Abstract

The invention relates to an end-to-end communication encryption method, a storage medium and terminal equipment, and the method comprises the steps that a user side receives first negotiation information sent by gateway equipment, and the first negotiation information comprises a gateway public key configured by the gateway equipment; the user side determines a user shared key corresponding to the user side based on the gateway public key and a user private key configured by the user side; and the user side encrypts to-be-transmitted communication data based on the user shared key, and sends the encrypted communication data to the gateway device. A shared key is generated through negotiation between a user side and gateway equipment, bidirectional authentication is performed on the user side and the gateway equipment, and the user side encrypts communication data to be transmitted by using the shared key, so that end-to-end encrypted communication between the user side and the gateway equipment is realized. As the encryption key is generated by direct negotiation of the two ends, communication data of the two ends cannot be analyzed by equipment except the user side and the gateway equipment.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an end-to-end communication encryption method, device, storage medium and terminal device. Background technique [0002] Existing smart home systems generally use encryption authentication between home devices and the cloud platform, and encryption authentication between users and the cloud platform. The key of the cloud platform is the same for all devices or the same type of device. Therefore, if a security incident occurs on the cloud platform, it will affect many users and devices. [0003] Therefore, how to improve the security of smart home system communication is an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide an end-to-end communication encryption method, device, storage medium and terminal device, aiming to solve the ...
