一种 HSS移动目标防御方法
Moving target defense approach of HSS
摘要
Abstract
In current mobile core network,HSS is facing deny of service attack,man in middle attack and other security threats.Besides,in traditional static networks,attackers have asymmetric advantages over defenders.To address the prob-lems,this paper presented a moving target defense approach of HSS based on the study of dynamic address in moving target de-fense.It also modeled and analysed the attacker-filter problem and proposed a fast greedy algorithm and a convex optimization method to efficiently perform the address switch strategy.The simulation results show that the fast greedy algorithm prevents at-tackers while significantly reducing the time complexity;the convex optimization method reduces the times of address switch byincreasing solution space and lowers the impact on normal communication of core network.关键词
