The Research And Implementation Of Secure Network Model Based On IPv6

In information, networking highly developed today, a new generation of network technology innovation, with the Internet development, the current network protocol IPv4 revealed shortcomings such as growing number of IPv4 addresses in the space, the network security, which led to the raise of IPv6 protocol and its further development. IPv6 replaces IPv4 has become the inevitable trend of development. IPSec network security protocol is the security standard of IPv6, whether the IPSec correct implementation relates to the entire IPv6 network security.Through the discussion of IPSec especially the IKE process, this article analyzes its weakness, introducing trusted-third-party mechanism, cooperating with the IPv6 the extension header mechanism, proposed a security network model based on the IPv6 network environment through the trusted-third-party server management. In detail introduced this security network model structure and the establishment process of entire connection, with emphasis to the improvement of IKE negotiation process, and proposed an effective realization plan. Finally carries on the analysis and the summary of deficiency to it.
