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…

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…
