| 摘 要： | 移动IP使得移动主机在不同网络间不断移动过程中仍能保持正常的通信,而不需要重新建立TCP连接。当一个移动节点在外地链路时,为了和家乡代理或家乡链路通信,一般需要通过家乡的防火墙,目前有两种方案通过防火墙,一是SKIP,另一个是ISAKMP/Oakley,但是这两个方案一般都假设移动节点在外地链路的“公共”部分,也就是说移动节点在外地链路的防火墙以外,而在很多情况下则不同,论文试就移动节点在外地链路的“私有”部分时如何与家乡链路安全通信进行讨论。

| Abstract: | Mobile IP allows a mobile node to maintain any ongoing communications without reestablishment of a TCP connection when it moves from a network to another.When a mobile node roams in foreign network,commonly it needs to traverse its home firewall in order to communicate with home agent or home network.Today,there are two schemes that can traverse firewall,one is SKIP,the other is ISAKMP/Oakley.But the two suppose that the mobile node is at the"public"part,that is to say the mobile node is outside the foreign firewall. Moreover,most of the things are difference. This paper will discuss how a mobile node has a security communication with its home network when it is at the"private"part of a foreign network. |
