We consider a multi-agent consensus problem in the presence of adversarial agents. The adversaries are able to listen to the inter-agent communications and try to estimate the state of the agents. The agents have a limited bit-rate for communication and are required to quantize the transmitted signal in order to meet the bit-rate constraint of the communication channel. We propose a consensus protocol that is protected against the adversaries, i.e., the expected mean-square error of the adversary state estimate is lower bounded. In order to deal with the bit-rate constraint, we propose a dynamic quantization scheme that guarantees protected consensus.

受到通讯和隐私限制的多智能体共识

在对抗性代理存在的情况下，我们考虑了多代理共识问题。对手能够侦听代理之间的通信并尝试估计代理的状态。代理具有有限的通信比特率，并且需要量化传输的信号，以满足通信信道的比特率约束。我们提出了一种防止对手攻击的共识协议，即，对手状态估计的预期均方误差是下界。为了处理比特率约束，我们提出了一种动态量化方案，该方案可以保证受保护的共识。
