Linear network codes for vector-linear network function computation over three-layer networks
Min Xu, Gennian Ge
We study vector-linear function computation over three-layer networks with a fixed target function and a fixed source-access pattern. We develop a support-constrained row-space fra…

Network function computation with vector linear target function and security function
Min Xu, Qian Chen, Gennian Ge
In this paper, we study the problem of securely computing a function over a network, where both the target function and the security function are vector linear. The network is mode…

On hierarchical secure aggregation against relay and user collusion
Min Xu, Xuejiao Han, Kai Wan +1
Secure aggregation (SA) is fundamental to privacy preservation in federated learning (FL), enabling model aggregation while preventing disclosure of individual user updates. This p…
