摘　　要：基于区块链技术,提出具有身份认证和任务监管的声誉管理系统(Reputation Management System with Identity Authentication and Task Supervisor,RMS-IATS),解决群机器人内拜占庭机器人的识别问题,避免拜占庭机器人对群机器人造成安全威胁.首先,改进经典的基于区块链的群机器人声誉管理系统(Reputation Management System,RMS),引入惩罚因子,针对长期存在拜占庭行为的机器人实施更严厉的声誉值惩罚.其次,为了加快拜占庭机器人的识别速度,设计一种身份认证协议,将身份非法的机器人赋予一个较低的初始声誉值.再者,设计一种双层通信网络,用于机器人间的通信,解决群机器人系统因采用区块链技术带来的通信延迟问题.最后,通过仿真实验验证基于区块链的RMS-IATS和双层通信网络的有效性.相比经典的群机器人RMS,RMS-IATS在仿真模拟中识别不同类型拜占庭机器人所需的时间更短.相比使用区块链技术,在系统中使用双层通信网络进行通信时,可大幅减少系统的最大通信延迟.A reputation management system with identity authentication and task supervisor(RMS-IATS)for swarm robotics via blockchain technology is proposed to identify Byzantine robots within the swarm robotics and avoid the security threat caused by Byzantine robots to swarm robotics.Firstly,a classical blockchain-based swarm robotics reputation management system(RMS)is improved by introducing penalty factors,and a severer reputation value penalty is imposed on the robotics with long-term Byzantine behavior.Secondly,to speed up the identification of Byzantine robots within swarm robotics,an identity authentication protocol is devised,and thus lower initial reputation scores are assigned to the robots with unauthorized identities.Next,a dual-layer communication network for communication between robots is designed to solve the communication latency issue caused by blockchain in the swarm robotics system.Finally,the feasibility of the proposed blockchain-based RMS-IATS and dual-layer communication network is proved through simulations.The identification time for different types of Byzantine robots is shortened by RMS-IATS compared with the classical RMS for swarm robotics,and the maximum communication latency of the system is reduced by the proposed dual-layer communication network compared with the blockchain.
