There is already a option in the BGP OPEN message to add authentication on
a BGP session.  However, the RFC doesn't specify an authenitcation method
to use.  Of course securing the level 4 BGP session without securing the
underlying TCP session is a weakness, so there is a proposal to implement
an MD5 TCP authentication method.  Does anyone know the status of this
