<p>Comparing the computation overhead of the proposed scheme with the approaches in refs. [25,51,89] (n: the number of shadow ids = 100, n: the number of aps = 10, and s: seg-size = 10).</p>将本研究所提方案的计算开销与参考文献[25,51,89]中的方法进行对比（参数说明：n为影子标识（shadow ids）数量=100，n为接入点（Access Points）数量=10，s为分段大小（seg-size）=10）。
