[0094] The technical solutions of the present invention will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0095] FIG. 1 is an architectural diagram of a rental system for shared drones provided by the present invention. As shown in FIG. 1, the drone rental system includes: a terminal, a drone management platform, and a key production center. Among them, the terminal is the terminal equipment used by the user, which includes, but is not limited to, mobile phones, tablet computers, laptops and other electronic equipment; the drone management platform is the drone management server, which can receive the drone rental request from the terminal and send it to The terminal provides information about the right to rent the drone. The key production center can be a key management server, which is used to manage the public and private keys of all terminals.

[0096] In the prior art, when a user uses a shared drone, he can log in to the drone management platform through the user terminal APP, scan the QR code, etc., and then enter the personal information and rental information, and the drone management The platform returns the lease information of the shared drone to the user. However, in the aforementioned shared drone rental process, the security of the interactive information between the user terminal and the drone management platform cannot be guaranteed, and there is a possibility of being attacked.

[0097] As shown in Figure 1, the shared drone rental system provided by the present invention adds the public key and private key used by the key production center to manage the terminal, so that the drone management platform uses a public key pair. The man-machine rental right message is encrypted, and the terminal uses the private key to decrypt the UAV rental right message, and a secure information exchange channel is constructed between the terminal and the UAV management platform to ensure the security of the exchange information.

[0098] FIG. 2 is a flowchart of Embodiment 1 of a method for renting a shared drone provided by the present invention, and the execution subject of this embodiment may be the terminal in FIG. 1. As shown in Figure 2, the method of this embodiment includes:

[0099] S21: Send a first request message to the key production center, where the first request message includes the identity of the terminal.

[0100] S22: Receive a first authentication message sent by a key production center, where the first authentication message includes a private key, and the private key is performed by the key production center using preset parameters and the terminal's identity. Calculated.

[0101] Specifically, before obtaining the lease right of the shared drone, the terminal needs to first obtain the private key from the key production center through the first request message. Among them, the key production center can be a trusted third party, and the key production center can use preset parameters and preset algorithms to perform calculations based on the identity provided by the terminal to obtain the private key of the terminal, and pass the first authentication

The certificate message is sent to the terminal, where the preset parameters can be generated according to a preset algorithm during the initialization phase of the key production center.

[0102] Wherein, the timing for the terminal to send the first request message to the key production center is not specifically limited, and it can be performed at any time before acquiring the lease right of the shared drone. In an optional implementation manner, the terminal sends the first request message to the key production center when registering on the drone management platform. In another alternative embodiment, after the terminal obtains the drone lease right message sent by the drone management platform, and finds that the message is an encrypted message and does not have a corresponding decryption private key, it sends the first message to the key production center. A request message to request the private key.

[0103] Optionally, the identity of the terminal is any string of meaningful characters, including but not limited to: the user's emai 1 address, mobile phone number, identity number, etc.

[01041 S23: Send a second request message to the drone management platform, where the second request message includes the identity of the terminal, and the second message is used to instruct the drone management platform according to the identity of the terminal And the preset parameter generates a public key for the terminal.

[0105] Specifically, the identity-based encryption scheme is used in this embodiment, and the identity-based encryption scheme uses asymmetric encryption technology. Taking the communication process between the sender A and the receiver B as an example, the sender A uses the receiver Bs The public key encrypts the plaintext to obtain the ciphertext. After receiving the ciphertext, the recipient B uses the private key of the recipient B to decrypt the ciphertext to obtain the plaintext. Therefore, in this embodiment, the terminal sends a second request message to the drone management platform, which includes the identity of the terminal, so that the drone management platform can obtain the public key corresponding to the terminal according to the identity of the terminal, so that no one The drone management platform can encrypt the UAV lease message according to the public key of the terminal.

[0109] S25: Use the private key to decrypt the drone lease right message to obtain the drone lease right.

[0110] After the drone management platform allocates the drone lease right to the terminal, it uses the public key to encrypt the drone lease right message and sends it to the terminal, and the terminal uses the private key to decrypt the drone lease right message, thereby Obtain the right to rent the drone. Since only the terminal has the private key, others cannot attack the drone rental rights message, ensuring the security of message interaction in the rental system of shared drones.

[0111] In this embodiment, the terminal sends a first request message to the key production center, the first request message includes the terminal's identity, so that the key production center generates a private key for the terminal; By sending a second request message to the drone management platform, the second request message includes the identity of the terminal, so that the drone management platform can generate a public key for the terminal; and the drone management platform uses The public key encrypts the drone lease message,

The terminal uses the private key to decrypt the drone lease message and obtain the drone lease right. Through the above process, the security of messages between the UAV management platform and the terminal is ensured, and attacks from the outside world are avoided.

[0114] S31: The terminal sends a first request message to the key production center, where the first request message includes the identity of the terminal.

[0115] S32: The key production center uses the preset parameters and the terminal's identity to perform operations to generate a private key for the terminal.

[0116] S33: The key production center sends a first authentication message to the terminal, where the first authentication message includes the private key.

[0117] S34: The terminal sends a second request message to the drone management platform, where the second request message includes the identity of the terminal.

[0118] S35: The drone management platform generates a public key for the terminal according to preset parameters and the identity of the terminal.

[0119] S36: The drone management platform uses the public key to encrypt the drone lease right message.

[0120] S37: The drone management platform sends a drone lease right message to the terminal.

[0121] S38: The terminal uses the private key to decrypt the drone lease right message to obtain the drone lease right.

[0122] For the specific implementation process of this embodiment, reference may be made to the detailed description of the first embodiment above, which will not be repeated here.

[0123] In addition, it should be noted that this embodiment exemplifies the message interaction process in the rental system for shared drones in one of the scenarios.

Through the above process, the security of messages between the UAV management platform and the terminal is ensured, and attacks from the outside world are avoided.

[0127] FIG. 4A is a flowchart of Embodiment 3 of the method for renting a shared drone provided by the present invention, and FIG. 4B is a signaling flowchart of Embodiment 3 of the method for renting a shared drone provided by the present invention. Based on the example, this embodiment describes the process of obtaining the private key by the terminal in more detail.

[0128] As shown in FIG. 4A and FIG. 4B, the method of this embodiment includes:

[0129] S41: The terminal sends a first request message to the key production center, where the first request message includes the identity of the terminal and a token carrying a validity period.

[0130] S42: During the validity period of the token, the key production center uses preset parameters and the terminal's identity to perform operations to generate a private key for the terminal.

[0131] S43: The key production center sends a first authentication message to the terminal, where the first authentication message includes the

The private key and the token carrying the validity period.

[0132] S44: The terminal sends a confirmation message to the key production center, where the confirmation message includes the token carrying the validity period.

[0134] In this embodiment, by adding a token mechanism, the security of message interaction in the shared drone rental system can be further improved. Specifically, on the one hand, by reasonably setting the duration of the token validity period, others cannot attack during the token validity period. For example, the terminal can set a shorter validity period for the token according to the network status, so that others cannot conduct network attacks within the shorter validity period. On the other hand, the terminal and the key production center can also determine the security of the network according to the validity period of the token. For example, if the terminal does not receive the corresponding first authentication message within the validity period of the token after sending the first request message, it can resend the first request message so that the key production center can redistribute the private key for the terminal.
