移动IPv6与移动IPv4的技术优势比较 总被引:4,自引:0,他引:4
IPv4在设计之初并没有考虑到终端设备的移动性,所以连网设备移动时需要从互联网上断开,而在另外一个地方重新连接时,还需要重新配置系统的新的IP地址、正确的子网掩码和新的默认路由器(网关)才能继续通信。为了支持互联网上的移动设备,IETF推出了移动IP 的标准来使用户保留不变的永久IP地址,而不管他们是否连接在网上。移动IP有两种:一种是基于IPv4的移动IPv4, 一种是基于IPv6的移动IPv6。 相似文献

Mobile IPv6 provides global mobility and location management support for the IPv6 network layer protocol. The design of Mobile IPv6 incorporates security features that differ significantly from its predecessor, Mobile IPv4. Some of the new security features are intended to counter new threats raised by route optimization, while others align Mobile IPv6 security more closely with basic IPv6 security mechanisms. In this paper, we outline the security threats to Mobile IPv6 and describe how the security features of the Mobile IPv6 protocol mitigate them. 相似文献

A comparative performance analysis on Hierarchical Mobile IPv6 and Proxy Mobile IPv6 总被引:1,自引:0,他引:1

This paper presents comparative results on Hierarchical Mobile IPv6 and Proxy Mobile IPv6. The two mobility support protocols
have similar hierarchical mobility management architectures but there are, however, clearly different perceptions: Hierarchical
Mobile IPv6 has specific properties of a host-based mobility support protocol, whereas Proxy Mobile IPv6 is based on a network-based
mobility support protocol. Thus, it is important to reveal their mobility characteristics and performance impact factors.
In this paper, a cost based evaluation model is developed that evaluates the location update cost, the packet delivery cost,
and the wireless power consumption cost based on the protocol operations used. Then, the numerical results are presented in
where impacts of the various system parameters are evaluated. The results demonstrate that Proxy Mobile IPv6 always outperforms
Hierarchical Mobile IPv6 due to its ability to avoid the mobility signaling sent by the mobile host, and its reduced tunneling
overhead during communications with other nodes. 相似文献

In the Mobile IPv6 (MIPv6) protocol, a mobile node (MN) is a mobile device with a permanent home address (HoA) on its home link. The MN will acquire a care‐of address (CoA) when it roams into a foreign link. It then sends a binding update (BU) message to the home agent (HA) and the correspondent node (CN) to inform them of its current CoA so that future data packets destined for its HoA will be forwarded to the CoA. The BU message, however, is vulnerable to different types of security attacks, such as the man‐in‐the‐middle attack, the session hijacking attack, and the denial‐of‐service attack. The current security protocols in MIPv6 are not able to effectively protect the BU message against these attacks. The private‐key‐based BU (PKBU) protocol is proposed in this research to overcome the shortcomings of some existing MIPv6 protocols. PKBU incorporates a method to assert the address ownership of the MN, thus allowing the CN to validate that the MN is not a malicious node. The results obtained show that it addresses the security requirements while being able to check the address ownership of the MN. PKBU also incorporates a method to verify the reachability of the MN. 相似文献

移动IPv6通过移动节点(MN)家乡地址绑定注册实现对移动性的支持,MN向家乡代理的注册必须提供家乡地址、家乡代理地址和家乡代理安全关联,移动IPv6基本协议假设以上信息总是存在于MN之上,并未考虑实际部署中的复杂情况。文中重点分析了该问题,把MN动态获得家乡代理注册信息的过程定义为Bootstrapping,考虑了MN在不同网络部署情况下的Bootstrapping,给出了一种可能的解决思路。 相似文献
