Having Fun With BN-curves
A demonstration of key sharing BN-curves is here.
Elliptic curves are used fairly extensively in public key encryption (such as in Bitcoin and Tor). A BN-curve (Barreto-Naehrig curve) [paper] defines an elliptic curve which can be used for pairings that allow for a high security and efficiency level. This article uses pairings over a 256-bit BN curve and derives a…
