Method based on border gateway protocol message for controlling messages security protection

摘要

The present invention discloses a method based on Border Gateway Protocol message for controlling message security protection, the method comprises the communicating process of the authentication mechanism and the authentication word between the message sending side and the message receiving side. If the communicating is successful, the message receiving side will authenticate the 16-byte tag field in the BGP message head of the message sent by the message-sending side according to the authentication mechanism and the authentication word; after the BGP connection is established, the message-sending side will send a BGP message according to the former 16-byte tag field in the message head determined by the authentication mechanism and the authentication word, the message receiving side authenticates the received BGP message according to the determined former 16-byte tag field in the BGP message head, if it pass the authentication, the message will be received, otherwise the message will be abandoned; through said scheme, the BGP message head can be encrypted, even though the BGP message is intercepted illegally, the content is unavailable, and BGP session and the whole network will not be attacked according to content of the BGP message.
