Question regarding TFHE-rs library


i am a graduate student studying TFHE scheme.

After reading your TFHE-rs library tutorial, i found out that the execution time of single binary boolean gate is more than 10 times different between tfhe-rs library and openfhe library, and I wonder why. Is it due to a difference in the parameter?

Thank you!!

Hello @hyesungji,

We are focusing on TFHE scheme and constantly trying to improve performances while Openfhe has another approach by being multi-schemes.

To go more into the details, I would say part of the improvements are from using hardware acceleration (AVX2 instructions) and also having an optimized FFT (concrete-fft).

Hope it helps.
