Research on 3GPP LTE Security Architecture

With the improvement and maturity of 3G network, the wireless communication rate for the users has become more and more high. Every research institution will focus gradually shift to long term evolution Version (LTE) of 3G network. In this paper, 3GPP LTE security mechanisms are introduced in detailed; the security architecture of LTE/SAE is present; the key structure and domain security of the network are studied respectively.
