Detailed Description

A PIR client 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

Constructor & Destructor Documentation

PercyClient_ZZ_p	(	const PercyClientParams *	params,
		nservers_t	num_servers,
		nservers_t	t,
		sid_t *	sids,
		PercyStats *	stats = NULL
	)

Constructor.

Parameters

params	Parameters for the client.
num_servers	The number of servers used
t	The privacy level. I.e. the maximum number of servers that can collude and the queries will remain private.
sids	An array of IDs for the servers that will be used.
stats	Statistics collection object. No statistics will be collected if NULL.
