Description

Intelligent lock control method and device

Technical Field

Background

At present, the functions of the intelligent terminal are increasingly rich. The intelligent terminal can be applied to interact with other equipment. In an application scenario of the intelligent terminal, the intelligent terminal is used for controlling the opening or closing of the intelligent lock. The intelligent lock is a lock which can be controlled and unlocked by the intelligent terminal, and comprises but is not limited to a door lock or a vehicle lock. Taking an intelligent lock as an example, an intelligent key application program (applet) for controlling the opening of a vehicle door is installed in an intelligent terminal, and a user controls the opening or closing of the vehicle lock through the applet.

When the intelligent terminal is used for unlocking the car lock, the threat of relay attack exists. When the vehicle owner is not beside the vehicle, the attacker A approaches the vehicle owner, the attacker approaches the vehicle door, the attacker A acquires a signal sent by the vehicle owner through the terminal applet through the specific device, and sends the acquired signal to the device held by the attacker B through the specific device. Therefore, the attacker B sends the signal to the lock through the equipment, and can control the lock to unlock and open the vehicle door.

Therefore, in a relay attack scene, even if the car owner is not beside the car, the attacker A and the attacker B can open the car door by acquiring the unlocking signal of the terminal held by the car owner, so that the mode of unlocking the intelligent lock has serious potential safety hazard.

The following description will take the case where the SE in the processor executes a software program and implements the unlocking control, but this is not intended to limit the present invention.

In one embodiment, taking the processor including the SE as an example, referring to fig. 4(a), the SE may be integrated in a System On Chip (SOC) 301 of the device, and in this case, the SE may be referred to as inSE. In fig. 4(a), a Power Management Unit (PMU)105 is connected to the SOC 301, and the PMU105 is further connected to the SE 1021 through a GPIO. Button 106 may be connected to SOC 301 through PMU105 and to SE 1021 through PMU 105.

The apparatus may be one or more chips, a chipset, or may selectively run software to operate.

Referring to fig. 3, a schematic diagram of a possible structure of an intelligent lock control device provided in an embodiment of the present application is shown. For example, the smart lock control device 300 may be the smart lock itself, or a component located in the smart lock, may be controlled by the terminal as previously described. In one possible implementation, the intelligent lock control device 300 may include a processor 302 and a communication device 303. Optionally, the intelligent lock control device 300 further includes a memory 301 and a bus 304. The connection relationship among the memory 301, the processor 302, the communication device 303 and the bus 304, and the functions of the respective components can be referred to the description related to fig. 2, and are not described herein again. The processor 302 may execute computer program instructions stored in the memory 301 to control the communication device 303 to implement signal transmission, or to process signals received by the communication device 303 and implement an unlocking operation of the smart lock. The operation executed by the processor 302 in the intelligent lock corresponds to the operation executed by the processor 102 in the terminal, and is used for cooperating with the processor 102 to execute an unlocking operation, so as to realize the interoperation between the intelligent lock and the terminal, thereby realizing the intelligent unlocking and ensuring the security. The specific operation flow can be shown with reference to fig. 6. It will be appreciated that the software architecture of the computer program instructions executed by the processor 302 may be similar to the software corresponding to fig. 5 or 7 executed by the processor 102 of the terminal, except that no key identification driver is included. Specifically, the software architecture may include an operating system and a key application, both of which are commonly run on the processor 302, to implement the control unlocking operation, which may be specifically referred to as operation S608 in fig. 6.

Fig. 5 is a schematic architecture diagram of software running on the processor 102 according to an embodiment of the present disclosure. The processor 102, which may be an SE in particular, may be configured to run an operating system 502, a key identification driver 503, and a key application (applet) 501. In the present embodiment, the key application 501 is also referred to as a key application, a smart key application, or the like, and the name thereof does not constitute a limitation on the key application. The key application 501 runs on the operating system 502, and can obtain information of the key operation performed by the user by calling an interface provided by the operating system 502 to access hardware and resources.

In the following description of the embodiments of the present application, the information of the user operating the key may be referred to as key information for short, so as to indicate which key is operated by the user, for example, the key information may indicate that the user performs a double-click operation on a power (power) key.

The operating system 502 provides an interface for the key application 501 to access hardware and resources. Illustratively, the operating system 502 provides an Application Programming Interface (API) for the key Application 501, and referring to fig. 5, the operating system 502 provides a security confirmation API (getsecurreconfiguration API) for the key Application 501, so that the operating system 502 may actively report the key information to the key Application 501, or the key Application 501 polls the API to obtain the key information.

And the key identification driver 503 is configured to determine information that the user operates the key, that is, determine key information, according to a control signal that the PMU reports to the processor through the GPIO. And may return the key information to operating system 502. For example, setting a double-click of the power key within 2s as an operation for triggering the control process of the intelligent lock, that is, a preset operation described below, when the key identification driver 503 detects two control signals on the GPIO within 2s, it indicates that the user performs two key pressing operations within 2s, and the key identification driver 503 reports the key information to the operating system 502.

The embodiment of the application provides an intelligent lock control method, which is used for a scene of unlocking an intelligent lock under the control of a terminal. Referring to fig. 6, the method includes the steps of:

s601, the intelligent lock sends a selection (select) command to the terminal. Accordingly, the terminal receives a select command from the smart lock. As a possible implementation, the smart lock sends a command to the terminal through the communication device 303 shown in fig. 3, for example. The select command carries an Application Identifier (AID) for indicating to open an applet corresponding to the AID in the terminal.

And S602, the terminal switches the state of the key application to an active state. Wherein the active state of the key application means that the key application is available for communicating with the smart lock for controlling unlocking of the smart lock. On the contrary, when the key application is not in an active state, the terminal cannot complete the process of controlling unlocking of the intelligent lock. Specifically, the terminal switches the applet corresponding to the AID to the active state according to the AID in the received select command. As a possible implementation, the terminal switches the state of the key application to the active state by, for example, the processor 302 shown in fig. 2.

(optional) S603, the terminal feeds back a confirmation message to the intelligent lock. Accordingly, the smart lock receives an acknowledgement message from the terminal. The confirmation message is used to confirm that the terminal has switched the key application to the active state. As a possible implementation, the active key application feeds back an acknowledgement message to the smart lock.

And S604, performing bidirectional authentication on the terminal and the intelligent lock. It can be understood that, in order to ensure the security of unlocking the intelligent lock, the terminal needs to verify whether the identity of the intelligent lock is legal, and similarly, the intelligent lock also needs to verify whether the identity of the terminal is legal. The specific manner of performing bidirectional authentication between the terminal and the intelligent lock can be referred to in the prior art, and is not described herein again. As a possible implementation, the processor 102 of the terminal performs bidirectional authentication with the smart lock through the communication device 103. Accordingly, the processor 302 of the smart lock performs bidirectional authentication with the terminal through the communication device 303.

S605, the terminal negotiates a key with the intelligent lock. In order to ensure the security of unlocking the smart lock, the unlocking information for unlocking the smart lock needs to be encrypted and/or signed and/or integrity checked, and therefore a secret key used for operations such as encryption needs to be negotiated in advance. The specific process of negotiating the key can be referred to in the prior art, and is not described herein. As a possible implementation, the processor 102 of the terminal negotiates a key with the smart lock via the communication device 103. Accordingly, the processor 302 of the smart lock negotiates a key with the terminal via the communication device 303.

Through the above S601 to S605, the terminal establishes communication connection with the intelligent lock, and it can be understood that, after the terminal establishes communication connection with the intelligent lock, the terminal can further control unlocking of the intelligent lock through information interaction with the intelligent lock. Based on this, the intelligent lock control method provided by the embodiment of the application further comprises the following steps:

and S606, receiving a response signal triggered by the operation of the key by the user, and generating a control signal based on the response signal. The key mentioned in the embodiment of the present application refers to a preset key that can trigger the terminal to execute the intelligent lock control method in the embodiment of the present application. For example, the preset key may be a power key, a volume key, other physical keys, or a combination key formed by one or more keys. The embodiment of the application does not limit the type of the preset key.

In one implementation, the operation of the user on the preset key may refer to a preset operation of the user on the preset key, where the preset operation includes, but is not limited to, a long-press operation and a short-press operation on the preset key. The short pressing operation may be a preset number of pressing operations performed on the preset key within a predetermined time, for example, double-clicking the power key 2 times within 2s, and pressing the power key 3 times within 2s may be regarded as the preset operation. The preset operation may be configured by default of the terminal or may be set by the user. Taking a preset operation set by a user as an example, referring to fig. 8 (a), the user opens an unlocking intelligent lock setting item 1002 in an interface 1001, so that the terminal has a function of controlling unlocking of an intelligent lock, and further, the terminal can execute the intelligent lock control method in the embodiment of the present application. Referring to fig. 8 (b), the user may further select a double-click power key 1004 in the interface 1003, and then, the user may trigger to unlock the smart lock by double-clicking the power key, or, select a long-press power key option in the interface 1003, and correspondingly, then, the user may trigger to unlock the smart lock by long-pressing the power key. Of course, the user may also select the new setting item 1005 in the interface 1003 and input a custom preset operation. For example, the customized preset operation is to press the power key three times within 2 s.

Taking the preset operation as a long-time pressing operation as an example, optionally, in order to prevent the user from mistakenly touching the preset key to unlock the intelligent lock, a prompt interface may be output after the user performs the preset operation on the preset key to prompt the user whether to confirm to unlock the intelligent lock. Referring to fig. 8 (c), the terminal output interface 1006: is it confirmed to unlock the smart lock? And clicking the 'yes' option by the user, and continuing to execute the intelligent lock control process by the terminal so as to control unlocking of the intelligent lock. And clicking the 'no' option by the user, and not executing the intelligent lock control process by the terminal and unlocking the intelligent lock.

Taking the example that the preset operation is long pressing of the power key, optionally, the preset operation is long pressing of the power key, and when the terminal is in a power-on state, if a user presses the power key for a long time, the terminal may be triggered to restart or shut down. At this moment, the terminal can output an interface for prompting the user whether to confirm that the preset operation is used for unlocking the intelligent lock. Referring to fig. 8 (d), the terminal output interface 1007, the user may trigger the smart lock unlocking process by selecting the "unlock" option.

As a possible implementation manner, in a preset time period after the connection with the intelligent lock is established, the terminal monitors the operation of the user on the key. The principle of the terminal monitoring the operation of the user on the key is as follows: the operation of the key by the user triggers a response signal, the response signal is transmitted to the PMU, and the PMU generates a control signal based on the response signal and provides the control signal to the processor through the GPIO. In this way, the processor of the terminal may wait for the reading of the control signal on the GPIO within a preset time, and may determine the operation of the key by the user, for example, within 2s, the processor may wait for the signal caused by the above operation, for example, within 2s, by waiting for the two control signals read on the GPIO, it may be stated that the user has performed two pressing operations on the key within 2 s. As follows, taking the NFC protocol communication between the smart lock and the terminal, taking a preset time period of 10S as an example, the user holds the terminal to approach the smart lock, and establishes a communication connection with the smart lock through S601 to S605, and within 10S from the establishment of the communication connection, the terminal monitors the operation of the user on the preset key (for example, the user double-clicks the power key within 2S), which indicates that the intention of the user is to unlock the smart lock, and the terminal may continue to perform step S607. If the user does not monitor that the user double-clicks the power key within 10S from the beginning of the communication connection between the terminal and the intelligent lock after the terminal is held by the hand and the intelligent lock is close to the intelligent lock, the intention of the user is not to unlock the intelligent lock, and the terminal does not execute the step S607 for controlling unlocking the intelligent lock, so that the probability of mistakenly triggering the process of unlocking the intelligent lock is reduced, and the safety problem caused by mistakenly triggering the unlocking of the intelligent lock is reduced.

S607, responding to the control signal, and the terminal sends unlocking information to the intelligent lock. Correspondingly, the intelligent lock receives unlocking information from the terminal. The unlocking information comprises indicating information used for indicating the operation of the key by a user, and the unlocking information is used for unlocking the intelligent lock.

As described in S606, the terminal monitors the control signal on the GPIO to determine whether the user performs a preset operation on the preset key (for example, presses the power key 2 times within 2S), and when it is determined that the user performs the preset operation on the preset key, the terminal sends unlocking information to the smart lock. As a possible implementation, the key application 501 of the terminal sends the unlocking information to the smart lock by calling the communication device 103.

For example, the indication information indicating the preset operation may be represented by 1bit, and when the indication information is 1, it indicates that the terminal monitors the preset operation of the user on the preset key, and when the indication information is 0, it indicates that the terminal does not monitor the preset operation of the user on the preset key within the preset time period. Of course, the indication information indicating the preset operation may also be represented in other forms, and the embodiment of the present application does not limit the specific form of the indication information.

As a possible implementation manner, in order to improve the security of the unlocking information, the unlocking information transmitted in the communication may be processed. For example, the unlocking information is processed by using the key negotiated in the above-described flow. The key involved in the embodiment of the present application includes, but is not limited to, a private key of the terminal, a public key of the terminal, a private key of the smart lock, a public key of the smart lock, and a Message Authentication Code (MAC) key.

Optionally, the terminal signs the unlocking information and sends the signed unlocking information to the smart lock. Specifically, the terminal processes the unlocking information by using a preset algorithm to generate an abstract of the unlocking information, and then signs the abstract. For example, the terminal calculates the digest of the unlocking information using a hash function, and signs the digest using its own private key. Optionally, the terminal encrypts the unlocking information and sends the encrypted unlocking information to the smart lock. Specifically, the terminal encrypts the unlocking information and the digest of the signature by using the public key of the intelligent lock to obtain a ciphertext.

Correspondingly, after the intelligent lock receives the encrypted unlocking information, the cipher text is decrypted by using the private key of the intelligent lock, and the plaintext of the unlocking information and the digest of the signature are obtained. And then, the intelligent lock uses the public key of the terminal to sign off the digest of the signature. Therefore, only the public key of the terminal can sign the signature of the terminal, and the intelligent lock can confirm that the unlocking information is sent by the terminal. Only the private key of the intelligent lock can decrypt the ciphertext encrypted by the public key of the intelligent lock, so that the terminal can confirm that the unlocking information can only be read by the intelligent lock.

Optionally, the terminal and the intelligent lock perform integrity protection on the unlocking information. Specifically, the terminal calculates the MAC of the unlocking information and sends the MAC and the unlocking information to the smart lock. After receiving the MAC and the unlocking information, the intelligent lock carries out integrity check on the MAC and the unlocking information so as to ensure the integrity of the unlocking information. For specific ways of encryption and decryption, signature, de-signature, and integrity protection, reference may be made to the prior art, and details are not described here.

And S608, responding to the unlocking information to control unlocking of the intelligent lock. The intelligent lock receives the unlocking information, and the user performs preset operation on the preset key, namely the user intends to unlock the intelligent lock, and at the moment, the intelligent lock is unlocked. Illustratively, the unlocking information received by the intelligent lock includes indication information 1, which indicates that the user performs a preset operation on a preset key, and the intelligent lock is unlocked to respond to the unlocking requirement of the user.

According to the intelligent lock control method, the preset operation of the user on the preset key is monitored, and the unlocking information is sent to the intelligent lock based on the operation of the user on the key so as to control unlocking of the intelligent lock. The operation of the user on the key indicates that the user intends to unlock the intelligent lock, so that the probability of mistakenly triggering the intelligent lock unlocking process can be reduced. And under the trigger of the key operation of the vehicle owner, the intelligent lock can be unlocked, and the safety of unlocking the intelligent lock can be improved.

Further, by adopting the intelligent lock control method provided by the embodiment of the application, even if the terminal is in a power-off state, when the terminal approaches the intelligent lock, the PMU can be powered on due to strong field intensity of the intelligent lock, the terminal is powered on, the intelligent lock unlocking process is executed, and the success probability of unlocking the intelligent lock is improved. At this time, the PMU may only turn on the terminal without lighting the screen of the terminal, so as to reduce power consumption of the terminal.

The intelligent lock control method provided by the embodiment of the application is introduced. It is understood that the terminal or the smart lock includes a hardware structure and/or a software module for performing the respective functions in order to realize the above functions. Those of skill in the art will readily appreciate that the present application is capable of implementing the exemplary structures and algorithm steps described in connection with the embodiments disclosed herein in a combination of hardware and computer software. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present application.

The intelligent lock control device related to the above embodiment may be a system-level device. The software part or the hardware part inside the intelligent lock control device can be independently and specifically used for realizing the intelligent lock control function. Fig. 7 shows a schematic diagram of a possible structure of an intelligent lock control device according to the present embodiment. The intelligent lock control device corresponds to the software portion of fig. 5, and may be run on the processor 102, which may be specifically an SE. See fig. 7. The device comprises a key identification driver 503 and a control unit 701 as shown in fig. 5. The key identification driver 503 is configured to receive a control signal from the receiving device. Where the receiving device is, for example and without limitation, PMU105 shown in fig. 2, the control signal is generated by PMU105 based on a response signal triggered by user operation of a key. The key identification driver 503 is also used to provide control signals to the control unit 701.

In this way, the key application can acquire whether the user operates the key through the API. When the key application learns that the user operates the key (for example, presses the power key 2 times within 2 s), the key application calls the communication device to send unlocking information to the smart lock under the control of the control unit 701. For example, the key application calls the NFC module to send unlocking information to the smart lock.

In a possible embodiment, the key identification driver 503 is specifically configured to listen to the control signal from the receiving device for a preset time period after establishing a communication connection with the smart lock. For example, the preset time period is 10s, and in 10s from the beginning of establishing connection between the terminal and the intelligent lock, if the key identification driver monitors a control signal transmitted to the processor by the PMU through the GPIO (for example, two control signals exist on the GPIO within 2 s), the terminal sends unlocking information to the intelligent lock to indicate to unlock the intelligent lock. On the contrary, within 10s from the connection establishment between the terminal and the intelligent lock, if the key identification driver does not monitor the control signal pair preset from the receiving device, the terminal may not send the unlocking information to the intelligent lock.

Optionally, the control unit 701 is further configured to control the communication device to execute S604 in the flow shown in fig. 6, that is, perform bidirectional authentication with the intelligent lock through the communication device to determine the validity of the identity of the intelligent lock. Optionally, the transmitted unlocking information is encrypted by a key. Correspondingly, the control unit 701 is further configured to control the communication device, so that the communication device executes S605 in the flow shown in fig. 6, that is, the communication device negotiates the key with the smart lock.

In one possible implementation manner, with reference to fig. 1 to 5, when the control unit 701 and the key identification driver 503 are implemented in software, respectively, software programs corresponding to the functional modules are included in the memory 101, and the processor 102 executes the software programs including the functional modules included in the memory 101 to implement functions corresponding to the functional modules.

Optionally, the key application sends unlocking information to the smart lock, which may be specifically implemented as: the key application calls the communication device of the terminal through an API provided by the operating system, so that the communication device performs S607 in the flow shown in fig. 6, that is, sends the unlocking information to the smart lock. For example, the key application calls an NFC module of the terminal through an API provided by the operating system, and the terminal sends the unlocking information to the smart lock through the NFC module.

In a possible implementation manner, the key application is configured to obtain, from an operating system, an operation of a key by a user, and send unlocking information to the smart lock, and specifically includes: and the method is used for acquiring the operation of the user on the key in a preset time period after the connection between the terminal and the intelligent lock is established. Illustratively, the preset time period is 10s, and within 10s after the terminal is connected with the intelligent lock, the key application acquires the pre-operation of the key by the user from the operating system, and then the key application sends unlocking information to the intelligent lock to indicate to unlock the intelligent lock. On the contrary, within 10s from the establishment of the connection between the terminal and the smart lock, if the key application does not acquire the preset operation of the user on the preset key from the operating system (for example, to acquire the double-click operation on the power key), the key application may not send the unlocking information to the smart lock.
