摘要

考虑物理层安全辅助的私密文件传输问题，提出了带有边缘计算服务器的智能基站作为中继协助完成文件压缩、传输与解压的安全传输方案。首先使用空间泊松点过程刻画多个潜在窃听者场景下的安全传输概率，然后构建两跳总安全传输概率约束下的时延及能耗最小化问题。通过一维搜索结合线性规划，得到了最优压缩与解压方案。仿真结果表明，给定安全概率约束下私密信息速率小的链路在传输前需要进行文件压缩，反之不需要压缩，可直接传输。

Abstract

Considering a physical-layer-security-aided confidential document transmission problem

a secure transmission strategy was proposed where the base station equipped with a mobile edge computing (MEC) server served as a relay to help compress

forward

and decompress.First

the Poisson point process was used to calculate the secure transmission probability for the scenario with multiple potential eavesdroppers.Then

a delay and energy minimization problem was formulated under a constraint on the two-hop secure transmission probability.The optimal compression and decompression scheme was obtained using the one-dimensional search combined with linear programming.Simulation results show that the document compression is necessary for the link with small achievable secrecy rate under a given secure transmission probability; otherwise

the document should be directly transmitted without compression.
