Faster Final Exponentiation on the KSS18 Curve
Shiping Cai and Zhi Hu and Chang-An Zhao
Abstract
The final exponentiation affects the efficiency of pairing computations especially on pairing-friendly curves with high embedding degree. We propose an efficient method for computing the hard part of the final exponentiation on the KSS18 curve at 192-bit security level. Implementations indicate that the computation of the final exponentiation can be 8.74% faster than the previously fastest result.
