ePrint Report: Pairing Optimizations for Isogeny-based Cryptosystems

Shiping Cai, Kaizhan Lin, Chang-An Zhao

In isogeny-based cryptography, bilinear pairings are regarded as a powerful tool in various applications, including key compression, public-key validation and torsion basis generation. However, in most isogeny-based protocols, the performance of pairing computations is unsatisfactory due to the high computational cost of the Miller function. Reducing the computational expense of the Miller function is crucial for enhancing the overall performance of pairing computations in isogeny-based cryptography.
