Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
The embodiment of the application provides an authority judgment method of an intelligent door lock, which is applied to a processor of the intelligent door lock, so that the intelligent door lock can timely know whether a door card has unlocking authority or not with low power consumption.
Referring to fig. 1, the method for determining the authority mainly includes the following steps:
s101, obtaining an unlocking password carried by the carrier card.
In an application system of the intelligent door lock, a carrier card is a user card which is matched with the intelligent door lock and carries an unlocking password of the intelligent door lock.
In practical application, the carrier card may be a radio frequency card or a contactless TM card; of course, other door cards that can be used in the smart door lock system in the prior art are also possible. The specific form of the carrier card is not limited in this application, and all of the forms belong to the protection scope of this application.
Specifically, this password of unblanking includes: random data and mixed encrypted data arranged in a preset order. The mixed encrypted data is generated by encrypting based on random data and secret data. In practical application, the unlocking password can be generated by the cloud platform, and the cloud platform and the intelligent door lock jointly hold the secret data.
After the smart door lock obtains the unlocking password, the random data can be obtained, and the secret data is pre-stored in the smart door lock, so that step S102 can be executed.
S102, based on the pre-stored data and random data in the unlocking password, a preset encryption algorithm is adopted to obtain a target unlocking password of the intelligent door lock.
The pre-stored data is secret data pre-stored in the intelligent door lock.
In practical application, step S102 is a specific process of obtaining a target unlocking password of the intelligent door lock by using a preset encryption algorithm, which can be seen in fig. 2.
S201, encrypting the random data and the secret data for multiple times to generate a plurality of target encrypted data.
Specifically, if the secret data includes the root key, the timestamp, and the lock device ID of the smart door lock itself, the specific process of encrypting the random data and the secret data for multiple times includes:
and calculating by adopting the same algorithm based on the root key, the timestamp, the locking equipment ID and the random data to obtain corresponding passwords of N preset time periods after the current timestamp, wherein the passwords are used as target encryption data. Wherein N is a positive integer.
In practical application, the value of N and the preset time interval are determined according to the NB networking interval, for example, if the NB networking interval is 24 hours, N is 3, the preset time interval is 8 hours, if the NB networking interval is 12 hours, N is 3, the preset time is 4 hours, and so on. Of course, the specific values of N and the preset time period may also be determined according to the specific application environment and the user requirements, and the application is not particularly limited and belongs to the protection scope of the application.
S202, arranging the plurality of target encrypted data and the random data according to a preset sequence to generate a plurality of passwords which are all used as target unlocking passwords.
The preset sequence can be a splicing sequence of random data before and target encrypted data after; of course, the target encrypted data can be spliced in the sequence of the front random data and the back random data. The specific manner of presetting the sequence is not limited in the present application, and all the embodiments belong to the protection scope of the present application.
Actually, the target unlocking password and the unlocking password are generated in the same manner, that is, the generation manner of each password in the target unlocking password is the same as that of the unlocking password; the following further explains the process of obtaining the unlocking code and the target unlocking code by using a specific example:
firstly, after a processing terminal in an application system of the intelligent door lock, such as a foreground computer of a hotel, responds to user operation, a password application request is sent to a cloud platform to ask for an unlocking password of the corresponding intelligent door lock. At the moment, the cloud platform responds to the password application request, and an unlocking password is calculated by adopting a preset encryption algorithm according to the random data and the confidential data jointly held by the intelligent door lock and the cloud platform.
Assuming that the number of digits of the unlocking password is six, the specific process of generating the unlocking password by the cloud platform is as follows:
a. the cloud platform first generates 2-bit random data, e.g., 28.
b. The cloud platform calculates by using a preset encryption algorithm according to the timestamp in the confidential data, the root key of the intelligent door lock, the lock device ID and the generated random data, so as to obtain mixed encrypted data 4685.
c. And arranging the random data and the mixed encrypted data according to the random data before and the mixed encrypted data after to obtain the unlocking password 284685.
And then the cloud platform returns the unlocking password to the processing terminal, and the processing terminal writes the unlocking password into the carrier card.
Then, the user carries the carrier card to perform a first door opening operation, and the intelligent door lock executes the steps S101 and S102; the method is the same as the unlocking password generation method, and if N is 3 and the preset time period is 8 hours, the specific process of obtaining the target unlocking password by the intelligent door lock is as follows:
1. the smart door lock first obtains random data in the unlock code, such as 28 above.
2. The intelligent door lock adopts a preset encryption algorithm to calculate according to the timestamp in the confidential data, the root key of the intelligent door lock, the lock equipment ID and the random data, and obtains corresponding passwords 3 after the current timestamp and 8 hours in a preset time period, wherein the passwords are respectively as follows: 4685. 5326, 9643, as target encrypted data.
3. Arranging the random data and each target data respectively according to the random data before and after the target data to obtain 3 six-digit target unlocking passwords, wherein the three target unlocking passwords are respectively as follows: 284685, 285326, 289643.
In other words, when N is 3 and the preset time period is 8 hours, the smart door lock may perform 3 times of calculation by using a preset encryption algorithm according to the root key of the smart door lock, the timestamp, the lock device ID, and the first two random data in the unlocking password, so as to obtain the password corresponding to the current timestamp and every 8 hours. That is, according to the above-described manner, the unlocking password of the smart door lock corresponding to each 8 hours within the future 24 hours of the smart door lock can be obtained as the target unlocking password. Step S103 may be performed.
And S103, judging whether the unlocking password is the same as the target unlocking password or not.
Similarly, if N is 3 and the preset time period is 8 hours, if the unlocking password carried by the carrier card is any one of the passwords within 24 hours after the current timestamp of the smart door lock, it is determined that the unlocking password is the same as the target unlocking password, and step S104 is executed.
And S104, judging that the carrier card has unlocking authority.
In practical application, as long as the unlocking password carried by the carrier card is the same as any one of the target unlocking passwords corresponding to the intelligent door lock within 24 hours before the current timestamp, in other words, if the unlocking password carried by the carrier card is the same as any one of the target unlocking passwords obtained by adopting the preset encryption algorithm in the intelligent door lock, the carrier card can be judged to have the unlocking authority.
In the implementation, the authority judgment of the carrier card can be directly realized in the process that the user uses the carrier card to open the intelligent door lock for the first time through the process; that is, the method and the device can check whether the unlocking password is correct or not by adopting the same generation mode as the unlocking password through the intelligent door lock when the NB module in the intelligent door lock is not required to be put into operation, so that whether the carrier card has the unlocking authority or not can be known.
Optionally, in another embodiment provided by the present application, please refer to fig. 3, after step S103 is executed, and it is determined whether the unlocking password is the same as any one of the target unlocking passwords, if the unlocking password is different from all the target unlocking passwords, step S301 is further included.
S301, judging that the carrier card does not have unlocking authority.
Suppose N is 3 in the same way, the preset time quantum is 8 hours, and when the unlocking password carried by the carrier card is different from the corresponding unlocking password of the intelligent door lock within 24 hours after the current timestamp, the unlocking password carried by the carrier card can be known, and the carrier card is not obtained by using the secret data and the random data jointly held by the intelligent door lock and the cloud platform, so that the carrier card can be judged not to have the unlocking authority.
Optionally, on the basis of any of the above embodiments, please refer to fig. 4 (which is shown on the basis of fig. 1 as an example), after the step S104 is executed and the carrier card is determined to have the unlocking authority, the method further includes:
s401, writing the information of the carrier card into a white list of the intelligent door lock.
It should be noted that, after the carrier card is determined to have the unlocking authority, the information of the carrier card may be written into the white list of the smart door lock by using the manner of obtaining the target unlocking password by using the same encryption algorithm as that used for generating the unlocking password, so that the carrier card becomes a user card authorized legally by the smart door lock, and when a subsequent user uses the carrier card, the subsequent user can directly pass the verification of the smart door lock.
Optionally, on the basis of any of the above embodiments, please refer to fig. 5 (which is shown on the basis of fig. 1 as an example), after the step S101 is executed to obtain the unlocking password carried by the carrier card, the method further includes:
s501, judging whether the information of the carrier card belongs to the intelligent door lock white list.
Wherein, the white list of the intelligent door lock is updated when the intelligent door lock is networked with the cloud platform.
And if the information of the carrier card does not belong to the white list, executing the step S102, and obtaining a target unlocking password of the intelligent door lock by adopting a preset encryption algorithm based on the pre-stored data and random data in the unlocking password. That is, after the result of judging the unlocking authority of the carrier card by the white list of the intelligent door lock is that the unlocking authority is not available, the subsequent steps are executed, a mode of obtaining a target unlocking password by a preset encryption algorithm is adopted, secondary judgment is carried out on whether the carrier card has the unlocking authority or not, so that when the intelligent door lock does not start the NB module and the cloud platform networking and updates the white list in the intelligent door lock, the authority judgment can still be carried out on the unlocking password carried by the carrier card through the intelligent door lock, and the mode of carrying out the authority judgment after the intelligent door lock white list is updated by starting the NB module and the cloud platform networking is not poor.
And if the unlocking password belongs to the passwords in the white list, executing the step S104 and judging that the carrier card has the unlocking authority.
In practical application, if the intelligent door lock can be before obtaining the password of unblanking that the carrier card carried, just network with the cloud platform through NB module in self, update the white list in self, then just can realize the information verification to the carrier card through this white list, and then can directly judge whether this carrier card has the authority of unblanking.
On the basis of the above-described authority determination method for an intelligent door lock, another embodiment of the present application further provides an intelligent door lock, which mainly includes:
lock body, battery, NB module, memory and treater.
Wherein, the battery is used for supplying power for intelligent lock.
The NB module is used for realizing communication between the processor and the cloud platform.
The processor is used for controlling the lock body and operating the program stored in the memory.
The program stored in the memory comprises the authority determination method of the intelligent door lock according to any embodiment.
It should be noted that, the principle and the related description of the lock body, the battery, the NB module, the memory and the processor in the intelligent door lock can refer to the prior art, and are not described in detail in this application.
It should be noted that, the principle and the related description of the authority determination method of the intelligent door lock in the program stored in the memory may refer to the embodiments corresponding to fig. 1 to fig. 5 of the present application, and are not described herein again.
Optionally, on the basis of the foregoing, an embodiment of the present application further provides an application system of an intelligent door lock, please refer to fig. 6, where the application system of the intelligent door lock mainly includes: the system comprises a processing terminal 101, a cloud platform 102, at least one carrier card 104 and at least one intelligent door lock 103 executing the authority determination method of the intelligent door lock.
The cloud platform 102 is in communication connection with the NB modules in the processing terminal 101 and the intelligent door lock 103, respectively.
The processing terminal 101 is used for responding to user operation and sending a password application request to the cloud platform 102 to ask for an unlocking password of the corresponding intelligent door lock; and receiving the unlocking password fed back by the cloud platform 102, and writing the unlocking password into the carrier card 104.
And the cloud platform 102 is used for responding to the password application request, calculating an unlocking password according to the random data and the confidential data commonly held by the intelligent door lock 103 and the cloud platform 102, and feeding the unlocking password back to the processing terminal 101.
In practical applications, the cloud platform 102 may be a server for implementing management of the processing terminal 101 and the smart door lock 103.
The processing terminal 101 may be a front end of a computer, or may be a terminal server having a processing function in any application system of the intelligent door lock. The present application is not limited to the specific form thereof, and the present application is intended to cover all such forms as fall within the scope of the present application.
In practical applications, the carrier card 104 may be a radio frequency card, and the processing terminal 101 may write the unlocking password into the radio frequency card through a radio frequency card reader.
It should be noted that if the application scenario of the application system of the intelligent door lock is a hotel, and the carrier card 104 is a radio frequency card, the processing terminal 101 is a hotel foreground and a computer for checking in. When the hotel manager transacts the check-in procedure for the guest, the computer can respond to the operation of the hotel manager and send a password application request to the cloud platform so as to ask for the unlocking password of the corresponding intelligent door lock. After receiving the unlocking password fed back by the cloud platform 102, the hotel manager can operate the processing terminal 101, and write the unlocking password into the radio frequency card through the radio frequency card reader, so that the user can open the door of the intelligent door lock by using the radio frequency card within a preset time period, for example, within 24 hours.
With reference to fig. 6 and the above description, the following further explains and explains an application system of the intelligent door lock with a specific example:
1. after the user completes the check-in procedure, the processing terminal 101 applies for a temporary password for 24 hours to the cloud platform 102 through the network.
2. The cloud platform 102 first generates a two-digit random number, then obtains other four digits through a certain algorithm by using the generated random data in combination with a timestamp, a root key of the intelligent door lock 103 and a lock device ID, and then combines the two digits and the four digits to form a six-digit password, namely an unlocking password.
3. The processing terminal 101 writes an unlocking password into a radio frequency card (namely the carrier card 101) through a radio frequency card reader, when a user opens a door for the first time by using the radio frequency card within 24 hours, if the cloud platform 102 sends information of the radio frequency card to the intelligent door lock 103 through a networking window of the intelligent door lock NB module, the intelligent door lock 103 compares the white list information of the radio frequency card, and the unlocking is performed if the verification is passed; if the radio frequency card is not in the white list of the intelligent door lock, the intelligent door lock 103 calculates the password every 8 hours behind the current timestamp by adopting the same algorithm according to the root key, the timestamp, the lock equipment ID and the first two random data of the unlocking password carried by the radio frequency card, the calculation is carried out for 3 times in total, if one 8-hour password is the same as the unlocking password of the radio frequency card, the radio frequency card is considered to be legally authorized, the information of the radio frequency card is written into the intelligent door lock 103 to form a formal card, and if not, the radio frequency card is considered to be illegal.
It should be noted that, with the random data, leakage of the secret data of the cloud platform 101 can be prevented. Moreover, the data in the radio frequency card has certain timeliness, and the data is invalidated after a certain time. The method comprises the steps that a person serves as an information carrier, random data in information is partially informed to an intelligent door lock 103, the intelligent door lock 103 obtains a target unlocking password through the same algorithm by using secret data held by a cloud platform 102 and the intelligent door lock 103, and the target unlocking password and the secret data are compared to obtain a final judgment result.
It should be noted that setting information in the carrier card 104 to be valid for a short time corresponds to writing data into the smart door lock 103 via the carrier card 104. Exceeding the time efficiency range of the information in the carrier card 104, the cloud platform 102 can be issued to the intelligent door lock 103 through the NB module channel, and then the information in the original carrier card can still pass through the verification, so that the user experience is indistinguishable. That is, this scheme utilizes the people as the passer who carries the information, makes up the non-real-time shortage of NB module communication mode, realizes the transmission of information safety ground from cloud platform 102 to intelligent lock 103 in the short time.
In other words, the scheme utilizes the operation that the user can carry the carrier card to the intelligent door lock 103 for swiping the card, namely, the user plays a role in data transmission in the communication process, the key backup of the NB module communication channel is realized, and the data safety can be ensured.
Moreover, after the intelligent door lock 103 in the application system knows that the carrier card has the unlocking authority, the unlocking password can be written into the white list of the intelligent door lock 103, so that the carrier card becomes a user card authorized by the intelligent door lock legally, and the follow-up user can be directly authenticated by the intelligent door lock 103 when using the carrier card.
In practical application, when the NB module in the smart door lock 103 is networked with the cloud platform 102, the cloud platform 102 is further configured to: and issuing the unlocking password to the intelligent door lock.
The smart door lock 103 is also used for: and receiving an unlocking password and updating a white list in the user.
It should be noted that the NB module in the smart door lock 103 is networked with the cloud platform 102, so that the information of the smart door lock 103 and the cloud platform 102 can be synchronized.
