  本文针对无人机组网过程中的密钥管理与认证问题,面向不同应用场景提出了有控制站支持的无人机网络认证方案(ASUSG)和无控制站支持的无人机网络认证方案(ASWGS),实现了无人机节点间的密钥管理和身份认证。其中,ASUSG 充分利用控制站计算资源充足、通信链路稳定的特点,将控制站作为密钥生成中心,控制站基于椭圆曲线密码体制对节点进行认证和分发密钥,节点间的认证借助控制站完成;ASWGS 基于身份密码体制设计,通过门限机制使网络内节点相互协作分布式地生成节点密钥对,密钥对生成的过程中采用双线性对运算实现节点间的双向认证,可以识别出恶意节点,利用生成的密钥对完成了节点间的身份认证与密钥协商。详细的安全分析和论证表明本文所提方案可抵抗典型的安全攻击;性能仿真测试表明与已有方案相比,本文所提方案在保证安全性的前提下能有效降低全局计算开销。

CPS 系统架构逐渐成为工业互联网建构的重要途径,对于未来智联网建设也具有重要研究价值。由于区块链环境下,CPS系统呈现高度分布式、异构耦合等特点,如何对异构耦合的CPS 面临的级联失效等过程进行可靠性分析变得至关重要。迄今为止,该问题尚无有效而彻底的解决方案。本文首先对耦合异构CPS 系统进行了建模,并给出该系统模式下级联失效过程的理论分析;在此基础上,基于仿真实验对比分析,给出影响异构耦合CP
