RT @asanso: amazing stuff "Revisiting subgroup membership testing on pairing-friendly curves via the Tate pairing".

In 2023, Koshelev introduced an efficient method of subgroup membership testing for a list of non-pairing-friendly curves, using at most two small Tate pairings. In fact, this technique can also be...
