The MT-Pro Code is derived from the RtF Transciphering Framework. To start the code use the go file in examples/ckks_fv. The Code might be adjusted from ckks_fv/main.go.
When directly running - first adjust all the paths to your needs.

Below here the contents of the RTF Transciphering Framework README.md file are stated:
This is an implementation of the RtF transciphering framework along with the HERA cipher (proposed in Transciphering Framework for Approximate Homomorphic Encryption) and the Rubato cipher (proposed in Rubato: Noisy Ciphers for Approximate Homomorphic Encryption) using the lattigo library.
We implement the hybrid framework in ckks_fv, which contains the following functionalities.
- CKKS scheme (the same as ckks)
- FV scheme supporting multi-level operations (named as
mfv) - Halfboot operation
- Evaluation of the HERA cipher in the FV scheme
An example of finding modulus switching parameter in the RtF framework is given in examples/ckks_fv.
You can run the benchmark of RtF transciphering framework along with HERA or Rubato using RtF_bench_test.go. The benchmark parameters are given in rtf_params.go. To benchmark all the parameters, run the following command in ckks_fv directory.
go test -timeout=0s -bench=.
You can also benchmark specific parameter. For example, to run benchmark with HERA, run the following command.
go test -timeout=0s -bench=BenchmarkRtFHera
To run the HERA parameter 80as in the paper, run the following command.
go test -timeout=0s -bench=BenchmarkRtFHera80as
Benchmark with Rubato is also possible in similar way.
