Security Issues in Mobile Communication with MIPv6: A Survey

Achieving secured mobile communication is the most important job nowadays, while mobile communication becomes an essential part of human life. Special features like Route Optimization and enhanced address formats make the Mobile IPv6 very famous and a dominant part in the mobile communication area. There are so many advanced features available in Mobile IPv6. When the number of users increases, simultaneously new security threats also appear. Introduction of Route Optimization increases the performance of the communication by avoiding triangular routing which is available in former version of Mobile IP (i.e. MIPv4) at the same time it introduces new security threats also. Route Optimization follows a new route which may not be familiar for the nodes. The nodes may be at any area of the Internet and they may have not previous relationship among them. Securing this kind of route and the packet transfer is more critical. Many researchers found solutions for securing the Mobile IPv6 communications. But unfortunately, they have some drawbacks which cannot provide 100% security. In this paper, many security threats and solutions given by various researchers are analyzed.
