Private Information Retrieval Schemes with Regenerating Codes

Julien Lavauzelle, Razane Tajeddine, Ragnar Freij-Hollanti +1

A private information retrieval (PIR) scheme allows a user to retrieve a file from a database without revealing any information on the file being requested. As of now, PIR schemes…

Private Information Retrieval over Random Linear Networks

Razane Tajeddine, Antonia Wachter-Zeh, Camilla Hollanti

In this paper, the problem of providing privacy to users requesting data over a network from a distributed storage system (DSS) is considered. The DSS, which is considered as the m…

Private Information Retrieval from Coded Storage Systems with Colluding, Byzantine, and Unresponsive Servers

Razane Tajeddine, Oliver W. Gnilke, David Karpuk +2

The problem of Private Information Retrieval (PIR) from coded storage systems with colluding, byzantine, and unresponsive servers is considered. An explicit scheme using an

Robust Private Information Retrieval from Coded Systems with Byzantine and Colluding Servers

Razane Tajeddine, Oliver W. Gnilke, David Karpuk +2

A private information retrieval (PIR) scheme on coded storage systems with colluding, byzantine, and non-responsive servers is presented. Furthermore, the scheme can also be used f…

Robust Private Information Retrieval on Coded Data

Razane Tajeddine, Salim El Rouayheb

We consider the problem of designing PIR scheme on coded data when certain nodes are unresponsive. We provide the construction of -robust PIR schemes that can tolerate up to
