Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
An intelligent lock device according to an embodiment of the invention is described below with reference to fig. 1 and 2.
Fig. 1 is a block diagram of an intelligent lock device according to an embodiment of the present invention, and as shown in fig. 1, an intelligent lock device 1 according to an embodiment of the present invention includes an internet of things module 10, a master driver board 20, and an intelligent lock body 30.
Wherein, thing networking module 10 is used for receiving the information of unblanking, and wherein the information of unblanking includes the identity information of instruction of unblanking and the instruction sender of unblanking, for example, can send the instruction of unblanking through intelligent terminal such as cell-phone APP, and the server sends the instruction of unblanking after receiving this instruction and gives the thing networking module 10 of corresponding vehicle, and thing networking module 10 can be the equipment that has the data communication function such as wifi module, lora communication module etc.. The internet of things module 10 receives the unlocking information, verifies the identity information of the unlocking instruction sender, and when the identity information is valid, for example, when the identity information is matched with the pre-stored identity information of a legal unlocking person, the unlocking instruction sender is considered to be not authorized to unlock, and when the identity information of the unlocking instruction sender is verified to be valid, the unlocking instruction is sent to the main control drive board 20.
The main control drive board 20 is connected to the internet of things module 10, and is configured to generate a first key according to characteristic information of the smart lock body, encrypt the first key and the unlocking instruction according to an encryption algorithm, generate an unlocking control signal carrying the first key and the unlocking instruction, and send the unlocking control signal to the smart lock body 30. The characteristic information of the smart lock body 30 may include information that can identify the identity of the smart lock body 30, and includes inherent information and preset information, and in some embodiments, the characteristic information may include chip identity information and a set user identification code, and the user identification code may be a distinguishing number, a symbol, and the like defined for a user to distinguish a legitimate user. The basic process of data encryption is to process the original plaintext file or data according to some algorithm to make it become an unreadable segment of code, usually called "ciphertext", so that it can only display the original content after inputting the corresponding key, and the purpose of protecting the data from being stolen and read by the illegal person is achieved through such a way. For example, the encryption algorithm may employ one or more of a symmetric encryption algorithm, an asymmetric encryption algorithm, a Hash algorithm, and the like. In the embodiment of the invention, the unlocking instruction is encrypted by the main control drive board 20 by using an encryption algorithm and is transmitted to the intelligent lock body 30 in a ciphertext mode, so that the data security can be improved, and the probability of being stolen can be reduced.
The intelligent lock body 30 is connected with the main control drive board 20 and is configured to generate a second key according to the characteristic information of the intelligent lock body, decrypt the unlocking control signal to obtain an unlocking instruction and the first key, and execute an unlocking action according to the unlocking instruction when the first key is determined to be correct according to the second key, where a decryption algorithm of the intelligent lock body 30 is matched with an algorithm for encrypting the first key in the main control drive board 20. Specifically, when receiving the request of the master control driver board 20, the smart lock body 30 sends its own feature information to the master control driver board 20, and generates a key according to its own feature information, where the key is matched with the key generated by the master control driver board 20 according to the feature information, for example, the two are consistent or complementary or satisfy other matching principles. After receiving the ciphertext of the unlocking control signal, the smart lock body 30 decrypts the ciphertext to obtain the first key and the unlocking instruction, if the second key is matched with the first key, the correct first key is obtained, the unlocking action is executed according to the unlocking instruction, and when the first key is incorrect, the unlocking is refused, so that the vehicle battery is prevented from being stolen due to malicious unlocking, and the safety is improved.
Further, in the embodiment of the present invention, data between the intelligent lock body 30 and the main control driving board 20 is encrypted and then transmitted in a ciphertext manner, so as to improve security. Specifically, after receiving the unlocking instruction, the main control drive board 20 sends a request to the intelligent lock body 30, the intelligent lock body 30 transmits the chip identity information and the user identification code to the main control drive board 20, and the main control drive board 20 generates a first key according to an encryption rule by using the chip identity information and the user identification code, where the key is a parameter that is input in an algorithm for converting a plaintext into a ciphertext or converting the ciphertext into the plaintext, and the encryption rule may be set as a relationship rule between an addition, subtraction, multiplication and division algorithm or other set symbols. Further, the main control drive board 20 encrypts the unlocking instruction and the first key according to an encryption algorithm to generate an unlocking control signal carrying the unlocking instruction and the first key, and sends the unlocking control signal to the smart lock body 30 as message data, the smart lock body 30 decrypts the message data plaintext after receiving the message data plaintext to obtain the unlocking instruction and the first key, and compares the first key with a second key generated according to the chip identity information of the first key and the user identification code, when the first key is consistent with the second key, it is determined whether the first key is correct, that is, the unlocking user is legal, otherwise, it is determined that the first key is incorrect, and the unlocking action is executed according to the unlocking instruction only when the first key is correct. Because the characteristic information of each intelligent lock body 30 is different, the first secret keys are different, and the data communication adopts ciphertext transmission, so that the safety of the intelligent lock body can be ensured.
In some embodiments, the plaintext message data transmitted by the main control driving board 20 to the intelligent lock body 30 includes random numbers, that is, variable and uncertain values each time, so as to ensure that ciphertexts transmitted each time are different, increase the difficulty of cracking the message, and further improve the security.
In some embodiments, the encryption rule used by the master control driving board 20 to generate the first key is different from the encryption rule used by the smart lock body 30 to generate the second key, which may further improve the information security.
In some embodiments, the encryption algorithm between the main control drive board 20 and the intelligent lock body 30 adopts a TEA encryption algorithm, and cipher text transmission is adopted, and the intelligent lock body 30 and the main control drive board may adopt different encryption rules, that is, different encryption rules may be used for uplink and downlink of data, so as to improve data security. The TEA encryption algorithm is a block cipher algorithm, and the plaintext cipher text block is 64 bits, and the key length is 128 bits. The TEA algorithm uses an ever increasing Delta value as a change so that the encryption is different for each round, the number of iterations of the encryption algorithm can vary, and its reliability is guaranteed by the number of encryption rounds rather than the complexity of the algorithm. Therefore, the TEA encryption algorithm is simple in algorithm, strong in differential analysis resistance, high in encryption speed and high in safety, and accordingly the safety of data transmission can be improved.
In an embodiment, as shown in fig. 2, the intelligent lock body 30 communicates with the main control driver board 20 through an I2C interface, and the main control driver board 20 communicates with the internet of things module 10 through a UART interface. The intelligent lock body 30 can comprise a lock control panel 31, a direct current speed reducing motor 32, a motor position switch 33 and a bolt state switch 34, and after the mobile phone APP terminal sends an unlocking instruction, the server receives the unlocking instruction and sends the unlocking instruction to the Internet of things module 10 of the corresponding vehicle; the internet of things module 10 receives the unlocking instruction and then issues the unlocking instruction to the main control drive board 20; the main control driving board 20 sends an unlocking instruction to the intelligent lock body 30 after receiving the unlocking instruction; finally, after receiving the lock state information, the intelligent lock body 30 controls the dc geared motor 40 to operate, performs an unlocking action, and feeds back the lock state information to the main control driving board 20, for example, feeds back the motor position detected by the motor position switch 33 and the lock tongue state detected by the lock tongue state switch 34.
Further, the internet of things module 10 may be further configured to receive firmware upgrade information of the smart lock body 30, so as to update the user identification code and the encryption rule of the smart lock body 30. Specifically, the internet of things module 10 may periodically send a firmware upgrade request, after receiving the firmware upgrade request, the server issues firmware upgrade information corresponding to the intelligent lock device to the internet of things module 10 corresponding to the vehicle, the internet of things module 10 sends the firmware upgrade information to the main control drive board 20, the main control drive board 20 encrypts the firmware upgrade information and then issues the encrypted firmware upgrade information to the intelligent lock body 30, the intelligent lock body 30 may decrypt the encrypted firmware upgrade information to obtain new firmware upgrade information, and then may update the user identification code and the encryption rule thereof, and upgrade other functions, etc., thereby implementing remote upgrade of the firmware function thereof, may aperiodically change the encryption key and the user identification code thereof, and improve security.
Based on the above embodiment of the intelligent lock device, a scooter according to a second aspect of the present invention is described below.
Fig. 3 is a block diagram of a scooter according to an embodiment of the present invention, and as shown in fig. 3, the scooter 100 includes a scooter body 2, a power battery 3 and the intelligent lock device 1 of the above embodiment, wherein the structure and operation of the intelligent lock device 1 can refer to the description of the above embodiment.

The following describes a smart lock body control method proposed according to an embodiment of the third aspect of the present invention with reference to the accompanying drawings.
Fig. 4 is a flowchart of an intelligent lock body control method according to an embodiment of the present invention, and as shown in fig. 4, the intelligent lock body control method according to the embodiment of the present invention at least includes steps S1-S3, each of which is detailed as follows.
And S1, receiving unlocking information, wherein the unlocking information comprises an unlocking instruction and identity information of an unlocking instruction sender.
For example, an internet of things module can be arranged, after the intelligent terminal sends an unlocking instruction, the server issues the unlocking instruction to the internet of things module of the corresponding vehicle, and remote unlocking instruction sending is achieved.
And S2, verifying whether the identity information of the unlocking instruction sender is valid.
For example, when the identity information of the unlocking instruction sender is matched with the pre-stored identity information of a legal unlocking person, the unlocking instruction sender is considered to be valid, otherwise, the unlocking instruction sender is considered to have no authority to unlock, the unlocking instruction is refused to be issued, and the unlocking information is returned to be received; and when the identity information of the unlocking instruction sender is verified to be valid, the unlocking instruction is sent to the main control drive board, and the step S3 is executed.
And S3, generating a first key according to the characteristic information of the intelligent lock body, and encrypting the unlocking instruction and the first key according to an encryption algorithm to generate an unlocking control signal carrying the first key and the unlocking instruction.
The basic process of data encryption is to process the original plaintext file or data according to some algorithm to make it an unreadable segment of code, usually called "ciphertext", so that it can only display the original content after inputting the corresponding key, and the purpose of protecting the data from being stolen and read by an illegal person is achieved through such a way. For example, the encryption algorithm may include a symmetric encryption algorithm, an asymmetric encryption algorithm, and a Hash algorithm. In the embodiment of the invention, the unlocking instruction is encrypted through the encryption algorithm and transmitted in a ciphertext mode, so that the data security can be improved, and the probability of being stolen can be reduced.
And S4, generating a second key according to the characteristic information, decrypting the unlocking control signal to obtain an unlocking instruction and the first key, and controlling the intelligent lock body to execute an unlocking action according to the unlocking instruction when the first key is determined to be correct according to the second key.
Specifically, after the intelligent lock body receives the ciphertext of the unlocking control signal, the ciphertext is decrypted to obtain a first secret key and an unlocking instruction, the first secret key and a second secret key are matched, for example, when the first secret key and the second secret key are consistent or complementary, if the first secret key and the second secret key are obtained, the correct first secret key is obtained, the unlocking action is executed according to the unlocking instruction, and if the first secret key is incorrect, the unlocking is refused, so that the vehicle battery is prevented from being stolen due to malicious unlocking, and the safety is improved.
According to the intelligent lock body control method provided by the embodiment of the invention, the unlocking instruction sender is subjected to identity verification and is encrypted by the encryption algorithm to generate the unlocking control signal, the intelligent lock body is controlled to execute the unlocking action according to the unlocking control signal, namely, data transmission is encrypted, so that the data security can be improved, and the intelligent lock body cannot be unlocked according to illegal unlocking data, so that the theft probability can be reduced, and the security is improved.
Further, in the embodiment of the invention, data between the intelligent lock body and the main control drive plate is encrypted and then transmitted in a ciphertext mode, so that the safety is improved. Specifically, after receiving an unlocking instruction, the main control drive board sends a request to the intelligent lock body, the intelligent lock body encrypts characteristic information such as chip identity information and user identification information and then uploads the encrypted characteristic information to the main control drive board, and the main control drive board acquires the chip identity information and the user identification code of the intelligent lock body; generating a first key according to the chip identity information and the user identification code and an encryption rule; and encrypting the first key and the unlocking instruction according to an encryption algorithm to generate an unlocking control signal carrying the first key and the unlocking instruction, and sending the unlocking control signal to the intelligent lock body as message data. The intelligent lock body generates a second secret key according to the chip identity information and the user identification code of the intelligent lock body, decrypts the plaintext of the message data of the unlocking control signal according to a corresponding decryption algorithm after receiving the message data of the unlocking control signal, obtains a first secret key and an unlocking instruction, identifies the first secret key, and identifies whether the first secret key is correct or not according to the second secret key; if the first secret key is matched with the second secret key, the first secret key is considered to be correct, the unlocking action is executed according to the unlocking instruction, namely, the unlocking action is executed according to the unlocking instruction only when the first secret key is correct. Because the feature information of each intelligent lock body is different, the first secret keys are different, and the data communication adopts ciphertext transmission, so that the safety of the intelligent lock body can be ensured.
In some embodiments, the plaintext message data transmitted by the main control drive board to the intelligent lock body comprises random numbers, namely variable and uncertain numerical values each time, so that different ciphertexts transmitted each time are ensured, the difficulty of cracking the message is increased, and the safety is further improved.
In some embodiments, the TEA encryption algorithm is used for encrypting the first key and the unlocking instruction, and ciphertext transmission is used, so that different keys can be used for the intelligent lock body and the main control drive plate, and the data security is improved. The TEA encryption algorithm is a block cipher algorithm, and the plaintext cipher text block is 64 bits, and the key length is 128 bits. The TEA algorithm uses an ever increasing Delta value as a change so that the encryption is different for each round, the number of iterations of the encryption algorithm can vary, and its reliability is guaranteed by the number of encryption rounds rather than the complexity of the algorithm. Therefore, the TEA encryption algorithm is simple in algorithm, strong in differential analysis resistance, high in encryption speed and high in safety, and accordingly the safety of data transmission can be improved.
Further, the intelligent lock body control method of the embodiment of the invention may further include: receiving firmware upgrading information of the intelligent lock body; and updating the user identification code and the encryption rule of the intelligent lock body according to the firmware upgrading information. Specifically, the intelligent lock body can periodically send a firmware upgrading request, the server sends firmware information corresponding to the intelligent lock body to the internet of things module of the corresponding vehicle after receiving the firmware upgrading request, or the server sends the firmware upgrading information to the internet of things module periodically, and then the internet of things module sends the firmware upgrading information to the main control drive board and the intelligent lock body, so that the firmware function of the intelligent lock body is upgraded remotely, the user identification code and the encryption rule of the intelligent lock body can be changed irregularly, and the safety is improved.
