Methods and systems for operating a secure mobile device

摘要

The invention assumes a system wherein a key at a machine type communications (MTC) user equipment (UE) has been derived using generic bootstrapping architecture (GBA). In one claim this key is used to protect another key, preferably a public key, which is used to verify some protected data. In another claim one interface is used to derive the GBA key and another interface is used to transmit the GBA key or a key protected by the GBA key. In another claim two devices obtain two key data using GBA and a server respectively and then securely associate using the key data. In another claim a machine to machine (M2M) device derives a GBA key and uses it to verify received data.
