Detailed Description

A PIR server for the IT-PIR protocol by Goldberg (2007) over the integers modulo p.

This protocol was introduced in Improving the Robustness of Private Information Retrieval and revisited in

• Revisiting the Computational Practicality of Private Information Retrieval
• Practical PIR for Electronic Commerce
• Optimally Robust Private Information Retrieval
• One (Block) Size Fits All: PIR and SPIR Over Arbitrary-Length Records via Multi-block PIR Queries
• Outsourced Private Information Retrieval with Pricing and Access Control
