摘　　要：由于在数据共享和信任上的特点,区块链及其联盟链可能被集成到新一代的无线接入系统。针对大规模物联网应用场景所需要的安全接入机制,提出一种分布式的安全资源分配方案。该方案是一种凸优化证明共识机制,并且便于解决优先级问题。仿真结果表明,所提算法能够在大设备数目下提高无线接入网的安全性能和实现差异化的无线资源共享。Due to the characteristics of data sharing and trust,the blockchain and its alliance chain may be integrated into a new generation of wireless access systems.Aiming at the security access mechanism required by large⁃scale Internet of Things(IoT)application scenarios,a distributed security resource allocation scheme is proposed.The algorithm is a consensus mechanism of convex optimization proof and is easy to solve the priority problem.Simulation results show that the algorithm can improve the security performance of wireless access networks and realize differentiated wireless resource sharing on a large number of devices.
