摘要：
A user equipment (UE) device that is able to engage in multiple security contexts contains a key generator to generate one or more authentication keys for authentication of the UE device in a particular security context and a component configured to facilitate storing of the authentication keys in a subscriber identity module (SIM) if an elementary file (EF) structure for the particular security context is available in the SIM and to facilitate storing of the authentication keys in a nonvolatile memory (NVM) of the UE device if the EF structure is not found in the SIM.
