IPSEC PACKAGING SECURITY MECHANISM IN 4G/LTE MOBILE COMMUNICATION NETWORKS

Abstract

Today, security issue in mobile communication networks in the world as well as in Vietnam is a very important issue. Therefore, network security and remediation solutions are essential. In the ways of network protection, IP Security becomes an effective solution to help secure the packets transmitted in the mobile communication network. The article presents problems and methods related to IP Security protocol, and introduce IP Security mechanism in 4G/LTE mobile communication network and provide security simulation methods packets using IP Security. IP Security protocol and application of IP Security mechanism protect the network domain control plane, and the user plane at the backhaul link in the 4G/LTE mobile communication network. From the obtained researches, the article shows how it works when transmitting packets secured by IP Security protocol in 4G/LTE networks.
