MESSAGE COMMUNICATION METHOD AND DEVICE

Provided in the present application are a message communication method and device. In the method, in response to a first operation, an electronic device determines a first information authentication code according to 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 information authentication code according to the length of a target authentication code to obtain the target authentication code; and the electronic device generates a target message according to the target authentication code and encrypted plaintext content, and sends the target message to a server. In the solution, after generating the first information authentication code, the electronic device can process the first information authentication code according to the length of the target authentication code to obtain the target authentication code. The target authentication code can be
