Abstract
Method and Apparatus for Securing a Connection in a Communications Network A method of operating a user equipment (UE) using a Generic Bootstrapping Architecture (GBA) is provided. The method includes establishing a shared secret between the UE and a Network Application Function (NAF). An authentication request is sent to a Bootstrapping Server Function (BSF) by the UE. An original parameter intended for a key derivation function and a bootstrapping transaction identifier is received from the BSF. An application request, including the bootstrapping transaction identifier, is sent by the UE to the NAF. A modified parameter is derived by the UE from the secret and the original parameter intended for the key derivation function. A cryptographic key is determined using said modified parameter in place of or in addition to the original parameter in the key derivation function, and communications with the NAF are secured using the key.
