摘　　要：研究了认知无线网络的安全方案。针对认知无线网络存在的安全问题,结合网络的特点,提出了一种基于身份的安全解决方案,即Yu-IBE方案。该方案无需在线可信第三方即可实现认知节点的身份认证,其功能与PKI类似,但认证链却简单很多。该安全解决方案能通过较少的基础设施实现系统密钥的分发、密钥定期更换、域内及跨域通信等功能。将Yu-IBE总体安全解决方案与已有的两种知名数据融合方案进行了对比仿真,结果显示,Yu-IBE方案在所列攻击类型下均具有较好的稳定性,认知正确率始终保持较高水平。Aiming at cognitive wireless network security issues and combining with the eharactensUcs oI me networK, an identity-based security solution named Yu-the IBE scheme was proposed. The solution can realize cognitive node au- thentication without online trusted third party. Its function is similar with PKI, but certification chain is much simpler than the PKI. This security solution can realize the function of system key distribution, key regularly replace, domain and cross-domain communication with less infrastructure. In addition, this paper compared overall security solution of YtrlBE with the existing two well-known data integration program. The simulation results show that the Yu-IBE pro- gram has better stability, and cognitive correct rate has remained relatively high level.
