一种新的异构无线网络安全体系结构

摘要

随着无线通信和网络技术的高速发展和广泛应用，异构无线网络逐渐受到越来越多的关注。而异构无线网络不仅面临现有各种无线网络的安全问题，也面临着异构互联所带来的新的安全问题。论文在介绍和分析现有无线网络的安全结构和安全机制的基础上，提出了一种分层的异构无线网络安全体系结构，并引入了新的安全实体。分析表明，该结构能很好地适应异构无线网络的特点，对未来的网络融合和体系结构研究具有指导意义。%With the rapid development and extensive application of wireless communication and network technology , heterogeneous network has attracted more and more attentions .However ,heterogeneous wireless network has security prob‐lems not only existing in wireless network but also caused by heterogeneous interconnection .The security architecture and security mechanism of the traditional wireless network are analyzed ,and a new security architecture of heterogeneous wire‐less network to which some security entities are added is presented .Analysis shows that the architecture can satisfy the char‐acteristics of the heterogeneous wireless network and have significance in the research of network convergence and system ar‐chitecture of the heterogeneous wireless network in the future .
