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.

A method for preserving privacy during authorization in pervasive environments is described. The method includes an authorization phase in which the user is provided with a reusable credential associated with verifiable constraints, and an operation phase where the service provider verifies the reusable credential before authorizing the user. Third parties cannot link plural uses of the credential to each other, and the service provider cannot link plural uses of said credential to each other.
