Message communication method, and device

A message communication method, wherein the method comprises:

• receiving a target message from an electronic device;
• obtaining plaintext content and a target authentication code from the target message;
• generating at least one second message authentication code based on a message receiving time of the target message, preset message transmission duration, the plaintext content, and a first key corresponding to the electronic device;
• and
• determining, based on the target authentication code and the at least one second message authentication code, that checking on the target message succeeds, and performing a response action corresponding to the plaintext content.

An electronic device, comprising:

• one or more processors;
• and
• a non-transitory computer readable medium which contains computer-executable instructions that, when executed by the one or more processors, cause the electronic device to perform operations comprising:
• determining, in response to a first operation, a first message authentication code based on a message sending time corresponding to the first operation, plaintext content corresponding to the first operation, and a first key corresponding to the electronic device;
• processing the first message authentication code based on a target authentication code length, to obtain a target authentication code;
• and
• generating a target message based on the target authentication code and encrypted plaintext content, and sending the target message to a server.

A server, comprising comprising:

• one or more processors;
• and
• a non-transitory computer readable medium which contains computer-executable instructions that, when executed by the one or more processors, cause the server to perform operations comprising:
• receiving a target message sent by an electronic device;
• obtaining plaintext content and a target authentication code from the target message;
• generating at least one second message authentication code based on a message receiving time of the target message, preset message transmission duration, the plaintext content, and a first key corresponding to the electronic device;
• and
• determining, based on the target authentication code and the at least one second message authentication code, that checking on the target message succeeds, and performing a response action corresponding to the plaintext content.
