LTE; 5G; Battery Efficient Security for very low throughput Machine Type Communication (MTC) devices (BEST) (V15.4.0; 3GPP TS 33.163 version 15.4.0 Release 15)
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.
