Method and device for authenticating BMP (Monitoring Protocol) message

The invention provides a method and device for authenticating a BMP (Monitoring Protocol) message. The method applied to a sending end comprises the steps of determining unique first check information according to a first check algorithm and a first key pre-configured to the sending end, and a to-be-sent first message, wherein BMP data information is packaged in the first message; and storing the first check information in the first message, sending the first message to a receiving end, and checking the received first message by the receiving end according to a second check algorithm and a second key, wherein the second check algorithm and the first check algorithm are the same algorithm, and the second key and the first key are the same key. According to the method for authenticating the BMP message provided by the invention, the security authentication is carried out at two ends of a BMP session, and the communication security of the BMP can be effectively ensured. 本发明提供了种BMP报文认证的方法及装置，应用于发送端的所述方法包括：根据发送端预先
