Abstract: In the current mimetic authentication scenario based on channel state information (CSI), existing dynamic scheduling algorithms suffer from insufficient authentication performance due to inadequate consideration of the heterogeneity of execution entities. This paper proposes a CSI featuresbased heterogeneous executor dynamic scheduling algorithm (CFHEDA). The algorithm comprehensively quantifies the correlation between CSI features and the heterogeneity of execution entities to construct a featurebased heterogeneous execution entity matrix. Based on this, the algorithm integrates dynamic historical threat assessment with an iterative greedy strategy to prioritize maximizing feature coverage. It selects execution entities by integrating a comprehensive score that considers contributions from heterogeneity, historical risk, and failure indices. Through attack collision simulation experiments, this paper compares four algorithms, including the highorder heterogeneous scheduling algorithm (HFAWA). The experiments demonstrate that under different numbers of execution entities, CFHEDA consistently achieves the best performance, with average defense success rates and average attack interception rates improved compared to existing algorithms, and overall performance enhanced by approximately 5% to 12%.

摘要： 针对当前基于信道状态信息(channel state information, CSI)的拟态认证场景中，现有动态调度算法因对执行体异构性考量不充分而导致认证性能受限的问题，提出一种基于CSI的异构执行体动态调度算法(CSI featuresbased heterogeneous executor dynamic scheduling algorithm, CFHEDA).该算法通过综合量化CSI特征相关性与执行体自身异构性,构建基于特征的执行体异构性矩阵，并在此基础上，结合历史威胁动态评估以及迭代贪心策略，优先最大化特征覆盖，通过融合异构性贡献、历史风险评估与失陷指数的综合评分选择执行体.通过攻击碰撞仿真实验对比了高阶异构调度算法(HFAWA)等4种算法.实验表明，在不同执行体数量下CFHEDA表现均为最优，其平均防御成功率与平均攻击拦截率较现有算法均有提升，综合性能提升约5%~12%.
