0  Introductionp. 8

This document collects the identified threats and proposed countermeasures, and includes the design choices and rationale for why proposed security mechanisms are accepted or rejected to record the history of the final security solution.

1  Scopep. 8

The scope of this 3GPP Technical Report is rationale and track of security decisions in Long Term Evolved (LTE) RAN and 3GPP System Architecture Evolution (SAE) for release 8.
Disclaimer: This TR reflects the discussions held in 3GPP SA3 while 3GPP SA3 was working towards TS 33.401. This TR is useful to better understand the basis on which decisions in TS 33.401 were taken, and the alternatives that were discussed towards the decision. Some of the text in this TR reflected 3GPP SA3's decision. However 3GPP's position on EPS Security Architecture is reflected in the normative text in TS 33.401.
