摘要
认知无线网络中的合谋攻击将严重危害频谱的安全感知和资源的可靠分配.文章首先对恶意次用户的合谋行为做出分析,然后将Vickrey-Clarke-Groves(VCG)机制与信誉机制有效融合,提出了新的分布式安全频谱感知策略VCG-RSS.VCGRSS利用VCG机制激励次用户提供真实的推荐信誉值,然后通过信誉机制来计算协作用户的可信度,最终实现安全的协作感知.仿真结果表明VCG-RSS能够有效地抵御合谋攻击和实现安全协作,提高频谱感知的准确性.
Collusion attacks will cause serious damages to the security of the spectrum sensing and the reliability allocation of resources in cognitive radio network. Based on analyzing the malicious collusion behavior of users and integrating Vickrey-Clarke-Groves （ VCG ） mechanism with reputation mechanism effectively, this paper proposes a new distributed security spectrum sensing strategy-- VCG-RSS. VCG-RSS can achieve secure collaborative sensing by utilizing VCG to encourage the second user to provide a real recommended trust-based value and calculating the reliability of collaborative users though the reputation mechanism. The simulating results indicate that VCG-RSS can effectively resist collusion attacks,implement security cooperation, and improve the accuracy of spectrum sensing.
