基于区块链的无人机网络跨域身份认证研究

传统的无人机跨域身份认证的方案大多依赖公钥基础设施 （public key infrastructure，PKI）。该模型高度依赖可信第三方，易造成单点故障且认证效率低下。据此，提出基于区块链的无人机网络跨域身份认证协议方案，该方案不但可以有效实现无人机的跨域认证，且可以改善传统基于PKI模型面临的诸多安全问题。同时，为了实现无人机网络跨域认证的隐私保护，提出了可实现无人机跨域身份认证身份标识的匿名化的方法。安全性分析与仿真实验的结果表明，该方案不但可抵御常见网络攻击，在认证效率和时间开销上有明显提升。

Research on cross-domain identity authentication of unmanned aerial vehicle network based on blockchain

Most traditional drone cross-domain authentication schemes rely on PKI. This model relies heavily on trusted third parties, prone to single points of failure and low authentication efficiency. Accordingly, this paper proposed a blockchain-based UAV network cross-domain identity authentication protocol scheme, which not only effectively realized the cross-domain authentication of UAVs, but also improved many security problems faced by the traditional PKI-based model. At the same time, to discover the privacy protection of UAV network cross-domain authentication, this paper proposed a method to anonymize the UAV cross-domain identity authentication identity. The results of security analysis and simulation experiments show that the scheme can not only resist common network attacks, but also significantly improve authentication efficiency and reduce time overhead.
