Faster homomorphic encryption is not enough: improved heuristic for multiplicative depth minimization of Boolean circuits
somewhat homomorphic encryption multiplicative depth Boolean functions
2019/8/27
In somewhat homomorphic encryption schemes (e.g. B/FV, BGV) the size of ciphertexts and the execution performance of homomorphic operations depends heavily on the multiplicative depth. The multiplicat...
