Secure Aggregation with Top-K Sparsification in Decentralized Federated Learning

Hengxuan Tang, Jinbao Zhu, Xiaohu Tang

Secure aggregation is a vital component for mitigating gradient leakage in federated learning, but its communication cost conventionally scales with the gradient dimension. This be…

The Capacity of Information-Theoretic Secure Aggregation in Federated Learning

Lanxin Yi, Jinbao Zhu, Kai Wan +1

Secure aggregation allows a server to aggregate users' local updates while preserving update privacy. Existing information-theoretic problems typically assume that correlated rando…

A General Coding Framework for Adaptive Private Information Retrieval

Jinbao Zhu, Xiaohu Tang

The problem of -colluding private information retrieval (PIR) enables the user to retrieve one out of files from a distributed storage system with servers without reveal…

Improved Constructions for Secure Multi-Party Batch Matrix Multiplication

Jinbao Zhu, Qifa Yan, Xiaohu Tang

This paper investigates the problem of Secure Multi-party Batch Matrix Multiplication (SMBMM), where a user aims to compute the pairwise products $\mathbf{A}\divideontimes\mathbf{B…

Capacity-Achieving Private Information Retrieval Schemes from Uncoded Storage Constrained Servers with Low Sub-packetization

Jinbao Zhu, Qifa Yan, Xiaohu Tang +1

This paper investigates reducing sub-packetization of capacity-achieving schemes for uncoded Storage Constrained Private Information Retrieval (SC-PIR) systems. In the SC-PIR syste…
