Comparative studies of IPv6 tunnel security
Kejun Gu, Liancheng Zhang, Zhenxing Wang, Yazhou Kong · 2017
Along with the deployment of IPv6 is becoming more and more widely, IPv4 networks will coexist with IPv6 networks for a relatively long time. The tunnel mechanisms are the best choice for a smooth transition to IPv6. With the wild deployment of the tunnel mechanisms, more and more security issues have been noticed. The security problems faced by tunnel mechanisms such as injection, address spoofing and reflector attack are analyzed, and corresponding countermeasures are concluded into three directions: filter, deep packet inspection (DPI) and IPsec. Some questions are pointed out for research in next steps.
