摘要
进一步发展Internet业务需要增大带宽并且要有移动性,因此IP网与卫星网结合成了热门话题。卫星通信中,其天然的广播特性以及全球无所不在的覆盖能力和IP网本身固有的很多安全隐患,使其安全问题尤显突出,在卫星IP网的性能增强型网关PEP中应用IPSec,从而构成PEP-IPSec,这样一方面提高了TCP/IP在卫星IP网上的性能;另一方面也极大地增强了卫星IP网的网络安全。
The satellite communication has the advantage of the broadcast and ubiquitous coverage of the world, however this advantage has caused many security problems, what＇ s more, the terrestrial IP network also has many inherent security issues, so the satellite IP network makes this problem more serious. There is a possible solution to alleviate this security problem if we utilize IPSec technique into the performance enhancing proxy （PEP） of the satellite IP networks. On one hand,it increases the performance of the TCP/IP traffic on satellite IP networks, On the other hand it strengthen the satellite IP network＇ s security.
