Note that compiling requires a FRESCO jar containing CRT support. This can be compiled from this repo. Code is compiled and packed using Maven:

mvn package

Tests CRT. In general the parameters are as follows

• domainInBits: the amount of bits to be available for computation.
• statSec: the statistical security parameter.
• batchSize: the size of the batch/underlying coputation.
• CRT/SPDZ: a string indicating whether to execute SPDZ or CRT.
• Covert/SemiHonest: a string indicating whether to execute covert or semi-honest preprocessing.
• myId: ID of the calling party. Must be in 1... parties.
• otherIP1: the IP of the first other party.
• otherIP2: the optional IP of the second other party.
• otherIPn: the optional IP of the nth other party.

Executable jars are as follows and found in the target folder after compilation:

fft-online

Tests FFT

java -jar fft-online.jar [domainInBits] [statSec] [batchSize] [CRT/SPDZ] [myId] [otherIP1] ([otherIP2] ...)

For example, run the following in two different terminals:

java -jar target/fft-online.jar 136 40 1024 CRT 1 localhost

and

java -jar target/fft-online.jar 136 40 1024 CRT 2 localhost

fixed-mult

Test fixpoint multiplication

java -jar fixed-mult.jar [domainInBits] [statSec] [batchSize] [CRT/SPDZ] [myId] [otherIP1] ([otherIP2] ...)

mult

Test normal, integer, multiplication

java -jar mult.jar [domainInBits] [statSec] [batchSize] [CRT/SPDZ] [myId] [otherIP1] ([otherIP2] ...)

noise-generation

Tests generation of needed correlated noise

java -jar noise-generation.jar [domainInBits] [statSec] [deterrence] [batchSize] [Covert/SemiHonest] [myId] [otherIP1] ([otherIP2] ...)

mascot

Tests offline preprocessing of triples

java -jar mascot.jar [domainInBits] [statSec] [batchSize] [SPDZ/CRT] [myId] [otherIP1] ([otherIP2] ...)

BitGen

Tests offline generation of bits needed for SPDZ truncation

java -jar SPDZBitGen [domainInBits] [statSec] [batchSize] [myId] [otherIP1] ([otherIP2] ...)
