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 ...
