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