The study on secure auto-configuration technology in IPv6

According as computer is supplied in a lot of homes and offices and Internet use increases, various service based on the Internet. Including wireless PDA in the future, many devices such as Internet telephone, TV, refrigerator and oven will be connected on the Internet and Internet address exhaustion will be raised to serious problem gradually. Present IPv4 address exhaustion problem is solving through NAT (Network Address Translation) and the transition to next Generation Internet is accelerated because of advantage that can offer various function of mobility security service, QoS as well as solution of IPv4's address exhaustion. In IPv6 all hosts are designed to create and sets their address automatically without manager's intervention using Neighbor Discovery Protocol. But, when IPv6 host sets its address automatically, there are serious security vulnerabilities. To solve this security problem, many people have researched about secure auto-configuration. In this paper, we analysis security vulnerabilities in auto-configuration and provide security requirements for secure auto-configuration.
