TFHE-CSPRNG
This crate contains a fast Cryptographically Secure Pseudorandom Number Generator, used in the TFHE-rs library, you can find it here in this repo.
The implementation is based on the AES blockcipher used in CTR mode, as described in the ISO/IEC 18033-4 standard.
Two implementations are available, an accelerated one on x86_64 CPUs with the aes
feature and the sse2
feature, and a pure software one that can be used on other platforms.
The crate also makes two seeders available, one needing the x86_64 feature rdseed
and another one based on the Unix random device /dev/random
the latter requires the user to provide a secret.
Running the benchmarks
To execute the benchmarks on an x86_64 platform:
RUSTFLAGS="-Ctarget-cpu=native" cargo bench --features=seeder_x86_64_rdseed,generator_x86_64_aesni
