LTE/LTE-A网络中针对MTC在移动环境下的群组认证协议研究

As one of most important communication techniques for future wireless communications, Machine Type Communication (MTC) has attracted more and more attention. Due to its data communication and network services, MTC has quickly become the driving force of the mobile operators for a large number of real-time network applications. However, there are still many open challenges for the practical enforcement of the MTC security as the introduction of MTC into 3GPP remains in its early stage of the development. The design of the MTC security mechanisms in the mobile environments of the LTE/LTE-A networks will be the major point of the future research for the LTE/LTE-A security. To cope with these problems, we start our work by analyzing the different mobility requirements of MTC devices. Based on several characters of MTC devices, such as restricted resources, infrequent connection, several different types, large amounts and so on, we aim to break some technical difficulties of MTC security issues in the mobile environments of the LTE/LTE-A networks, including energy optimization group-based access authentication and key agreement mechanisms for environment with low mobility, efficient group-based anonymity handover authentication protocol for environment with high mobility, as well as the fast and secure Mobile Relay Node (MRN)–based handover authentication protocol for a lot of MTC devices in high speed mobile equipments. We aim to fill the gaps in related fields and provide technical support and protection for the implementation of secure and efficient MTC mobile services.

MTC作为未来通信中最重要的无线通信技术之一已经受到越来越多的关注。MTC的数据通信及其所带来的网络服务，使得它已经成为移动运营商争夺的下一个亿级规模的应用市场。然而，国内外MTC通信及其安全技术的研究目前刚刚起步，尤其是3GPP中关于MTC安全的国际标准的制定尚处于规划中。LTE/LTE-A网络移动场景下的MTC安全是一个亟待解决的重要问题。针对这个问题，本项目从LTE/LTE-A网络下MTC终端的不同移动需求出发，结合MTC终端能量有限、非频繁接入、类型多样化、数量巨大等特征，重点研究了LTE/LTE-A网络中针对低移动场景下能耗优化的MTC终端群组接入认证和密钥协商协议，针对高移动场景下的高效安全的匿名群组切换认证协议以及基于移动中继节点构造的高速移动装置内大量MTC终端群组快速安全切换协议。本项目旨在填补相关领域的空白，为MTC移动业务安全、有效地开展提供技术上的支撑和保障。
