WebThe MOV attack uses a bilinear pairing, which (roughly speaking) is a function e that maps two points in an elliptic curve E ( F q) to a element in the finite field F q k, where k is the embedding degree associated with the curve. The bilinearity means that e ( r P, s Q) = e ( P, Q) r s for points P, Q. Therefore, if you want to compute the ... WebDense univariate polynomials over. Z. /. n. Z. , implemented using NTL. #. This implementation is generally slower than the FLINT implementation in polynomial_zmod_flint, so we use FLINT by default when the modulus is small enough; but NTL does not require that n be int -sized, so we use it as default when n is too large for FLINT. Note that ...
