Title:
CONTROL METHOD FOR SMART HOME DEVICES AND MEDIUM AND TERMINAL THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/121125
Kind Code:
A1
Abstract:
A control method for smart home devices (103-1, ..., 103-n) and a medium and a terminal thereof, which relate to the field of the Internet of Things. The method comprises: a first client (101-1) uses a first key to encrypt a control instruction for controlling the smart home devices (103-1, ..., 103-n), generates control instruction ciphertext, and generates first ciphertext check information on the basis of a service protection code, and the first client (101-1) sends the generated control instruction ciphertext and first ciphertext check information; the control method uses the key of a symmetric algorithm to encrypt the control instruction for controlling the smart home devices (103-1, ..., 103-n), and at the same time, uses the service protection code identifying a legal identity of a user to ensure the security of instruction transmission. Compared to asymmetric encryption algorithms, the volume of calculation for encryption and decryption is small, which is suitable for smart home devices where a public key and a private key required by asymmetric encryption algorithms cannot be deployed due to hardware limitations.
