Twisted Edwards curve
open-in-new
<p>In <a href="/facts/Algebraic_geometry/rh7RHVp3">algebraic geometry</a>, the twisted Edwards curves are plane models of <a href="/facts/Elliptic_curve/60jvaHSA">elliptic curves</a>, a generalisation of <a href="/facts/Edwards_curve/zk5Vy1xl">Edwards curves</a> introduced by <a href="/facts/Daniel_J._Bernstein/KQLuMRTx">Bernstein</a>, Birkner, Joye, <a href="/facts/Tanja_Lange/8bYpR72r">Lange</a> and Peters in 2008. The curve set is named after mathematician <a href="/facts/Harold_Edwards_(mathematician)/JKfNgfJB">Harold M. Edwards</a>. Elliptic curves are important in <a href="/facts/Public_key_cryptography/gowoFTxS">public key cryptography</a> and twisted Edwards curves are at the heart of an electronic signature scheme called <a href="/facts/EdDSA/IbTRBhK3">EdDSA</a> that offers high performance while avoiding security problems that have surfaced in other digital signature schemes. </p>
