Plug-in policy for DoS attack defense mechanism based on end hopping
Lu Kai · Journal of Communications · 2009
Denial of service(DoS) attacks have been a serious threat on the computer network security, and have caused huge loss.Shi et al.proposed a new network security model based on end hopping, which can effectively defend DoS at-tacks.By analyzing the end hopping mechanism, a serious problem in it was found, namely, the network leakage of end information, which is likely to invalidate the function of this mechanism.Therefore, a set of plug-in policies are added to the original model, which authenticate the clients and conceal the actual end information of servers.Experimental results show that the plug-in mechanism is able to avoid the network leakage of end information and imposes little influence on the capacity of servers.
