Represent field element in normal basis
Hi there
I'm having a normal basis, which is a basis of Fpn over Fp where (n=2) NB = [zeta, zeta*p] and a point P = E2.change_ring(Fpn).random_element() I would like to find a,b in Fp such that P = aNB[0] + b*NB[1]
Naive solutions result is memory overflow, and the Solve() function can't give me solutions with a,b in Fp. Any ideas?
To display blocks of code, either indent them with 4 spaces, or select the corresponding lines and click the "code" button (the icon with '101 010'). Can you edit your question to do that?
To display inline code, surround it within "backticks" or "backquotes" `.
