Order-Optimal Coded Caching With File and Demand Privacy

Han Fang, Nan Liu, Wei Kang

We study coded caching with joint file and demand privacy: each user recovers its requested file while learning nothing about the remaining files and the other users' requests join…

Secure Multi-Access Coded Caching: A Lifting Approach

Han Fang, Qinyi Lu, Nan Liu +1

We construct secure cyclic multi-access coded caching schemes by re-encoding the caches of a secure single-access scheme and reusing its multicast message unchanged. For a library…

Secure D2D Coded Caching under Radius-Limited Connectivity via Lifting

Han Fang, Nan Liu, Wei Kang

Secure device-to-device (D2D) caching requires users to generate delivery signals from their own caches and to recover their requested files without learning the other files. We co…

Polar Code Based Federated Learning: Convergence Analysis and Resource Allocation

Han Xiao, Wei Kang, Nan Liu

Federated learning (FL) enables collaborative model training across distributed devices without sharing raw data; however, it faces significant communication bottlenecks and channe…

Improved Characterization of the Memory-Rate Tradeoff for Demand-Private Coded Caching With Multiple Demands

Qinyi Lu, Nan Liu, Wei Kang +1

We consider a coded caching problem with multiple demands under a privacy constraint. In this problem, a server with access to files serves users over a shared link, and ea…

Movable Antenna Assisted Dual-Polarized Multi-Cell Cooperative AirComp: An Alternating Optimization Approach

Mingyu Hu, Nan Liu, Wei Kang

Over-the-air computation (AirComp) is a key enabler for distributed optimization, since it leverages analog waveform superposition to perform aggregation and thereby mitigates the…
