The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is to be expressly and implicitly understood by those of ordinary skill in the art that the described embodiments of the application can be combined with other embodiments without conflict.
The embodiment provides an intelligent door lock control method, which aims at solving the problem that the intelligent door lock with a temporary password function in the related art is high in safety risk.
Fig. 1 is a flowchart of an intelligent door lock control method according to an embodiment of the present application, and fig. 2 is a schematic diagram of an intelligent door lock control method according to an embodiment of the present application. Referring to fig. 1 and 2, the method includes steps S101 to S106.
Step S101, the client generates first information and uploads the first information to the server, wherein the first information comprises temporary password information. The temporary password corresponding to the temporary password information is randomly generated or manually input.
Step S102, the server receives the first information and encrypts the first information to obtain the second information.
Step S103, the server receives the unlocking request and issues second information to the corresponding door lock device.
Step S104, the door lock device decrypts the second information to obtain third information. It will be appreciated that the manner of encryption and decryption is not limited herein.
Step S105, the door lock device determines whether the input password to be processed is correct according to the third information, if yes, step S106 is executed, and if not, no operation is executed.
Step S106, unlocking the door lock device.
It should be noted that, the client may be a terminal device, such as a mobile phone, a tablet, a notebook, etc., where the corresponding program is installed, and the server may be a server, a processor, a cloud platform, etc., which are not limited herein, but in the process of executing the method, the server is matched with the client to be in communication connection, and the server is matched with the door lock device to be in communication connection.
In summary, the temporary password corresponding to the temporary password information is not obtained through a password book, and can be generated randomly or input manually, so that the possibility of being deduced through calculation is low, and the safety of the intelligent door lock can be improved; the temporary password information is stored in an encrypted form at the server side or is issued to the door lock device through the server side, so that the safety of the intelligent door lock can be further improved.
As an alternative embodiment, the first information is associated with a lock id, and correspondingly, the second information and the third information are also associated with a lock id. And for step S103, the unlocking request also carries a lock id, and the server may issue the second information associated with the lock id to the door lock device that uploads the unlocking request, so as to reduce the risk of issuing errors of the second information.
As an alternative embodiment, before step S101, the method further includes the client generating temporary cryptographic information, and this step may specifically include the following steps.
The client obtains the temporary password, which may be obtained by manually inputting the client or may be randomly generated by the client, and the temporary password is usually a combination of numbers, and of course, the temporary password may also be one or more combinations of letters, numbers and special symbols, where the keyboard of the door lock device allows, without limitation.
The client adopts a Hash algorithm to the temporary password to obtain a temporary password Hash value, and the temporary password information comprises the temporary password Hash value. It should be noted that, the temporary password is uploaded to the server by adopting the temporary password hash value, and the server only encrypts the first information, so that the server cannot know the temporary password through the temporary password information, thereby improving the security of the temporary password.
Through the technical scheme, the temporary password is subjected to hash processing at the client side and then encrypted at the server side, and can be transmitted to the door lock device, so that double guarantees are provided for the temporary password stored at the server side and sent to the door lock device from the server side, and the safety of the temporary password is further improved.
Further, the method may further include a step of processing a password to be processed, wherein the step of processing the password to be processed is performed via the door lock device and should be performed after the step S103 and before the step S104 is performed, and the step of processing the password to be processed may specifically include the following steps.
The door lock device acquires a password to be processed, and the password to be processed is manually input. It should be noted that, after the user determines the temporary password via the client, the user may be notified of the temporary password in an offline manner.
The door lock device adopts a Hash algorithm to the password to be processed to obtain a password Hash value to be processed, and if the temporary password Hash value is consistent with the password Hash value to be processed, the password to be processed is judged to be correct. It should be noted that the Hash algorithm used in this step is the same as that used in the temporary password in the related embodiment, so in the case that the temporary password Hash value is identical to the temporary password Hash value, the password to be processed is the same as the temporary password, i.e. the password to be processed is correct, otherwise, the password to be processed is incorrect.
According to the technical scheme, the processing of the password to be processed is performed in the door lock device, so that the risk that the password to be processed is tampered or the judgment result is tampered can be reduced, and the safety of the intelligent door lock is improved.
As an optional embodiment, for step S102, the first information further carries user information, where the user information includes an account, the server may determine its authority according to the account, and if the authority meets a preset requirement, allow the encryption operation to be performed and save the user information, and if the authority does not meet the preset requirement, prohibit the encryption operation to be performed and feed back to the client. The preset requirements are not limited herein and may be adjusted according to the actual situation.
As an alternative embodiment, for step S102, the first information may further include a validity period, which may be manually entered into the client, and which defines the lifetime of the temporary password. Correspondingly, the third information decrypted in step S104 also includes a validity period, and before executing step S106, the method may further include the following steps; the door lock device determines whether the input time of the password to be processed falls within the validity period included in the third information, if so, the execution of step S106 is permitted, and if not, the execution of step S106 is prohibited.
It will be appreciated that since step S105 is relatively complex, the above-described steps related to the validity period are preferentially performed after step S104 and before step S105, so as to reduce the probability of ineffective execution of step S105, thereby improving efficiency as a whole.
It should be noted that the first information includes a validity period, so the validity period is also in an encryption range, thereby reducing the risk of falsifying the validity period and improving the security of the intelligent door lock.
As an alternative embodiment, for step S102, the first information may also carry a validity period, i.e. the validity period does not participate in the encryption. Accordingly, the server may perform the following operations: in step S103, if the unlocking request carries the input time of the password to be processed, the server may determine whether the input time of the password to be processed falls within the validity period after receiving the unlocking request, if yes, the second information is issued to the corresponding door lock device in step S103, and if not, the second information is prohibited from being issued to the corresponding door lock device in step S103. Or the server side can also perform a self-checking function to automatically delete the second information exceeding the validity period so as to omit the subsequent related steps.
For step S102, the second information may further include a signature, where the second signature is signed with a server private key. Accordingly, if the signature is also included in the third information decrypted in step S104, the method may further include the following steps before executing step S106; the door lock device determines whether the signature included in the third information is correct, and if so, allows execution of step S106, and if not, prohibits execution of step S106.
It will be appreciated that since step S105 is relatively complex, the above-described steps related to signature are preferably performed after step S104 and before step S105, so as to reduce the probability of ineffective execution of step S105, thereby improving efficiency as a whole.
Through the technical scheme, the door lock device can determine whether the second information is from the server through the signature, so that the second information from other sources is avoided, the second information is ensured to be correct in source, and the second information comprises the signature, so that the signature is also in an encryption range, the risk of the signature being tampered is reduced, and the safety of the intelligent door lock is improved.
It should be noted here that in this method, the preconditions of step S106 can only be fulfilled if they are all fulfilled.
As an alternative embodiment, since the method adopts one intelligent door lock to correspond to one secret key, the overall security can be improved, but the security of the secret key is reduced along with the use time, and the method can further comprise the following steps.
The server receives the reset signal uploaded by the client or the door lock device. It should be noted that, in the case of uploading a reset signal by the client, the reset signal may be generated periodically or triggered manually; in the case of uploading the reset signal by the door lock device, the reset signal may be generated after the door lock device is opened according to the password to be processed, or may be triggered manually.
The server replaces the encryption key according to the reset signal, and sends the decryption key corresponding to the replaced encryption key to the door lock device, and the door lock device cooperates with the replacement of the decryption key.
Through this technical scheme, can realize the change of secret key to improve holistic security. It should be noted that, for the replacement of the key, the door lock device may also be executed, that is, the door lock device acquires a reset signal, and replaces the decryption key in response to the reset signal, and uploads the encryption key corresponding to the replaced decryption key to the server, where the server cooperates to execute the replacement of the encryption key.
As an alternative embodiment, due to the low frequency of temporary password use, the door lock device side disconnects the communication connection with the service side and goes to sleep in case the door lock device experiences a preset period after opening or a preset period after establishing a communication connection with the service side or a preset period after the completion of the input of the password to be processed, due to power consumption
It can be understood that the above preset time periods should be different, and in particular, the time period may be determined according to practical situations, and by using the technical scheme, the components of the door lock device that operate may be reduced, so as to achieve low power consumption.
Further, before step S103, the method may further include the steps of: after the door lock device acquires the password to be processed, the door lock device is awakened and establishes communication connection with the server. It will be appreciated that the components of the door lock device that are awakened include: means for performing communication connection with the server, means for performing step S105, means for performing step S106, and the like.
Further, in the case where the password to be processed is the same as the fixed password, only the means for performing step S106 may be awakened, but the means for performing step S105 is not awakened, so that the door lock apparatus is disconnected from the service side communication; in the case where the password to be processed is different from the fixed password, the means for performing communication connection with the server may be awakened, the means for performing step S105, and the means for performing step S106 may be awakened to establish communication connection between the door lock apparatus and the server. By the technical scheme, the power consumption is further reduced.
As an alternative embodiment, after performing step S106, the method may further include the steps of: the door lock device uploads a successful unlocking signal to the server; the server side responds to the unlocking success signal to generate and store a corresponding history record. Wherein the history record includes: information such as lock id, unlocking time, etc. Through the technical scheme, the server side stores the history record so as to be convenient for users to review. The server may also notify the client in response to the unlock success signal. Correspondingly, under the condition of unlocking failure, the server side can also cooperate to generate a corresponding history record and inform the client side.
