The present document is a study on the remote update of 3GPP long term secret keys held in a SIM / USIM. It:
  • Identifies which Long Term Keys should be updatable within this proposed feature.
  • Identifies the 3GPP/non 3GPP elements that would be affected by the update of these keys.
  • Identifies the Key Issues relating to the updating of long term keys.
  • Identifies potential requirements for the updating of long term keys.
  • Identifies the applicability of Long Term Key Updating to GSM, UMTS, LTE and 5G and how the requirements may change across these technologies.
  • Identifies solutions for the updating of long term keys.
  • Evaluates solutions for the updating of long term keys.
  • Concludes on the best solutions(s) for the updating of long term keys.
  • Makes recommendations for further work.
This study will consider existing and new solutions that can be used for the update of 3GPP Long Term Keys. The management of subscriptions is out of scope for this document.
