WebAug 18, 2016 · Description. The TFHE library implements a very fast gate-by-gate bootstrapping, based on [CGGI16]. Namely, any binary gate is evaluated homomorphically in about 13 milliseconds on a single core which improves [DM15] by a factor 50, and the mux gate takes about 26 CPU-ms (or 13ms on 2 cores). The library implements a Ring … Web个人总结： 关于TFHE的话其实大概的思路就是优化了FHEW当中Refresh算法里面的ACC计算，把原来的 R G S W ⊠ R G S W → R G S W {\sf RGSW} \boxtimes {
