摘要:

随着认知无线电网络(CRN)技术的不断发展,安全问题日益受到重视。模仿主用户(PUE)是一种典型的易于实现且对CRN影响巨大的攻击行为,根据产生的原因、目的和过程的差异,可以分为恶意不端次用户PUE和自私不端次用户PUE 2类攻击。已有文献大多针对前者进行了分析,而对后者分析极少。重点对两者进行了区分,提出了四维连续时间马尔科夫链分析模型,详细地分析了自私不端次用户PUE攻击对正常次用户通信性能的影响,并对比了几类典型的PUE攻击检测技术。通过仿真结果可以看出:PUE攻击检测技术引入自私不端次用户检测机制极为必要,可以有效地改进检测效果。

Abstract:

Cognitive radio network(CRN)is an effective technology and a hot research direction which could solve the problem of deficient resource and revolutionize utilization.And its safety technology attracted more and more researches.Primary user emulation(PUE)is a typically easily and largely affecting attack.PUE attacked come from both malicious misbehavior secondary users(MMU)and selfish misbehavior secondary users(SMU).The former was studied much more deeply than the later one.Distinguishing MMU and SMU,a four dimensional continuous time markov chain model to analyze the communication performance of normal secondary users under PUE attacks,and typically affected by SMUs was proposed.Furthermore,several PUE detection technologies were compared.The emulation results indicate that the SMU detection mechanism is essential for the PUE attack detection technology,which can improve the detection effects largely.

Key words: cognition radio networks (CRN), spectrum sensing, communication performance, secondary user, primary user emulation(PUE)
