This letter proposes a low-latency secure mobile edge computing (MEC) system where multiple users offload computing tasks to a base station in the presence of an eavesdropper. We jointly optimize the users’ transmit power, computing capacity allocation, and user association to minimize the computing and transmission latencies over all users subject to security and computing resource constraints. Numerical results show that our proposed algorithm outperforms baseline strategies. Furthermore, we highlight a novel trade-off between the latency and security of MEC systems.

低延迟安全移动边缘计算系统的卸载优化

这封信提出了一种低延迟安全移动边缘计算 (MEC) 系统，其中多个用户在存在窃听者的情况下将计算任务卸载到基站。我们共同优化用户的传输功率、计算能力分配和用户关联，以最小化所有受安全和计算资源约束的用户的计算和传输延迟。数值结果表明，我们提出的算法优于基线策略。此外，我们强调了 MEC 系统的延迟和安全性之间的新权衡。
