Hierarchical Secure Distributed Linearly Separable Computation with Arbitrary Heterogeneous Data Assignment
Ziting Zhang, Chenyi Sun, Kai Wan +1
This paper studies secure distributed linearly separable computation over a three-layer hierarchical network, where clustered users communicate with a central server through relays…
Fundamental Limits of Hierarchical Secure Aggregation with Cyclic User Association
Xiang Zhang, Zhou Li, Kai Wan +3
Secure aggregation is motivated by federated learning (FL) where a cloud server aims to compute an {aggregated} model (i.e., weights of deep neural networks) of the locally-trained…
A New Construction Structure on Coded Caching with Linear Subpacketization: Non-Half-Sum Disjoint Packing
Minquan Cheng, Huimei Wei, Kai Wan +1
Coded caching is a promising technique to effectively reduce peak traffic by using local caches and the multicast gains generated by these local caches. We prefer to design a coded…
PDA Construction via Union of Cartesian Product Cache Configurations for Coded Caching
Jinyu Wang, Minquan Cheng, Kai Wan +1
Caching is an efficient technique to reduce peak traffic by storing popular content in local caches. Placement delivery array (PDA) proposed by Yan et al. is a combinatorial struct…
Optimal Communication and Key Rate Region for Hierarchical Secure Aggregation with User Collusion
Xiang Zhang, Kai Wan, Hua Sun +3
Secure aggregation is concerned with the task of securely uploading the inputs of multiple users to an aggregation server without letting the server know the inputs beyond their su…
Decentralized Uncoded Storage Elastic Computing with Heterogeneous Computation Speeds
Wenbo Huang, Xudong You, Kai Wan +2
Elasticity plays an important role in modern cloud computing systems. Elastic computing allows virtual machines (i.e., computing nodes) to be preempted when high-priority jobs aris…
