摘要：
In one embodiment, a scheme is provided for securing a personalized indicium assigned to a mobile communications device (116). Upon detecting at a network node (502) that an address associated with the mobile communications device (116) has changed, a challenge-and-response procedure (516, 518) is negotiated between the mobile communications device (116) and the network node (502) for authenticating the personalized indicium using a shared authentication key.
