On Secure Gradient Coding with Uncoded Groupwise Keys
Xudong You, Kai Wan, Xiang Zhang +3
This paper considers a new secure gradient coding problem with uncoded groupwise keys, formalized as a (K, N, N_r, M, S) secure gradient coding model, where a user aims to compute…
Multiaccess Coded Caching with Heterogeneous Retrieval Costs
Wenbo Huang, Minquan Cheng, Kai Wan +3
The multiaccess coded caching (MACC) system, as formulated by Hachem {\it et al.}, consists of a central server with a library of files, connected to cache-less users via a…
On the Optimal Source Key Size of Secure Gradient Coding
Yang Zhou, Wenbo Huang, Kai Wan +1
With gradient coding, a user node can efficiently aggregate gradients from server nodes processing local datasets, achieving low communication costs and maintaining resilience agai…
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…
