Research and Implementation of IPSEC Based on TD-LTE System

With the rapid development of Internet technology, network and information security has become increasingly important. After studying the principle of IPSEC(IP Security) and VPN (Virtual Private Network) technology, this paper designs a network architecture which is called S1 in the TD-LTE communication system. The specific packet is securely encrypted by using IPSEC technology between the base station and security gateway. After a lot of tests, the technical solution to achieve IPSEC is proved to be realized and to have a highly efficient and stable characteristic.
