where flag is the LSB of y. For the F2m curves I cannot make out how to do
188.8.131.52.2 appears to say flag is '1 if y of point > y of inverse point else
0' which I think just means `if y > x`.
15) by Julio Lopez and Ricardo Dahab appear to suggest my interpretation of
the IEEE method is off (I think).
<http://www.secg.org/sec1-v2.pdf%20section%202.3.3%20part%202.2.2> (which I
think is the standard reference) section 2.3.3 part 2.2.2 has yet another
notation that I do not understand.
I was told there are multiple ways. Can someone please explain the most
*standard* (or easiest) way requiring size m + 1, preferably from a
programmer's perspective? This math is beyond me :)
Any insight would be greatly appreciated.
