摘要

研究了存在双窃听威胁的单站通信感知一体化（integrated sensing and communication，ISAC）系统。该系统中，基站与合法用户通信的同时，接收其反射的回波信号进行感知，而环境中存在窃听通信信息的通信窃听者（communication eavesdropper，ComEve）和监听合法用户回波信号进行被动感知窃听的感知窃听者（sensing eavesdropper，SenEve）。针对感知窃听问题，推导了感知保密速率的表达式，并建立了通信和感知保密速率的加权优化模型，求得兼顾两者安全性能的系统性能上界。为解决实际ISAC系统中的安全性能优化问题，建立了不同约束条件下最大化感知或通信保密速率的优化问题，得到了不同需求下的最优安全预编码设计方案。仿真结果表明，所提预编码方案相较于单一考虑通信或感知安全的预编码方案，系统整体安全性能平均提升约30%。

Abstract

A single-station integrated sensing and communication (ISAC) system subject to dual eavesdropping threats was investigated. In this system

the base station communicates with a legitimate user and simultaneously receives the reflected echo signal from it for sensing. However

there is a communication eavesdropper (ComEve) that wiretaps communication information

and a sensing eavesdropper (SenEve) that passively eavesdrops on the legitimate user’s echo signal for sensing. Focusing on the sensing eavesdropping issue

the expression of sensing secrecy rate was derived

and a weighted optimization model of communication and sensing secrecy rates was formulated. This model helped to find the upper bound of system performance that balanced the security of both aspects. To enhance the security of practical ISAC systems

the optimization problems were established to maximize sensing or communication secrecy rate under different constraints

yielding optimal secure precoding designs for different requirements. Simulation results indicate that the proposed precoding scheme improves the overall system security performance by approximately 30% on average compared with the schemes that only consider the security of communication or sensing.
