Abstract
To facilitate a change in network authentication key (Ki) for use by a smart card (SIM) during authentication on a cellular telecommunications network, there is provided a smart card management scheme that combines key derivation with over the air (OTA) provisioning. This scheme ensures both that the Ki is never transmitted OTA and that the Ki is stored in two locations only: on the SIM and at an authentication center (AuC).
