Comprehensive Survey of IPv6 Transition Technologies: A Subjective Classification for Security Analysis

抄録

Due to the depletion of the public IPv4 address pool, the transition to IPv6 became inevitable. However, this ongoing transition is taking a long time, and the two incompatible versions of the Internet Protocol must coexist. Different IPv6 transition technologies were developed, which can be used to enable communication in various scenarios, but they also involve additional security issues. In this paper, first, we introduce our methodology for analyzing the security of IPv6 transition technologies in a nutshell. Then, we develop a priority classification method for the ranking of different IPv6 transition technologies and their most important implementations, so that the vulnerabilities of the most crucial ones may be examined first. Next, we conduct a comprehensive survey of the existing IPv6 transition technologies by describing their application scenarios and the basics of their operation and we also determine the priorities of their security analysis according to our ranking system. Finally, we show that those IPv6 transition technologies that we gave high priorities, cover the most relevant scenarios.
