The Research on Mobile IPv6 Security Features Feng Xiaorong Software Quality Testing Engineering Research Center, China Electronic Product Reliability and Environmental Testing Research Institute, Guangzhou, Guangdong, 510610, China Email: fengxr@ceprei.com Lin Jun, Jia Shizhun Software Quality Testing Engineering Research Center, China Electronic Product Reliability and Environmental Testing Research Institute, Guangzhou, Guangdong, 510610, China Abstract—along with the rapid progress and widely application of mobile network, mobile IPv6 security has become an important issue. By analyzing new features of mobile IPv6, the paper describes potential security threats hidden in protocol implementation, illustrates the principle of new security attacks and put forward corresponding preventive measures and technical solutions. New strategies including return to routing process, address validation and IPsec mechanism are proposed to satisfy mobile IPv6 security requirements.

INTRODUCTION The rapid growth of intelligent mobile terminal users and fast development of Next Generation Network (NGN) have greatly promoted intelligent mobile terminal applications. With remarkable progress of its application, Internet protocol version 4 (IPv4) cannot satisfy special requirements of mobile Internet, such as security and network performance. At present, telecom operators gradually start to support Internet protocol version 6 (IPv6), including terminal, access and core network. Meanwhile, intelligent terminal manufactures also launch both software and hardware development supporting IPv6. Due to those factors mentioned above, mobile IPv6 application will become a trend inevitably. In the Internet protocol family, IPv4 is mainly designed aiming at wired network mode. With limited number of IP address available for network distribution and insufficient support for network node mobility, IPv4 cannot satisfy mobile internet’s development requirements. Based on original IP protocol, mobile IP protocol is proposed to support mobile nodes, which makes it realizable to access internet via various mobile devices under any circumstance. Mobile IP protocol is mainly designed to keep the continuity of communication between mobile nodes, without changing their IP address when connecting to other network access points. As a corporate body subordinate to IETF (Internet Engineering Task Force), mobile IP protocol group put forward IPv4 proposals in 1996[1], which have solved the reliability, security, scalability and media related problems of mobile Internet. Compared with mobile IPv4, mobile IPv6 combines with new features of IPv6 and makes further mobile nodes roaming in NGN more smoothly, thus the mobile network can be accessible at any time. Mobile IPv6 has more complete functions compared to IPv4, and it breaks several fundamental restrictions. It provides specific IP addresses for all mobile terminals and will eventually replace IPv4 using currently. Resolving the problem of IP address resource exhaustion as well as effective security supporting in network layer make it to be the dominant network protocol in NGN.
