Original Abstract Submitted

This application provides a message communication method and a device. In one example method, an electronic device determines, 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. The electronic device processes the first message authentication code based on a target authentication code length, to obtain a target authentication code. The electronic device generates a target message based on the target authentication code and encrypted plaintext content, and sends the target message to a server.
