A secure mobile-IPv6 network model

Mobile-IPv6 technology brings us convenient but also produces a series of security issues. Virtual private networks allow two or more parties to communicate securely over a public network. VPNs provide the assurance such as confidentiality, host authentication and data integrity by using cryptographic algorithms and protocols. In this article the concepts of mobile IP was introduced and the security problem was analyzed. A VPN implemented with the IP Security Protocol (IPSec) is presented to protect the communication between Mobile Node and Home Agent. According to special demands of mobile network, a secure mobile-IPv6 network model is presented based on IPSec. With this kind of model the high security and reliability can be achieved.
