t-Private Information Retrieval Schemes Using Transitive Codes
Ragnar Freij-Hollanti, Oliver W. Gnilke, Camilla Hollanti +3
This paper presents private information retrieval (PIR) schemes for coded storage with colluding servers, which are not restricted to maximum distance separable (MDS) codes. PIR sc…
The Extension Theorem for Bi-invariant Weights over Frobenius Rings and Frobenius Bimodules
Oliver W. Gnilke, Marcus Greferath, Thomas Honold +2
We give a sufficient condition for a bi-invariant weight on a Frobenius bimodule to satisfy the extension property. This condition applies to bi-invariant weights on a finite Frobe…
Improved User-Private Information Retrieval via Finite Geometry
Oliver Gnilke, Marcus Greferath, Camilla Hollanti +3
In a User-Private Information Retrieval (UPIR) scheme, a set of users collaborate to retrieve files from a database without revealing to observers which participant in the scheme r…
Private Information Retrieval Schemes for Coded Data with Arbitrary Collusion Patterns
Razane Tajeddine, Oliver W. Gnilke, David Karpuk +3
In Private Information Retrieval (PIR), one wants to download a file from a database without revealing to the database which file is being downloaded. Much attention has been paid…
