In one possible implementation, the user communication module 13 is connected to the terminal device 18 using bluetooth low energy. In some embodiments, bluetooth low energy may send a connectible broadcast message once every specified duration (e.g., one second) to enable terminal device 18 to access bluetooth low energy via the connectible broadcast message. After the user communication module 13 establishes a communication connection with the terminal device 18, communication can be performed. At the same time, the user communication module 13 establishes communication connection with only one terminal device 18. If the user communication module 13 has already completed the establishment of the communication connection with a certain terminal device, the connection request of other terminal devices is not received any more. If the user communication module 13 is currently establishing communication connection with a certain terminal device, the connection request of other terminal devices is not received any more until the connection request of any terminal device is continuously received after the communication connection is established.
In some embodiments, the user communication module 13 may obtain user authentication information from the terminal device 18 after establishing a communication connection with the terminal device 18. In addition, the user communication module 13 can establish a first channel with the background server 19 by means of the terminal device 18, the first channel can perform data transmission between the user communication module 13 and the background server 19, and the terminal device 18 does not perform any operation on data transmitted in the communication process, so that the privacy and the safety of communication are ensured. The user communication module 13 may send a user connection request to the security module 14 after establishing a communication connection with the terminal device 18, such that the security module 14 sends a locally stored public key to the user communication module 13 after receiving the user connection request (S201), and sends the public key to the background server 19 through the first channel via the user communication module 13 (S102).
In some embodiments, the user authentication information may be information capable of representing an identity of a user of the terminal device. The user authentication information may include a user name and a password. The terminal device 18 performs user input detection in the case of being connected to the user communication module 13, obtains a user name and a password input by the user, and transmits the user name and the password to the user communication module 13 through the connection established between the terminal device 18 and the user communication module 13 (S402). The user name can be a mobile phone number of the user, or can be other numbers and/or letters set by the user according to habits, and the user names of different users are different. In some embodiments, each user name may correspond to real name information of the corresponding user, which may improve unlocking security of the smart padlock device.
In this embodiment, after the user communication module 13 obtains the user authentication information, the user authentication information is sent to the security module 14 (S104), so that the security module 14 encrypts the user authentication information by using the private key and returns the encrypted user authentication information (S202, S203), and after the user communication module 13 sends the encrypted user authentication information to the backend server 19 through the first channel (S105), the backend server 19 may decrypt the encrypted user authentication information by using the received public key to obtain the user authentication information, and then authenticate the user authentication information according to the recorded information of the user allowed to perform the unlocking operation on the device, determine whether the user authentication information can pass through authentication, obtain the user authentication result, encrypt the user authentication result by using the public key, and send the encrypted user authentication result to the user communication module 13 through the first channel (S301, S302).
The user authentication result may be authentication pass or authentication fail. The authentication pass may refer to that the user described in the user authentication information may unlock, which is a user recorded by the background server 19 and allowed to perform an unlocking operation on the device. The authentication passes include that each piece of information in the user authentication information matches each piece of information of the openable user stored in the background server 19, respectively. For example, the condition for authentication to pass may include: the encrypted user authentication information can be decrypted by using the public key to obtain user authentication information, the user name in the user authentication information is the user name of the unlocking user stored by the background server 19, and the password in the user authentication information is the same as the password of the unlocking user; otherwise, the authentication is not passed. The person skilled in the art can set the condition for passing authentication according to the information contained in the user authentication information, which is not particularly limited in the present disclosure.
In some embodiments, after receiving the user authentication result, the user communication module 13 transmits the user authentication result to the security module 14 (S106) to receive authentication passing information or a disconnection instruction returned by the security module 14 based on the user authentication result.
If the user communication module 13 receives the authentication passing information, it may be determined that the currently connected terminal device 18 may perform an unlocking operation on the apparatus, and continue to maintain the connection with the terminal device 18, so as to receive the request sent by the terminal device 18 to the user communication module 13. Also, after receiving the authentication passing information, the user communication module 13 may transmit an authentication passing report to the terminal device 18. The terminal device 18 may display an unlock icon in the display page in the case of receiving the authentication pass report. The terminal device 18 may generate an unlock request in the case where it is detected that the unlock icon is triggered, or other trigger operation for requesting unlocking, and transmit the unlock request to the user communication module 13 (S403).
In some embodiments, after the user communication module 13 sends the received unlocking request to the security module 14 (S108), the security module 14 may encrypt the unlocking request with the private key and return to the user communication module 13 (S210, S211). The user communication module 13 transmits the encrypted unlocking request to the background server 19 through the first channel (S109). The background server 19 may decrypt the encrypted unlocking request with the received public key to obtain the unlocking request, then determine the unlocking request according to the recorded limiting information allowing the unlocking operation to be performed on the device, determine whether the unlocking request can be allowed, obtain the request result, encrypt the request result with the public key, and send the encrypted request result to the user communication module 13 through the first channel (S303, S304).
Wherein the definition information may indicate an unlocking time interval during which an unlocking operation can be performed on the device. The request result may include both request pass and request fail. The condition of passing request can be that the moment of receiving unlocking request is in unlocking time interval, otherwise, it is not passing. The present disclosure is not particularly limited as to the condition under which the backend server 19 determines that the unlock request passes.
If the request result is that the request passes, the request result further includes a first unlocking password randomly generated by the background server 19. The background server 19 may send the second unlock code to the terminal 18 by sending a short message. The first unlocking password and the second unlocking password are the same password, the password can be composed of a plurality of numbers, symbols and the like, and the password is generated when the background server determines that the request result is that the request passes. For example, there may be a combination of 6 random numbers. When receiving the second unlock code transmitted from the background server 19, the terminal device 18 detects the user input to obtain the second unlock code input by the user (S404), and transmits the second unlock code input by the user to the user communication module 13 (S405), and the user communication module 13 transmits the second unlock code from the terminal device 18 to the security module 14 (S112). In this way, the background server 19 dynamically generates the password (i.e., the first unlocking password and the second unlocking password), so that the unlocking safety can be ensured, and the problem that the unlocking password is cracked is not worry.
In some embodiments, the user communication module 13 forwards the second unlocking password to the security module 14 after receiving the second unlocking password (S112), and the user communication module 13 is further configured to forward the received request result to the security module 14 (S110), and then the user communication module 13 receives an unlocking instruction or a disconnection instruction returned by the security module 14. When the user communication module 13 receives the unlock command, the unlock command is transmitted to the control module 15 (S113).
In the present embodiment, if the user communication module 13 receives a disconnection instruction, it is determined that the currently connected terminal device 18 cannot perform an unlocking operation for the apparatus, and the connection with the terminal device 18 is disconnected. Therefore, the safety of the device can be protected, illegal unlocking of illegal users can be avoided, and unlocking of illegal users in an illegal unlocking time interval can also be avoided.
In this embodiment, the security module 14 may store a public key and a private key, where the public key and the private key may be determined based on an RSA algorithm or the like. After the public key is sent to the background server 19 through the first channel, the background server 19 can encrypt information such as a user authentication result required to be sent to the user communication module 13 through the public key and decrypt information received from the user communication module 13 through the public key in a process of communicating with the user communication module 13. The security module 14 itself may encrypt information such as user authentication information that the device needs to send to the background server 19 via the user communication module 13 using a private key and decrypt information received from the background server 19 via the user communication module 13 using the private key. In this way, the unlocking safety of the device can be ensured by encrypting and decrypting the information transmitted by the communication between the user communication module and the background server by using the private key and the public key. And the terminal equipment only provides a first channel for communication between the user communication module and the background server, and the terminal equipment does not participate in the information interaction process, so that the reliability and the safety of the communication process can be ensured.
In the present embodiment, the security module 14, upon receiving the user authentication result transmitted from the user communication module 13 (S204), determines whether the private key can decrypt the user authentication result (S205), generates a disconnection instruction if the private key cannot decrypt the user authentication result (S208), and transmits the disconnection instruction to the user communication module 13. If the private key can decrypt the user authentication result, it is continued to determine whether the decrypted user authentication result is authentication pass (S206). If the user authentication result is that the authentication is not passed, a disconnection instruction is generated (S208), and the disconnection instruction is transmitted to the user communication module 13. If the user authentication result is authentication pass, authentication pass information is generated (S207), and the authentication pass information is transmitted to the user communication module 13 (S209). In this way, the security module 14 can determine whether the user authentication result can be decrypted or not and the content of the user authentication result, so that the security of the user authentication result can be ensured, and the unlocking security and reliability can be further improved through double determination.
In the present embodiment, the security module 14, upon receiving the request result transmitted by the user communication module 13 (S212), determines whether the private key can decrypt the request result (S213). If the private key cannot decrypt the request result, a disconnection instruction is generated (S217), and the disconnection instruction is transmitted to the user communication module 13. If the private key can decrypt the request result, it is continued to determine whether the decrypted request result is passed (S214). If the request is not passed as a result of the request, a disconnection instruction is generated (S217), and the disconnection instruction is transmitted to the user communication module 13. If the request result is that the request passes, the first unlocking code in the request result is obtained, and then it is determined whether the second unlocking code is identical to the first unlocking code according to the second unlocking code received from the terminal device 18 and forwarded by the user communication module 13 (S215). If the second unlocking password is different from the first unlocking password, a disconnection instruction is generated (S217), and the disconnection instruction is transmitted to the user communication module 13. If the second unlocking code is the same as the first unlocking code, an unlocking instruction is generated (S216), and the unlocking instruction is transmitted to the user communication module 13 (S218). In this way, the security module 14 can determine whether the request result can be decrypted or not and the content of the request result, so that the security of the request result can be ensured, and the security and reliability of unlocking can be further improved through double determination.
In a possible implementation, the security module 14 is further configured to generate a disconnection instruction and send the disconnection instruction to the user communication module 13 in case it is determined that a disconnection condition is met.
Wherein the connection disconnection condition includes at least one of:
the private key cannot decrypt the user authentication result;
the user authentication result is that the authentication is not passed;
the private key cannot decrypt the request result;
the request result is that the request does not pass;
the second unlocking password is different from the first unlocking password.
In a possible implementation, the security module 14 is further configured to regenerate a new public key and a new private key after generating the unlocking instruction, and replace the stored public key and private key with the new public key and the new private key.
In some embodiments, the public and private keys stored by the security module 14 may be dynamically randomly generated, and the security module 14 replaces the stored public and private keys with newly generated public and private keys for use in the next unlock such that the public and private keys are different for each unlock. Therefore, the safety and the reliability of the communication content can be further ensured by using the dynamically updated public key and the dynamically updated private key, and the safety and the reliability of unlocking are realized.
Fig. 3 illustrates a schematic diagram of a smart padlock device according to an embodiment of the present disclosure. As shown in fig. 3, in a possible implementation manner, the apparatus may further include: a monitoring module 21 and a management communication module 22.
The monitoring module 21 is configured to monitor an open/close state of the electronic lock 17 in real time, and send the open/close state to the management communication module 22 through the control module 15.
The management communication module 22 is configured to generate status change information and send the status change information to the background server 19 when the open/close status of the electronic lock 17 is changed.
In some embodiments, the monitoring module 21 monitors the open/close state of the electronic lock 17 in real time, and may send the monitored open/close state to the control module 15 at intervals of a certain period (e.g. one second), and the control module 15 forwards the open/close state to the management communication module 22 after receiving the open/close state. When the management communication module 22 detects that the currently received open/close state of the electronic lock 17 is different from the recorded last received open/close state of the electronic lock 17, it may generate state change information and send the state change information to the background server 19.
The state change information may indicate that the device changes from a locked state to an unlocked state, or that the device changes from an unlocked state to a locked state; the state change information may also indicate a change time at which the open/close state change occurs. When receiving the status change message, the background server 19 can determine whether or not there is an abnormality in the status change based on the status change information and the recorded opening/closing record for the device. If the background server 19 determines that there is an abnormality in the state change, it may send an abnormality alert message to a terminal device such as a mobile phone or a computer having management authority, which is connected to the smart padlock device. If the background server 19 determines that there is no abnormality in the state change, the open/close record is updated.
Wherein the open-close record may be used to record the following information: change time of state change of the device; user authentication information corresponding to the change time, and a user authentication result and/or an unlocking request and a request result thereof; determining the user authentication result and/or the time information of the request result; etc. The background server 19 determining that there is an abnormality in the state change may be: the instructed state change and change time in the state change message do not match any of the open/close records.
The user of the terminal equipment such as the mobile phone and the computer with the management authority can be a worker who manages the background server, a worker who manages the intelligent padlock device, and the like. The staff can respond to the abnormal warning message in time to process in time. Therefore, a worker can timely know whether the opening and closing of the device are abnormal or not, and the abnormal opening and closing state of the device caused by man-made or device faults can be dealt with, for example, if a user uses a violence means to destructively open the electronic lockset, the abnormal warning message can timely inform the worker.
In a possible implementation manner, the management communication module 22 is further configured to send, when receiving the status query request sent by the background server 19, the current open/close status of the electronic lock 17 monitored by the monitoring module 21 in real time to the background server 19. So that the current opening and closing state of the electronic lockset can be queried by directly connecting to the background server.
In one possible implementation, the management communication module 22 communicates with the background server through a narrowband internet of things.
In some embodiments, a narrowband internet of things (Narrow Band Internet of Things, NB-IoT) is built to a cellular network. NB-IoT can be deployed directly on global system for mobile communications network (Global System for Mobile Communications, GSM), universal mobile telecommunications system network (Universal Mobile Telecommunications System, UMTS) or long term evolution network (Long Term Evolution, LTE) to reduce deployment costs. The advantages of NB-IoT are low power consumption, wide range, large connectivity.
In a possible implementation, the monitoring module 21 is further configured to send the open and closed states to the user communication module 13. The user communication module 13 is further configured to send unlocking success information to the terminal device 18 when it is determined that the electronic lock 17 is unlocked according to the open/close state.
In this implementation, the monitoring module 21 is further configured to send the open-closed state to the user communication module 13 after sending the open-closed state to the control module 15, and the control module 15 is further configured to send the open-closed state to the user communication module 13. The user communication module 13 may send unlocking success information to the currently connected terminal device 18 in case it is determined that the open-close state is received and that the electronic lock has been unlocked. The terminal device 18 may send a success alert to the user when receiving the unlocking success information, for example, pop up a prompt box indicating that the unlocking is successful on a display page of the terminal device 18.
Fig. 4 illustrates a schematic structure of a power management module according to an embodiment of the present disclosure. As shown in fig. 4, in one possible implementation, the power management module 12 may include: super capacitor 23, power management unit 24.
The power management unit 24 is configured to receive the first electrical energy.
The power management unit 24 is further configured to perform at least one of the following operations:
and under the condition that the first electric energy is determined to be larger than the total electric energy required by the device, supplying power for the device by utilizing part of the first electric energy corresponding to the total electric energy after voltage stabilization treatment. And inputting the remaining electric energy in the first electric energy into the super capacitor 23, wherein the super capacitor 23 is further used for storing the received remaining electric energy as second electric energy.
And under the condition that the first electric energy is determined to be equal to the total electric energy required by the device, supplying power to the device by using the first electric energy after the voltage stabilization treatment.
In case it is determined that the first power is smaller than the total power, the device is powered with the second power stored in the super capacitor 23. And inputting the first electric energy into the super capacitor 23, wherein the super capacitor 23 is further used for storing the received first electric energy as second electric energy.
In case it is determined that the first power is not received, the device is powered with the second power stored in the super capacitor 23.
In some embodiments, the power management unit 24 may be PMU (Power Management Unit). PMU is a highly integrated power management scheme for portable applications, i.e., integrating conventional discrete power management devices of several types within a single package, which allows for higher power conversion efficiency and lower power consumption, as well as fewer component counts to accommodate reduced board level space.
In some embodiments, the power management unit 24 may select whether to power the smart padlock device with the first power or the second power based on a magnitude relationship of the first power to a total power required by the smart padlock device. The super capacitor 23 may store part (i.e. the remaining electric energy) or all of the first electric energy input by the power management unit 24, so that the power management unit 24 uses the second electric energy stored in the super capacitor 23 to supply power to the intelligent padlock device in the case of insufficient ambient light such as cloudy days or nights.
In some embodiments, since the light energy collecting plates are used for independently absorbing light energy, the first electric energy converted by the collected light energy has a difference in current magnitude, and the like, and therefore, diodes can be arranged between the light energy collecting plates for reverse isolation.
It should be noted that although the above embodiments have been described as examples of smart padlock devices, those skilled in the art will appreciate that the present disclosure should not be limited thereto.
