The study on secure auto-configuration technology in IPv6

As computers supplied in a homes, offices, and Internet use increases, various service based on the Internet are developed. In the future, many devices such as wireless PDA, Internet telephone, TV, refrigerator and oven will be connected on the Internet and the Internet address exhaustion problem is gradually raised. The present IPv4 address exhaustion problem is being solved through NAT (network address translation) and the transition to next generation Internet is accelerated because of the advantages offered in various functions of mobility security service, QoS, as well as solutions for IPv4´s address exhaustion. In IPv6, all hosts are designed to create and set their address automatically without the manager´s intervention using the neighbor discovery protocol. When IPv6 host sets its address automatically, there are serious security vulnerabilities. To solve this security problem, many people have researched about a secure auto-configuration. In this paper, we analyze the security vulnerabilities in auto-configuration and provide security requirements for secure auto-configuration
