WebAbstract—Cryptographic pairings are important primitives for many advanced cryptosystems. Efficient computation of pairings requires the use of several layers of algorithms as well as optimizations in different algorithm and implementation levels. This makes implementing cryptographic pairings a difficult task particularly in hardware. WebDec 1, 2012 · Cryptographic pairings are based on elliptic curves over finite fields—in the case of BN curves a field \(\mathbb{F}_p\) of large prime order p. Efficient arithmetic in these fields is crucial ...
