This TR studies the security aspects of System Improvements for Machine Type Communication. In
particular, the goals of the present document are:
To identify and analyze the threats to the MTC system within the scope of the service requirements, functionality
and use cases as specified in TS 22.368.
To identify possible security and privacy impacts induced by the system architecture improvement for machine
type communications based on TR 23.887 and TS 23.682.
To determine possible security requirements based on the analysis above and describe the possible solutions to
meet those requirements.
Machine-type communication aspects of (x)SIMs and/or new models for the management of (x)SIM are out of scope of
the present document.
