New Constructions of Optimal -LRCs via Algebraic Function Fields
Yuan Gao, Haoming Shi, Weijun Fang
The paper presents new constructions of optimal locally repairable codes with parameters (r,δ) by leveraging automorphism groups of elliptic, hyperelliptic, and superelliptic funct…
New -Secure -Private Information Retrieval Schemes via Rational Curves and Hermitian Curves
Yuan Gao, Weijun Fang, Jingke Xu +1
-secure and -private information retrieval (XSTPIR) is a variant of private information retrieval where data security is guaranteed against collusion among up to servers…
Making Wide Stripes Practical: Cascaded Parity LRCs for Efficient Repair and High Reliability
Fan Yu, Guodong Li, Si Wu +2
Erasure coding with wide stripes is increasingly adopted to reduce storage overhead in large-scale storage systems. However, existing Locally Repairable Codes (LRCs) exhibit struct…
Bounds and Optimal Constructions of Generalized Merge-Convertible Codes for Code Conversion into LRCs
Haoming Shi, Weijun Fang, Yuan Gao
Error-correcting codes are essential for ensuring fault tolerance in modern distributed data storage systems. However, in practice, factors such as the failure rates of storage dev…
Efficiently Achieving Secure Model Training and Secure Aggregation to Ensure Bidirectional Privacy-Preservation in Federated Learning
Xue Yang, Depan Peng, Yan Feng +3
Bidirectional privacy-preservation federated learning is crucial as both local gradients and the global model may leak privacy. However, only a few works attempt to achieve it, and…
