Miller Inversion is Easy for the Reduced Tate Pairing on Supersingular Curves of Embedding Degree Two and Three

Takakazu Satoh

Abstract

We present a simple algorithm for Miller inversion for the reduced Tate pairing on supersingular elliptic curve of trace zero defined over the finite fields with q elements. Our algorithm runs with O((log q)^3) bit operations.

Note: Major revision: our method is extended to the embedding degree three case. It turned out Akagi and Nogami[1] obtained similar results for some ordinary curves. The article is referred. Bug fix: Algorithm 4.1(2.1 in previous version), Step 6: check order of candidates of output to ensure correctness Fix several typos.
