Multi-User Blind Symmetric Private Information Retrieval from Coded Servers
Jinbao Zhu, Qifa Yan, Xiaohu Tang
The problem of Multi-user Blind -secure -colluding Symmetric Private Information Retrieval from Maximum Distance Separable (MDS) coded storage system with Byzantine and $…
Coded Alternating Least Squares for Straggler Mitigation in Distributed Recommendations
Siyuan Wang, Qifa Yan, Jingjing Zhang +2
Matrix factorization is an important representation learning algorithm, e.g., recommender systems, where a large matrix can be factorized into the product of two low dimensional ma…
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…
Robust and Secure Cache-aided Private Linear Function Retrieval from Coded Servers
Qifa Yan, Daniela Tuninetti
This work investigates a system where each user aims to retrieve a scalar linear function of the files of a library, which are Maximum Distance Separable coded and stored at multip…
