Abstract
The present disclosure provides a secure communication method, and the method may include: a sending terminal may generate data to be transmitted and determine encrypted data by encrypting the data to be transmitted using a preset encryption algorithm based on an encryption key. The encryption key may be obtained by a key exchange process between a smart door lock and a mobile terminal through a preset secure communication channel. The sending terminal may assign a unique identifier to the encrypted data and may send the encrypted data with a unique identifier to the receiving terminal, so that the receiving terminal may perform identity authentication on the encrypted data with the unique identifier and may decrypt the encrypted data based on the encryption key obtained by the key exchange process according to a result of the identity authentication.
