[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0030] Figure 1 is one of the flow schematic diagrams of the flight safety management method provided by the present application, which is applied to a management center, as shown in Figure 1 The method comprises the following steps.

[0031] Step S1, receiving preset sensitive information reported by a low-altitude aircraft; wherein the low-altitude aircraft carries a first token, a first product identification code of the low-altitude aircraft and a first token expiration time when reporting the preset sensitive information.

[0032] The management center receives the preset sensitive information reported by the low-altitude aircraft. The content of the preset sensitive information can be any information agreed upon in advance by the low-altitude aircraft and the management center. The low-altitude aircraft carries a first token, a first product identification code of the low-altitude aircraft and a first token expiration time when reporting the preset sensitive information. The first token and the first token expiration time are obtained in advance by the low-altitude aircraft from the management center. The first product identification code is the unique identification of the low-altitude aircraft, and different low-altitude aircrafts have different first product identification codes. The first token expiration time is used to limit the time limit of the first token.

[0033] Step S2, in response to the first token expiration time being less than the current time, obtaining a first public key corresponding to the first product identification code, performing first token verification on the first token by using the first public key, and in response to the first token verification passing, sending confirmation receiving information of the preset sensitive information to the low-altitude aircraft.

[0034] If the first token expiration time is less than the current time, it indicates that the first token is not expired, and the first product identification code corresponding to the first public key is obtained according to the pre-associated stored data, the first token is verified by using the first public key, and if the first token verification is passed, it is confirmed that the preset sensitive information is legal and effective, and the confirmation receiving information of the preset sensitive information is sent to the low-altitude aircraft, and the preset sensitive information can be further processed.

[0035] It can be understood that the first token verification can also be performed first, and then it is confirmed whether the first token expiration time is less than the current time after the first token verification. First, it is beneficial to improve the processing efficiency to execute whether the first token expiration time is less than the current time.

[0038] The first token is a hash value generated by using the first product identification code and the first token expiration time, and the result after signing by using the first private key. When the first token is verified by using the first public key, the signature verification of the first token is performed by using the first public key to obtain a first digest, and a first hash value is generated by using the first product identification code and the first token expiration time; if the first hash value is consistent with the first digest, the first token verification is passed; if the first hash value is inconsistent with the first digest, the first token verification is not passed.

[0039] The flight safety management method provided by the application improves the accuracy of the first token verification, thereby further improving the safety of low-altitude flight.

[0046] If the low-altitude controller wants to control the low-altitude aircraft, the low-altitude controller needs to apply for a second token to the control center first. The control center receives the second token application request sent by the low-altitude controller, and the second token application request includes second identity information of the low-altitude controller, and the second identity information includes a second product identification code of the low-altitude controller.

The second token expiration time can be sent in the form of base64 encoding. If the second token expires, the low-altitude controller needs to apply for a new second token.

[0049] The flight safety control method provided by the application receives the second token application request sent by the low-altitude controller, wherein the second token application request includes second identity information of the low-altitude controller, and the second identity information includes a second product identification code of the low-altitude controller, in response to confirming that the second identity information is legal, a second key pair is generated, and the second key pair is stored in correspondence with the second product identification code, wherein the second key pair includes a second public key and a second private key, a second digest is generated by applying a hash function to the set second token expiration time and the second product identification code, the second digest is signed with the second private key, the signed information is taken as the second token, the second token expiration time is stored in correspondence with the second product identification code, the second token and the second token expiration time are sent to the low-altitude controller, the security of the second token is improved, and the safety of the low-altitude flight is further improved.

The content of the preset sensitive information can be any information agreed in advance by the low-altitude aircraft and the management center. The low-altitude aircraft carries the first token, the first product identification code of the low-altitude aircraft and the expiration time of the first token when reporting the preset sensitive information. The first token and the expiration time of the first token are acquired in advance by the low-altitude aircraft from the management center. The first product identification code is the unique identification of the low-altitude aircraft, and different low-altitude aircrafts have different first product identification codes.

[0064] The first token is a result of generating a hash value for the first product identification code and the first token expiration time and signing the result with the first private key. In the first token verification with the first public key, the first token is checked for signature, a first digest is obtained, a first hash value is generated for the first product identification code and the first token expiration time, and if the first hash value is consistent with the first digest, the first token verification is passed; if the first hash value is inconsistent with the first digest, the first token verification is failed.

In addition, the first identity information can also contain other agreed contents, such as the name of the holder of the low-altitude aircraft, the holder's identity card number, the holder's occupation, the application flight area, the flight purpose, other flight information, etc.

[0068] The management center checks the first identity information, and if it is confirmed that the first identity information is legal, a first key pair is generated, the first key pair comprising a first public key and a first private key, and the first key pair is stored corresponding to the first product identification code.

[0069] The management center sets a reasonable first token expiration time according to the information of the holder of the low-altitude aircraft, the flight purpose, the application flight area, etc., generates a first digest by applying a hash function to the set first token expiration time and the first product identification code, signs the first digest with a first private key, takes the signed information as a first token, and sends the first token and the first token expiration time to the low-altitude aircraft. The first token expiration time can be sent in the form of base64 encoding. The low-altitude aircraft receives and stores the first token and the first token expiration time sent by the management center. If the first token expires, the low-altitude aircraft needs to reapply for the first token.

[0070] The flight safety management method provided by the application sends a first token application request to the management center, wherein the first token application request includes first identity information of the low-altitude aircraft, and the first identity information includes a first product identification code of the low-altitude aircraft; receives the first token and the first token expiration time sent by the management center, wherein the first token and the first token expiration time are sent by the management center in response to confirming that the first identity information is legal, generating a first key pair, storing the first key pair corresponding to the first product identification code, applying a hash function to the set first token expiration time and the first product identification code to generate a first digest, signing the first digest with a first private key, and taking the signed information as a first token.

[0072] The second public key and the second token expiration time are generated and set according to the second token acquisition request sent by the low-altitude controller and received by the management center.

[0073] If the low-altitude controller wants to control the low-altitude aircraft, it needs to apply for a second token to the management and control center first. The low-altitude controller sends a second token acquisition request to the management and control center. The management and control center receives the second token application request sent by the low-altitude controller, and the second token application request includes the second identity information of the low-altitude controller. The second identity information includes the second product identification code of the low-altitude controller. The second product identification code is the unique identifier of the low-altitude controller, and the second product identification codes of different low-altitude controllers are different. In addition, the second identity information can also include other agreed contents, such as the name of the holder of the low-altitude controller, the holder's identity card number, the holder's occupation, the application flight area, the flight purpose, and other flight information.

[0074] The management and control center verifies the second identity information, and in response to confirming that the second identity information is legal, generates a second key pair, which includes a second public key and a second private key, and stores the second key pair corresponding to the second product identification code.

[0075] The management and control center sets a reasonable second token expiration time according to the holder information of the low-altitude controller, the flight purpose, the application flight area, etc. The second token expiration time and the second product identification code are applied to a hash function to generate a second digest. The second digest is signed with the second private key, and the signed information is used as the second token. The second token and the second token expiration time are sent to the low-altitude controller. The second token expiration time can be sent in the form of base64 encoding. If the second token expires, the low-altitude controller needs to reapply for a second token.

[0076] The low-altitude aircraft needs to apply to the management and control center for the second public key of the low-altitude controller that can be received in the flight area, which is used to verify the second token. If multiple low-altitude controllers' control instructions are needed, the second public keys of multiple low-altitude controllers can be applied to the management and control center.

[0077] The low-altitude aircraft sends a second public key acquisition request to the management and control center. The management and control center receives the second public key acquisition request sent by the low-altitude aircraft. The second public key acquisition request includes the second product identification code of at least one low-altitude controller. The low-altitude aircraft sends the second public key acquisition request with the first token, the first product identification code of the low-altitude aircraft, and the first token expiration time.

[0078] After confirming that the first token expiration time is less than the current time, the management and control center obtains the first public key corresponding to the first product identification code, performs first token verification on the first token using the first public key, and if the first token verification is passed, obtains the second public key and the second token expiration time corresponding to the second product identification code of at least one low-altitude controller and sends them to the low-altitude aircraft. The low-altitude aircraft receives the second public key and the second token expiration time corresponding to the second product identification code of at least one low-altitude controller.

[0079] It can be understood that the first token verification can be performed first, and whether the first token expiration time is less than the current time is confirmed after the first token verification. First, whether the first token expiration time is less than the current time is executed to improve processing efficiency. If the first token expiration time is not less than the current time, the first token verification is not performed. If the first token expiration time is less than the current time, but the first token verification fails, the management center will not send the second token and the second token expiration time to the low-altitude aircraft.

[0080] The flight safety management method provided by the application, by sending a second public key acquisition request to the management center;Wherein, the second product identification code of at least one low-altitude controller is included in the second public key acquisition request, the low-altitude aircraft sends the second public key acquisition request carrying the first token, the first product identification code of the low-altitude aircraft and the first token expiration time;At least one low-altitude controller's second product identification code corresponding second public key and second token expiration time sent by the management center are received;Wherein, the second public key and the second token expiration time are obtained by the management center in response to the first token expiration time being less than the current time, the first public key corresponding to the first product identification code is obtained, the first token is verified by the first token, and in response to the first token verification, the second public key corresponding to at least one low-altitude controller is obtained according to the second product identification code, which improves the security of the second public key acquisition request of the low-altitude aircraft, thereby further improving the communication security of the low-altitude aircraft.

[0081] According to the flight safety management method provided by the application, after receiving the second public key and the second token expiration time corresponding to the second product identification code of at least one low-altitude controller sent by the management center, the method further comprises: storing the second public key and the second token expiration time corresponding to the second product identification code in the preset password device respectively.

[0082] After receiving the second public key and the second token expiration time corresponding to the second product identification code of at least one low-altitude controller sent by the management center, the low-altitude aircraft can store the second public key and the second token expiration time corresponding to the second product identification code in the built-in preset password device, so as to improve the storage security of the second public key and the second token expiration time. Wherein, the preset password device supports universal format key. In this way, the low-altitude aircraft can import multiple second public keys according to the capacity of the password device, and can directly verify the second token without the help of a third party, thereby improving the efficiency of verifying the identity of the low-altitude controller.

[0083] The flight safety management method provided by the application, by storing the second public key and the second token expiration time corresponding to the second product identification code in the preset password device, improves the storage security of the second public key and the second token expiration time.

[0084] According to the flight safety management method provided by the application, after receiving the second public key and the second token expiration time corresponding to the second product identification code of the at least one low-altitude controller sent by the management center, the method further comprises: receiving the control instruction sent by the low-altitude controller; wherein the low-altitude controller carries the second token, the second product identification code of the low-altitude controller and the second token expiration time when sending the control instruction; in response to the second token expiration time being less than the current time, the second public key corresponding to the low-altitude controller is obtained according to the second product identification code, the second token is verified by using the second public key, and in response to the second token verification being passed, the control instruction is executed.

[0085] The low-altitude controller carries the second token, the second product identification code of the low-altitude controller and the second token expiration time when sending the control instruction. If the low-altitude aircraft confirms that the second token expiration time is less than the current time, the second public key corresponding to the low-altitude controller is obtained according to the second product identification code, the second token is verified by using the second public key, and if the second token verification is passed, the control instruction sent by the low-altitude controller is executed. If the low-altitude aircraft confirms that the second token expiration time is greater than the current time, or if the second token expiration time is less than the current time but the second token verification is not passed, the control instruction sent by the low-altitude controller is not executed.

[0086] It can be understood that the second token verification can be performed first, and then it is confirmed whether the second token expiration time is less than the current time after the second token verification. First determining whether the second token expiration time is less than the current time is beneficial to improve the processing efficiency.

[0087] The flight safety management method provided by the application receives the control instruction sent by the low-altitude controller, wherein the low-altitude controller carries the second token, the second product identification code of the low-altitude controller and the second token expiration time when sending the control instruction; in response to the second token expiration time being less than the current time, the second public key corresponding to the low-altitude controller is obtained according to the second product identification code, the second token is verified by using the second public key, and in response to the second token verification being passed, the control instruction is executed, which improves the judgment ability of the safety of the control instruction sent by the low-altitude controller, can effectively avoid the illegal intrusion of the low-altitude controller to the low-altitude aircraft, and further improves the safety of the low-altitude flight.

[0089] The second token is the result of signing a hash value generated from the second product identification code and the second token's expiration time using the second private key. When verifying the second token using the second public key, the second token is signed and verified using the second public key to obtain a second digest. A second hash value is then generated using the second product identification code and the second token's expiration time. If the second hash value matches the second digest, the second token verification is successful; otherwise, the second token verification fails.

[0090] The flight safety management method provided by this invention uses a second public key to sign and verify a second token to obtain a second digest. A second hash value is generated using a second product identification code and the expiration time of the second token. If the second hash value matches the second digest, the second token verification is successful; otherwise, the second token verification fails. This improves the accuracy of the second token verification, thereby further enhancing the safety of low-altitude flight.
