The invention discloses a message authentication method. The method comprises the steps of: receiving a message producing/consuming request sent by a message producing/consuming client side; extracting the IP address of the message producing/consuming client side and Topic names request for producing/consuming from the message producing/consuming request; querying the pre-stored corresponding relationship between the Topic names and the IP address set of a legal producing/consuming client side, so that the IP address set, corresponding to the extracted Topic names, of the legal producing/consuming client side is obtained, wherein different Topic names are used for identifying different services; judging whether the extracted IP address of the message producing/consuming client side existsin the IP address set of the legal producing/consuming client side or not; and if yes, determining that message authentication of the message producing/consuming client side is passed. The invention further discloses a message authentication device, a message authentication system and a computer-readable storage medium. By means of the message authentication method, the message authentication device, the message authentication system and the computer-readable storage medium in the invention, precise distribution of services can be realized.
