A method, device and system for message processing are disclosed. A first node receives a first message sent from relay equipment; the first message comprises data in a second message sent from a second node to the relay equipment; the data in the second message is encrypted using second additional authentication data and a session key between the first node and the second node; according to at least address information in a header of the second message, the second additional authentication data is generated by the second node using a second rule; according to address information in a header of the first message, first additional authentication data is generated by the first node using a first rule; and the data in the first message is decrypted using the first additional authentication data and the session key between the first node and the second node. Resolved is the problem of channel utilization reduction, which is caused by the decryption and re-encryption processing needed in existing relay equipment when forwarding a message between a station and an access point. |
