Hi Jimmy, ê is a bilinear map (a "pairing"), defined in line 87. (And I guess e is just a typo, it should be ê.)
Pairings are often helpful in constructing crypto scheme, because they add algebraic structure. The drawback is that you need special elliptic curves; "normal" curves don't offer pairing. See https://en.wikipedia.org/wiki/Pairing-based_cryptography for an introduction. Best, Tim On Thu, 2017-06-15 at 13:38 -0500, Jimmy Song wrote: > Hi, > > Please excuse my ignorance.
