Explicit Construction of Minimum Storage Rack-Aware Regenerating Codes for All Parameters
Liyang Zhou, Zhifang Zhang
We consider the rack-aware storage system where nodes are organized in racks each containing nodes, and any nodes can retr…
Rack-Aware Regenerating Codes with Fewer Helper Racks
Zhifang Zhang, Liyang Zhou
We consider the rack-aware storage system where \(n\) nodes are organized in \(\bar{n}\) racks each containing \(u\) nodes, and any \(k\) nodes can retrieve the stored file. Moreov…
A Capacity-Achieving -PIR Scheme Based On MDS Array Codes
Jingke Xu, Yaqian Zhang, Zhifang Zhang
Suppose a database containing records is replicated in each of servers, and a user wants to privately retrieve one record by accessing the servers such that identity of the…
An Improved Cooperative Repair Scheme for Reed-Solomon Codes
Yaqian Zhang, Zhifang Zhang
Dau et al. recently extend Guruswami and Wootters' scheme (STOC'2016) to cooperatively repair two or three erasures in Reed-Solomon (RS) codes. However, their scheme restricts to e…
Scalar MSCR Codes via the Product Matrix Construction
Yaqian Zhang, Zhifang Zhang
An cooperative regenerating code provides the optimal-bandwidth repair for any node failures in a cooperative way. In particular, an MSCR (minimum storage c…
Capacity-Achieving PIR Schemes with Optimal Sub-Packetization
Zhifang Zhang, Jingke Xu
Suppose a database containing records is replicated across servers, and a user wants to privately retrieve one record by accessing the servers such that identity of the ret…
