Specifically, after the asymmetric key pair is generated by the back panel controller U2, the public key of the asymmetric key pair may be sent to the front panel controller U1 through a controller area network (e.g., CAN bus), as specifically indicated by "1" and "2" in fig. 2. After the front panel controller U1 encrypts the first communication information sent by the door external module (for example, the communication information transmitted by the first peripheral module through the UART or the communication information transmitted by the first other peripheral module through the bi-directional two-wire system synchronous serial bus I2C) by using the public key, the encrypted result is sent to the rear panel controller U2 through the CAN bus, as shown in fig. 2 as "3" and "4". The front panel controller U1 and the rear panel controller U2 are connected by a CAN bus, as shown in fig. 3.
Specifically, the specific time may be understood as the time when the smart door lock is restored to the factory setting, or the time when the smart door lock updates the asymmetric key pair based on the user instruction. The asymmetric key pair generated by the rear panel controller at a specific time can comprise a private key stored in the rear panel controller and a public key sent to the front panel controller through a controller local area network, so that the front panel controller encrypts communication data of the outdoor module through the public key in a time other than the specific time, and decrypts the encrypted communication data transmitted by the rear panel through the public key; the back panel controller encrypts the communication data of the indoor internal module by the private key in the time except the specific time, and decrypts the encrypted communication data returned by the front panel controller by the private key; and no key negotiation is performed any more in a time except the specific time so as to prevent the using process from being hijacked.
Specifically, the first communication information may be communication information such as fingerprint information, face information, radar information, and the like, and the type of the communication information is mainly related to the type of the outdoor module, for example, when the outdoor module is a fingerprint identification unit, the communication information is fingerprint information; when the door outer module is a face recognition unit, the communication information is face information.

According to the anti-interference method for the intelligent door lock, the encryption and decryption are carried out through the asymmetric public key and the asymmetric private key, the first communication information is encrypted through the public key, and the first encrypted data is decrypted through the private key, so that the embodiment can ensure that the user information is not acquired by other people, and the information safety is ensured; data transmission is carried out through a controller local area network, the anti-jamming capability of signals can be effectively improved, and therefore the problem that the intelligent door lock in the prior art is poor in signal anti-jamming capability is solved.
Preferably, the method further comprises the steps of:
s300: when second communication information sent by the in-door module is received, the second communication information is encrypted by using the private key, and second encrypted data are sent to the front panel controller through the controller local area network, so that the front panel controller decrypts the second encrypted data according to the public key and transmits the second decrypted data to the out-door module.
Specifically, when an in-door user communicates communication information to the outside of the door through the in-door module, the rear panel controller may encrypt, by using a private key, second communication information (for example, communication information transmitted by the second peripheral module through the UART or communication information transmitted by the second other peripheral module through the bidirectional two-wire system synchronous serial bus I2C) sent by the in-door module, and then send the encrypted result of the encryption device to the front panel controller through the CAN bus, as shown in "4" and "3" in fig. 2; the front panel controller can decrypt the encrypted result according to the public key after receiving the encrypted result, and sends the decrypted second decrypted data to the outdoor module so that the outdoor user can acquire the second communication information in the second decrypted data.
According to the anti-interference method for the intelligent door lock, the encryption and decryption are carried out through the asymmetric public key and the asymmetric private key, the second communication information is encrypted through the private key, and the second encrypted data is decrypted through the public key, so that the embodiment can ensure that the user information is not acquired by other people, and the information safety is ensured; data transmission is carried out through a controller local area network, the anti-jamming capability of signals can be effectively improved, and therefore the problem that the intelligent door lock in the prior art is poor in signal anti-jamming capability is solved.
