Building an IPv6 address generation and traceback system with NIDTGA in Address Driven Network在地址驱动网络中构建嵌入可扩展用户网络身份标识和时间信息的 IPv6 地址生成和追溯系统

In the design and construction process of Next Generation Internet, it is important to identify the source of each IP packet forwarding accurately, especially for the support of precise fine-grained management, control, traceability and improving the trustworthiness of the Internet. This paper designed a scalable Network Identity (NID) scheme for the Internet users, proposed NIDTGA (Network Identity and Time Generated Address), an IPv6 address generation algorithm embedded NID and time information, then designed and implemented an IPv6 address generation and traceback system based on NIDTGA. The design of NIDTGA, which reflects the length, time and owner attributes of the IP address, can be a good support to ADN (Address Driven Network). At the same time, by embedding the key elements of user identity and time in the IPv6 address, and by taking into account both the traceability and privacy, NIDTGA can provide a technical basis for the establishment of the network trust mechanism, and achieve the traceability of security event.
