Detailed Description

A PIR client for the IT-PIR protocol by Goldberg (2007) over GF(2^E).

Supported fields are GF(2^8) and GF(2^16). This protocol was introduced in Improving the Robustness of Private Information Retrieval and revisited in

Parameters

params	Parameters for the client.

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.
