scope:

The present document defines communication security processes designed for very low throughput Machine Type Communication (MTC) devices that are battery constrained. These processes consist of:

- A Key agreement service for End to Middle and End to End security use

- An End to Middle secure transport service that includes the ability to verify and confidentiality protect low throughput data.

- An End to End secure transport service that includes the ability to verify and confidentiality protect low throughput data.
