To prevent such credential forwarding attacks, modern authentication protocols rely on channel bindings. For example, WAMP-cryptosign can use the tls-unique channel identifier provided by the TLS layer to strongly bind authentication credentials to the underlying channel, so that a credential received on one TLS channel cannot be forwarded on another. )z tls-uniquezinvalid channel ID type {}Ú_tlsConnectionN) Ú ExceptionrÚhasattrrÚget_peer_finishedÚ get_finishedÚhashlibÚsha256ÚupdateÚdigest)Ú transportÚ is_serverÚchannel_id_typeÚtls_finished_msgÚmrrrr ^s     r )N)Ú __future__rr Útwisted.internet.deferrÚtwisted.internet.addressrrÚtwisted.internet.stdiorÚ ImportErrorÚtyperrÚ__allrr r rrrrÚs&    þ  ÿ
