On Secure Gradient Coding with Uncoded Groupwise Keys
Xudong You, Kai Wan, Xiang Zhang +3
This paper considers a new secure gradient coding problem with uncoded groupwise keys, formalized as a (K, N, N_r, M, S) secure gradient coding model, where a user aims to compute…
Taming Subpacketization without Sacrificing Communication: A Packet Type-based Framework for D2D Coded Caching
Xiang Zhang, Giuseppe Caire, Mingyue Ji
Finite-length design is essential for making coded caching practical, as the optimal communication gains of existing schemes often require prohibitively large subpacketization. Thi…
Information-Theoretic Secure Aggregation over Regular Graphs
Xiang Zhang, Zhou Li, Han Yu +4
Large-scale decentralized learning frameworks such as federated learning (FL), require both communication efficiency and strong data security, motivating the study of secure aggreg…
On Resilient and Efficient Linear Secure Aggregation in Hierarchical Federated Learning
Shudi Weng, Xiang Zhang, Yizhou Zhao +3
In this paper, we study the fundamental limits of hierarchical secure aggregation under unreliable communication. We consider a hierarchical network where each client connects to m…
Multiaccess Coded Caching with Heterogeneous Retrieval Costs
Wenbo Huang, Minquan Cheng, Kai Wan +3
The multiaccess coded caching (MACC) system, as formulated by Hachem {\it et al.}, consists of a central server with a library of files, connected to cache-less users via a…
A New Construction Structure on Coded Caching with Linear Subpacketization: Non-Half-Sum Latin Rectangle
Yongcheng Yang, Minquan Cheng, Kai Wan +1
Coded caching is recognized as an effective method for alleviating network congestion during peak periods by leveraging local caching and coded multicasting gains. The key challeng…
Placement Delivery Array for Cache-Aided MIMO Systems
Yifei Huang, Kai Wan, Minquan Cheng +2
We consider a cache-aided multiple-input multiple-output (MIMO) network, where a server equipped with antennas and a library of equal-size files communicates…
A New Construction Structure on MISO Coded Caching with Linear Subpacketization: Half-Sum Disjoint Packing
Bowen Zheng, Minquan Cheng, Kai Wan +1
In the cache-aided multiple-input single-output (MISO) broadcast channel (BC) system, the server is equipped with antennas and communicates with single-antenna…
Distributed Linearly Separable Computation with Arbitrary Heterogeneous Data Assignment
Ziting Zhang, Kai Wan, Minquan Cheng +2
Distributed linearly separable computation is a fundamental problem in large-scale distributed systems, requiring the computation of linearly separable functions over different dat…
Optimal Rate Region for Multi-server Secure Aggregation with User Collusion
Zhou Li, Xiang Zhang, Kai Wan +3
Secure aggregation is a fundamental primitive in privacy-preserving distributed learning systems, where an aggregator aims to compute the sum of users' inputs without revealing ind…
A New Construction Structure on Multi-access Coded Caching with Linear Subpacketization: Cyclic Multi-Access Non-Half-Sum Disjoint Packing
Mengyuan Li, Minquan Cheng, Kai Wan +1
We consider the multi-access coded caching system introduced by Hachem et al., which consists of a central server with files and cache nodes, each of memory siz…
A Low-Complexity Framework for Multi-access Coded Caching Systems with Arbitrary User-cache Access Topology
Ting Yang, Kai Wan, Minquan Cheng +3
This paper studies the multi-access coded caching (MACC) problem with arbitrary user-cache access topology, which extends existing MACC models that rely on highly structured and co…
