Description
Technical field
The present invention relates to the communications field, the method for the intercommunication of especially a kind of identity position separation network and the Internet and intercommunication network.
Background technology
Along with the development of information technology, be that the information network of representative serves more and more important effect in economy and social development with the Internet.But the Internet also in use exposes increasing problem.At the beginning of the Internet design, only considered fixing terminal trusty, not support terminal mobility, also there is no inherent Security Assurance Mechanism.Along with the development of the wireless technology such as 3G, rear 3G, 4G, the support of the Internet to mobile terminal becomes more and more urgent problem.Meanwhile, along with the expansion of internet, applications scope, safety problem is also more outstanding, and these problems have been difficult to solve under existing Internet technology framework.
ICP/IP protocol is the basis of the Internet.IP address has the double attribute of identity, position, is that ambulant root cannot be supported in the Internet.As the identity attribute of terminal, IP address can not change in fast mobile terminal process, otherwise the upper-layer service connections such as TCP, UDP can be interrupted along with the change of address; As the position attribution of terminal, IP address must change in fast mobile terminal process (address must have the subnet prefix at current place), otherwise router correctly cannot be forwarded to terminal packet.Meanwhile, the double attribute of IP address is also that the fail safe of the Internet can not get the basic reason place solved.Because IP address must comprise the position attribution of terminal, so mobile terminal cannot be assigned to fixing IP address, the identity of the assailants such as hacker therefore cannot be determined on the internet according to IP address.This is that on current internet, the safety problem such as attack, swindle, abuse can not get the basic reason solved.
