一种认知无线电Ad Hoc网络零知识共享信道协议

Shared Channel Protocol for Cognitive Radio Networks Based on Zero Knowledge

针对认知无线电Ad Hoc网络共享信道协商过程为自私行为提供过多频谱信息的情况,提出一种满足半诚实环境安全需求的零知识共享信道协议(Zero Knowledge Shared Channel Protocol,ZKSCP),该协议使用承诺协议将频谱信息和节点身份绑定,结合同态密钥和门限机制提供安全频谱计算,阻止自私节点对非共享信道信息的窥探,保证频谱计算的正确性,此外,灵活的门限协商机制使得该协议具有可扩展性和鲁棒性,可满足半诚实环境中共享信道协商的安全需求。

Currently some shared channel protocols let out much spectrum information, which gives change to self-behavior. To solve such question, a novel protocol （Zero Knowledge Shared Channel Protocol, ZK- SCP） was proposed in semi-honest model. Proposed protocol is applied to bang spectrum information and node identity, at time homomorphic key and threshold key are just combined to support secure spectrum computation,so the protocol can protect spectrum information from selfish node spying and ensure the spectrum computation is right. Moreover, this protocol has characteristic of extendibility and robustness with using flexible threshold consulting mechanism, and meets the security requirements of semi-honest model of cognitive radio networks.
