摘要

摘要: 多智能体网络(Multi-agent network, MAN)协同执行任务时需要个体之间频繁交换并共享信息, 这对网络安全带来了巨大风险. 考虑网络中节点状态隐私保护问题, 提出一种基于隐写术的分布式一致性控制策略. 首先, 建立网络窃听者攻击模型, 提出面向隐私保护的分布式平均一致性控制算法. 理论分析表明, 所提算法不仅有效保护节点初始状态的隐私, 而且可以通过隐写载体信息主动诱导窃听者推测得出错误结论. 其次, 通过引入概率指标, 提出一种用于量化MAN隐私泄露指标的模型, 实现了对网络隐私泄露程度的准确描述. 并基于该模型, 从窃听者视角, 通过权衡对网络隐私泄露的影响与付出代价成本建立一个优化问题, 据此寻找最优效益攻击策略. 最后, 通过数值仿真分析, 对比现有算法验证了所提方法的有效性和优越性.

Abstract: Multi-agent network (MAN) requires frequent exchange and sharing of information among individuals in collaborative task execution, which poses significant risks to network security. To address the issue of privacy protection of node states in the network, a distributed consensus control strategy based on steganography is proposed. Firstly, an eavesdropper attack model is established, and a distributed privacy-preserving average consensus control algorithm is proposed. Theoretical analysis shows that the proposed algorithm not only effectively protects the privacy of node initial states but also can actively lead eavesdroppers to draw incorrect conclusions through steganographic carrier information. Secondly, a probabilistic indicator is introduced to quantify the privacy leakage index model for MAN, achieving an accurate description of the degree of network privacy leakage. Based on this model, an optimization problem is established from the eavesdropper＇s perspective by balancing the impact on network privacy leakage and the cost of attack, in order to find the optimal benefit attack strategy. Finally, through numerical simulation, the effectiveness and superiority of the proposed method are verified by comparing with existing algorithms.
