After each unlocking, a new locking code can be generated based on the working key stored in the lockset and based on an agreed generation algorithm, and the dynamic updating of the locking code is realized under the condition that the working key is not changed. The generation rule of the working key can be uniquely stored for the service system, so that the safe connection and dynamic control of the service system and the lock are realized.
According to an embodiment of the present disclosure, the money box management method may further include a method of initializing the device, for example, including the step of generating an initial lock code, which is stored in the business system and the lock.
Fig. 6 schematically illustrates a flow chart of a method of generating an initial lock code according to an embodiment of the present disclosure.
As shown in fig. 6, the money box management method of this embodiment includes operations S610 to S670.
In operation S610, the business system obtains a lock list based on the internet of things management platform, where the lock list is matched with the money box, and the lock list includes a lock identifier corresponding to a lock.
According to the embodiment of the disclosure, before the business system obtains the lock list, a step of money box registration can be further included. The cash box may be an active cash box, which may contain a unique device identification at the time of shipment, e.g., may contain a device SN number. When a money box is newly added, whether the money box is registered to the Internet of things management platform or not can be selected in the service system, and a registration application is initiated to the Internet of things management platform based on the equipment identifier. The management platform of the internet of things can feed back the registration result to the service system. It can be understood that one or more internet of things management platforms can be connected based on the complexity requirement of the service system device management, and correspondingly, the registration result can include an internet of things management platform identifier, so that the online state of the money box can be updated in real time by the service system after registration.
According to the embodiment of the disclosure, after the money box is registered, a money box activation step may be included, specifically, a manager may perform an activation operation on the money box, for example, continuously pressing an on-off key three times, the money box initiates an activation request like an internet of things management platform, so that the money box is activated on the internet of things management platform. It can be understood that the activation request may include a money box identifier and a service system identifier, so that a unique mapping relationship among the service system, the internet of things management platform, and the money box may be established, and the fine management of the money box may be realized. The management platform of the internet of things can feed back the money box activation result to the money box. In some specific embodiments, the money box may be a money box that has been registered in the management platform of the internet of things, for example, when the money box is returned to a factory for maintenance, and the money box is called inside an organization, and the lock matched with the money box may be a lock that has been assigned with a lock identifier (for example, a lock ID) by the business system, and when the money box is managed by the business system again, the money box registration and activation need to be performed again for safety reasons, but the lock identifier may not need to be changed. Therefore, after the money box receives the activation result feedback, the lock interface can be automatically called to acquire the lock identification. One cash box can be matched with one or more locksets, and correspondingly, one or more lockset identifications can be obtained and a lockset list can be generated. Further, the money box can send the lock list to the business system through the internet of things management platform, and therefore connectivity of the lock and the business system is established. It can be understood that, in order to ensure acquisition of a lock list and prevent a failure of an automatic lock calling interface of a cash box, a business system may initiate a lock list acquisition request after successful activation of a device, the request may be sent to the cash box through an internet of things management platform, and the cash box may initiate a call to a lock.
In operation S620, the lock acquires first encrypted data from the service system based on the internet of things management platform to generate a first communication key and second encrypted data.

The tool key can be written into the lockset encryption chip. The generation rule of the communication key can be simpler and is disposable so as to reduce the load of the computer.
In embodiments of the present disclosure, the encryption device may generate the first encrypted data based on a preset encryption algorithm, for example, an asymmetric encryption algorithm, and in some specific embodiments, the first encrypted data may include public key data including a signature. After the service system acquires the public key data containing the signature, the public key data containing the signature can be issued to the lockset through the internet of things management platform. The lockset can analyze the first encrypted data and generate a first communication key and second encrypted data based on the analyzed data. And analyzing the public key data containing the signature, wherein the analyzing comprises verifying the signature of the public key data containing the signature. Correspondingly, the analytic data can be public key data obtained after signature verification. The generating of the first communication key may include generating security data, such as a random number, that the lock generates based on a cryptographic technique and that can be used to communicate with the business system. The lockset can utilize a random number to generate a first communication key according to an agreed algorithm, wherein the agreed algorithm can be a common algorithm for generating the communication key agreed by a lockset manufacturer and an organization, and the same communication key can be generated at a lockset end and a business system end through the agreed algorithm so as to establish the connectivity of the lockset and the business system. The type of the contract algorithm may include a symmetric encryption algorithm, an asymmetric encryption algorithm, and a hash algorithm, and may be, for example, the cryptographic algorithms SM2, SM3, and SM 4. The second encrypted data may be data obtained by encrypting the security data by using the analysis data after the lock generates the security data that can be used for communicating with the service system based on a cryptographic technique. For example, the second encrypted data may be obtained by encrypting a random number generated by the lock with a public key obtained after the signature verification.
According to an embodiment of the present disclosure, when the lock list is empty, the method further includes: the business system automatically generates a lock identification. And the business system sends the lock identification and the first encrypted data to the lock together based on an Internet of things management platform.

In the embodiment of the disclosure, when the money box and the lock matched with the money box are not registered in the internet of things management platform and are connected with the business system, the lock identification obtained by calling the lock interface by the money box can be null, so that an empty lock list is obtained. At this moment, a lock identification can be automatically generated by the business system, and the lock identification and the first encrypted data are jointly sent to the lock through the internet of things management platform. The lockset stores the lockset identification, for example, the lockset identification can be written into an encryption chip carried by the lockset to be used as the unique identification of the lockset.
In operation S630, the service system obtains second encrypted data from the lock based on the internet of things management platform.
In operation S640, the encryption device generates a second communication key and a lock operation key based on second encryption data from the service system, wherein the first communication key and the second communication key are the same.

The lock encryption factor can be stored for the business system and used as a calculation factor for generating the working key. In some specific embodiments, the lock encryption factor may include the second encrypted data, further may include a lock identifier, and further may include a security factor such as a current system timestamp. Further, the encryption device may generate a second communication key and a lock operation key based on the lock encryption factor from the business system. The algorithm of the second communication key is the same as that of the first communication key, and the generated first communication key is the same as that of the second communication key, so that the connectivity of the lockset and the service system can be established. For example, the encryption device may decrypt the second encrypted data to obtain the secure data, e.g., a random number, and then generate the second communication key based on the random number. Further, the encryption device may generate a lock operation key based on the lock identification in the lock encryption factor and a security factor (e.g., a timestamp). Based on the requirement of data storage overhead, the business system can save the lock encryption factor without saving the lock working key.
