Abstract As emergence of several access methods, many LANs use access of dynamic IP address. Virtual Private Network(VPN)of static configuration is not applicable. Thus, how to exchange information, construct VPN in dynamic network is indicated as new question for research. A secure and dynamic tunneling mechanism is presented. And message of this mechanism is defined. This mechanism can solve above mentioned issue. Authentication and anti-replay function are introduced to avoid secure problems. The result of experiment shows that this mechanism can construct VPN securely and efficiently in dynamic network.
