SECURE COMMUNICATION METHOD BASED ON SMART DOOR LOCK SYSTEM AND SMART DOOR LOCK SYSTEM THEREOF

WIPO Patent Application WO/2018/177188

A1

Provided is a secure communication method based on a smart door lock system, the smart door lock system comprising a smart door lock and a mobile terminal. The method comprises: a sending end generating data to be transmitted and encrypting the data by using a preset encryption algorithm via an encryption key to obtain encrypted data (103), the encryption key being obtained through connection and exchange between the smart door lock and the mobile terminal via a preset secure communication channel (102); the sending end configuring a unique identifier for the encrypted data (104); sending encrypted data with the unique identifier to a receiving end (105), such that the receiving end authenticates the encrypted data with the unique identifier (106); and processing, according to an authentication result, the encrypted data by means of the encryption key obtained through exchange (107). In the method, since a server does not save any key, the server cannot understand data forwarded by itself, such that data encryption, identity authentication, and anti-replay and anti-tamper functions in the communication between the smart door lock and the mobile terminal are still effective even if the server is broken, thereby ensuring data security.
