摘要： A method, system and apparatus for protecting a bootstrapping service function (BSF) entity from attack includes: a first temporary identity and a second temporary identity are generated after a BSF entity performs a mutual authentication with a user equipment (UE) by using an initial temporary identity sent from the UE; the BSF entity receives a re-authentication request carrying the first temporary identity from the UE; and the UE sends a service request carrying the second temporary identity to a network application function (NAF) entity. The present disclosure prevents attackers from intercepting the temporary identity at the Ua interface and using the temporary identity to originate a re-authentication request at the Ub interface, thus protecting the BSF entity from attack and avoiding unnecessary load on the BSF entity and saving resources.
