Towards Practical Private Information Retrieval from MDS Array Codes
Jie Li, David Karpuk, Camilla Hollanti
Private information retrieval (PIR) is the problem of privately retrieving one out of original files from severs, i.e., each individual server learns nothing about the file…
Towards the Capacity of Private Information Retrieval from Coded and Colluding Servers
Lukas Holzbaur, Ragnar Freij-Hollanti, Jie Li +1
In this work, two practical concepts related to private information retrieval (PIR) are introduced and coined full support-rank PIR and strongly linear PIR. Being of full support-r…
A Systematic Construction of MDS Codes With Small Sub-packetization Level and Near-Optimal Repair Bandwidth
Jie Li, Yi Liu, Xiaohu Tang
In the literature, all the known high-rate MDS codes with the optimal repair bandwidth possess a significantly large sub-packetization level, which may prevent the codes to be impl…
A Generic Transformation for Optimal Node Repair in MDS Array Codes over
Jie Li, Xiaohu Tang, Camilla Hollanti
For high-rate linear systematic maximum distance separable (MDS) codes, most early constructions could initially optimally repair all the systematic nodes but not all the parity no…
