Research On IPv6 Address Scanning Technology Based On TGAs

To deal effectively with the problem of IPv4 address depletion,our country pays great attention to the development and application of IPv6.IPv6 network is being deployed on a large scale and some applications are gradually supporting it.At the same time of IPv6 application,network security and network management are considered elements.Address scanning technology is indispensable in realizing network security and network management.It is the basis of asset discovery,vulnerability scanning and penetration testing.Previous studies on address scanning technology focused on IPv4,no longer applicable to IPv6 network environments.The TAGs-based IPv6 address scanning technology is applicable in the research field of IPv6 address scanning.At present,in the research of IPv6 address scanning technology,some researchers have proposed various heuristic IPv6 address scanning algorithms one after another.These algorithms use the collected seed addresses as input and output the most likely active IPv6 address set as scanning target,which greatly reduces the scanning range of active address space.But these algorithms often scan only a part of the addresses and have the problem of low hit rate.To effectively improve the hit rate of the target addresses,this paper proposes a TGAs-based IPv6 address scanning technique to scan the complete address.First,it summarizes and analyzes the present situation IPv6 address assignment and address pattern usage.Second,using the existing IPv6 address scanning tools and public data set,we get millions of orders of magnitude IPv6 address sample data,and randomly generate seed addresses through the address sets after data preprocessing.Then the core of the target generation algorithm is expounded,that is,to construct IPv6 seed addresses entropy structure and clustering algorithm,to mine the IPv6 address characteristics,and to predict the most likely surviving target address set through the seed address,and then to realize the scanning of the IPv6 address.Experimental results show that the target generation algorithm compared with the existing algorithms,IPv6 address hit rate has improved.Finally,the TGAs-based IPv6 address scanning system is designed and implemented.
