Study on battery efficient security for very low throughput Machine Type Communication (MTC) devices
The present document's objectives are to:
a) Investigate whether battery efficient 'device to enterprise' mechanisms to provide sufficient security exist.
b) Investigate potential enhancements to 3GPP's security architecture(s) that enable the Home Operator to be able to offer well guaranteed security to enterprises e.g. to provide security between the UE and a node in the home operator domain.
c) Both S1 and Gb based architectures should be considered when undertaking b, above.
The impacts of relevant authentication and key agreement procedures are also presented.
The following should be taken into account for the study:
- The potential solutions should aim at minimising the energy consumption of devices to help meet the objective of a ten year battery life in the extended coverage situation and take into consideration the very low data rate capability of the radio interface when using the Energy Consumption Evaluation Methodology described in TR 45.820.
