Create a HEMaster process for use in a distributed homomorphic encrypted (HE) computation

HEMaster objects run a distributed computation based upon a definition file that encapsulates all information necessary to perform a computation. A master makes use of two non-cooperating parties which communicate with sites that perform the actual computations using local data.

Usage

HEMaster$run(debug = FALSE)

Arguments

debug

a flag for debugging, default FALSE

The objects of this class are cloneable with this method.

Usage

HEMaster$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
