S44: and the terminal sends a confirmation message to the key production center, wherein the confirmation message comprises the token carrying the expiration date.
On the basis of the foregoing embodiment, in the method of this embodiment, when the terminal sends the first request message to the key production center, the terminal further includes a token with a validity period in the first request message, so that the key production center generates a private key for the terminal in the validity period of the token, and sends the first authentication message to the terminal in the validity period of the token, and further, the terminal sends the confirmation message to the key production center in the validity period of the token.
In this embodiment, through adding the token mechanism, can further improve the security of message interaction in the shared unmanned aerial vehicle system of renting. Specifically, on one hand, the duration of the token validity period can be reasonably set, so that other people cannot attack the token within the token validity period. For example, the terminal may set a short validity period for the token according to the network state, so that others cannot perform network attack within the short 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, the first request message may be resent, so that the key production center redistributes the private key for the terminal.
