Information-Theoretic Decentralized Secure Aggregation with User Dropouts
Zhou Li, Xiang Zhang, Yizhou Zhao +2
This paper investigates the fundamental limits of information-theoretic decentralized secure aggregation (DSA) with user dropouts. We consider a fully decentralized network where $…
Optimal Communication Rate of Secure Aggregation over Ring Networks with Pairwise Keys
Xiang Zhang, Han Yu, Zhou Li +2
Information-theoretic topological secure aggregation (TSA)\cite{zhang2026information_regular} enables distributed users to compute neighborhood sums over arbitrary networks without…
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…
Compressed Sensing Inspired User Acquisition for Downlink Integrated Sensing and Communication Transmissions
Yi Song, Fernando Pedraza, Shuangyang Li +3
This paper investigates radar-assisted user acquisition for downlink multi-user multiple-input multiple-output (MIMO) transmission using Orthogonal Frequency Division Multiplexing…
