【摘要】 IMS是下一代网络的核心技术,虽然IMS为未来的多媒体数据业务提供了一个通用平台,但IMS网络容易受到来自外部的一些攻击。该文针对IMS网络中的RECISTER攻击,提出一种自适应累积和算法。该算法通过流量模型把网络中的正常流量与攻击流量区分开,并且在进行攻击检测时,自适应地调整检测阈值,从而可以检测出强度较小的攻击。仿真结果表明,应用自适应累积和算法的检测系统具有较高的检测率和较低的误警率。更多还原

【Abstract】 IMS is the core technology of next generation network(NGN),although IMS provide a common platform for die multimedia data business of future,IMS network will suffer from some attacks.This paper aims at the REGISTER attacks and proposes an algorithm which is called the adaptive CS algorithm.This algorithm can differentiate normal traffic from attack traffic by using the model of traffic,when the system is detecting attacks,it can modify detection threshold adaptively,so it can detect the attack which has low intensity. The result of simulation shows that detection system which applies adaptive CS algorithm has upper detection rate and lower false alarms rate.更多还原
