation and verification processes are avoided, the calculated amount of data encryption and decryption is reduced, and the method is suitable for the unmanned aerial vehicle.
Some embodiments provide a method for securely sharing data of an unmanned aerial vehicle, which is used for encrypting data and transmitting the encrypted data to a user terminal when the unmanned aerial vehicle sends the data to the user terminal, and the user terminal can acquire the data after decrypting the encrypted data, so that the security of data transmission between the unmanned aerial vehicle and the user terminal is ensured. Referring to fig. 1, the unmanned aerial vehicle data security sharing method relates to three devices, namely an unmanned aerial vehicle 10, a user terminal 20 and an intelligent base 30, which are respectively described in detail below.
The drone 10 is configured to perform free movement within a user-specified flight zone and to collect data within the flight zone and to enable management within the flight zone.
The user terminal 20 is typically held by the user, for example, the user terminal 20 is a smart phone of the user, which is used for data transmission with the unmanned aerial vehicle, for example, to acquire data collected by the unmanned aerial vehicle, or to send control signals to the unmanned aerial vehicle.
The intelligent base 30 is used for being placed in a flight area of the unmanned aerial vehicle, managing the unmanned aerial vehicle, providing services such as charging, management and maintenance for the unmanned aerial vehicle, and controlling actions such as automatic return and automatic cruising of the unmanned aerial vehicle. For example, the smart dock 30 generates an encryption key and a public key for the drone based on the identity of the drone and issues the drone's encryption key to the drone. For the ue 20 that the ue needs to send data, the intelligent base 30 generates a decryption key of the ue and a public key of the ue 20 based on the identity of the ue 20, and sends the decryption key of the ue to the ue 20.
When the flight area designated by the user is an indoor scene, such as a home, an office, a factory building, etc., a plurality of indoor micro-robots can be arranged indoors for indoor data collection and indoor management, and an intelligent base 30 can be placed indoors for unmanned aerial vehicle management, and services such as charging, management and maintenance are provided for the unmanned aerial vehicle. When the first user terminal needs to acquire the acquired data of the unmanned aerial vehicle, the unmanned aerial vehicle can encrypt the data according to the encryption key of the unmanned aerial vehicle, the identity of the first user terminal and the public key, and the first user terminal can decrypt the data according to the decryption key of the unmanned aerial vehicle, the identity of the unmanned aerial vehicle and the public key. Similarly, when the second user terminal needs to acquire the acquired data of the unmanned aerial vehicle, the unmanned aerial vehicle can encrypt the data according to the encryption key of the unmanned aerial vehicle, the identity of the second user terminal and the public key, and the second user terminal can decrypt the data according to the decryption key of the unmanned aerial vehicle, the identity of the unmanned aerial vehicle and the public key, so that the safety of data transmission between the unmanned aerial vehicle and the user terminal is ensured.
Referring to fig. 2 and fig. 3, the following specifically describes an implementation process of the unmanned aerial vehicle data security sharing method.
Step 100: the intelligent base constructs initial information, wherein the initial information comprises system public parameters and a system master key, and the system public parameters are used for being disclosed to the unmanned aerial vehicle and the user terminal.
In some embodiments, the system public parameters and system master key are used to subsequently generate encryption keys, decryption keys, and drone and user terminal public keys, so that the initial information needs to be constructed by the smart base. And when constructing initial information, it is also necessary to ensure that it is based on the randomness of the intelligent base, so the intelligent base needs to acquire some random numbers through a random algorithm. In some embodiments, the intelligent base first selects two random integers r, s, i.eThen constructing prime number p-order cyclic group G 1 And G 2 And set up a cyclic group G 1 Is a generator g. Then constructing a bilinear mapping function e, and defining the bilinear mapping function e as: g 1 ×G 1 →G 2 I.e. two cyclic groups G 1 The elements in (a) are mapped into cyclic group G 2 Is a component of the group. Then reconstruct the hash function H 1 、H 2 And H 3 Wherein the hash function H 1 And a hash function H 2 Are all used for connecting any lengthThe bit string is mapped to cyclic group G 1 Of the element, hash function H 3 For circulating group G 2 The elements of (a) are mapped into bit strings of a preset length. Then a padding function Ω is constructed for padding bit strings of arbitrary length into bit strings of the preset length. Finally, the intelligent base calculates Q=g firstly r Then the intelligent base discloses a system public parameter params= (G) to the unmanned aerial vehicle and the user terminal 1 ,G 2 ,g,e,Q,H 1 ,H 2 ,H 3 Ω), and secretly holds the system master key msk= (r, s). In this embodiment, the group G is cycled through 1 And G 2 Bilinear mapping function e, hash function H 1 、H 2 And H 3 The relation of the mutual association between the functions omega is filled, so that the method can be used for encryption calculation and decryption calculation in the subsequent data transmission.
Step 200: the intelligent base acquires the identity u of the unmanned aerial vehicle and calculates an encryption key EK of the unmanned aerial vehicle at least according to the system public parameter, the system master key and the identity u of the unmanned aerial vehicle u And public key psk of unmanned aerial vehicle u And the encryption key EK of the unmanned aerial vehicle is used for u Transmitting to the unmanned aerial vehicle and disclosing the public key psk of the unmanned aerial vehicle to a user terminal u 。
In some embodiments, each unmanned aerial vehicle has its own identity u when it is deployed, so that it is necessary for each unmanned aerial vehicle to calculate the encryption key EK of that unmanned aerial vehicle based on its identity u and from the system public parameters and the system master key u And its own public key psk u . Wherein the encryption key EK of the unmanned aerial vehicle u For encryption of data when the drone sends the data, so that it is sent to the drone, while the public key psk of the drone u For assisting in decrypting the encrypted data and thus requires disclosure to the user terminal. In some embodiments, the intelligent chassis first calculates an encryption key component:
subsequent acquisition of random numbersAnd->And calculating:
