Method for unlocking intelligent lock, mobile terminal, intelligent lock and server
View Patent ↗Provided are a method for unlocking an intelligent lock, a mobile terminal, an intelligent lock and a server. The method includes following steps. A mobile terminal receives an initial key and a communication key from a server. The mobile terminal encrypts the initial key and preset key data by using the communication key to generate an unlocking verification code. The mobile terminal attaches the preset key data to the unlocking verification code, to obtain an unlocking verification code attached with the preset key data. The mobile terminal sends the unlocking verification code attached with the preset key data to the intelligent lock. The intelligent lock performs an unlocking operation based on the unlocking verification code attached with the preset key data.
1. A method for unlocking an intelligent lock, comprising:
receiving, by a mobile terminal, an initial key and a communication key from a server;
encrypting, by the mobile terminal, the initial key and preset key data by using the communication key to generate an unlocking verification code;
attaching, by the mobile terminal, the preset key data to the unlocking verification code, to obtain an unlocking verification code attached with the preset key data; and
sending, by the mobile terminal, the unlocking verification code attached with the preset key data to the intelligent lock, wherein the intelligent lock performs an unlocking operation based on the unlocking verification code attached with the preset key data.
2. The method according to claim 1 , wherein the preset key data is a timestamp.
3. The method according to claim 1 , wherein the mobile terminal is provided with an up counter corresponding to the initial key, and the preset key data is a count value of the up counter, the count value of the up counter is incremented by one in response to the mobile terminal receiving the initial key and the communication key from the server.
4. The method according to claim 1 , before the mobile terminal sends the unlocking verification code attached with the preset key data to the intelligent lock, further comprising:
establishing, by the mobile terminal, a connection with the intelligent lock in a wireless communication manner of Bluetooth, zigbee or Wireless Fidelity (WIFI).
5. A mobile terminal, comprising:
a processor; and
a memory storing program instructions, when executed by the processor, causing the processor to perform the method for unlocking the intelligent lock according to claim 1 .
