Ipv6 Network Security Technology Research

The article first introduced the IPv6 network related background and the technology, and have analyzed the security agreement and the IPSec security ability, the security system constitution of IPv6; And detail introduced IPSec basic agreement authentication expansion text of a telegram (AH) and safe seal load text of a telegram (ESP); The system other parts of IPv6 security, example, the security policy,the encryption and the authentication algorithm, the key management and so on, the article discussed how them to work, they match each other to protect the IPv6 network of security. And analyzed current IPv6 network existence some loopholes and the flaw, as well as some traditional security tools under IPv6 improvement, has simultaneously introduced the safe audit and the risk analysis theory constructs in the next generation network dynamic security model; Finally has carried on the analysis to the IPv6 firewall realization protection network security, has produced in the firewall in a realization protection module, had to the firewall in IPv6 network protective measure had further understood. The article conclusion has carried on the forecast to the IPv6 development, and some questions which needs to improve to the next generation network in have carried on the induction summary, explained the research goal and the harvest, it was clear about the constructed the new security model for the next generation security extremely importantly to send the significance.
