Abstract
A SIM provider apparatus is disclosed that is configured to generate a first service provider key (SPK) based on master attributes at the SIM provider apparatus. The master attributes, including a master key, are shared by both the SIM provider apparatus and a SIM container. The SIM provider apparatus is further configured to verify a second SPK, received from the SIM container and generated based on the master attributes in the SIM container, is the same as the first SPK. The SIM provider apparatus then stores the first SPK in response to the first SPK being the same as the second SPK.
