| Abstract(in English) | In recent years, pairing encryption has attracted attention as an encryption method to realize high-performance encryption such as searchable encryption capable of searching keywords in encrypted state and broadcast type encryption capable of updating keys. The pairing map used for pairing cryptography performs mapping of two rational point groups $mathbb{G}_1$ and $mathbb{G}_2$ to a multiplicative group $mathbb{G}_{3}$ on an extension field which are computed by Miller's algorithm and final exponentiation. Therefore, in this research, this paper developed ELiPS (Efficient Library for Pairing Systems), a pairing library that adopts various speeding up methods, by using BLS curves that can realize high-speed pairing in pairing at 128-bit security level. As a result, the scalar multiplication on G1 and G2, exponentiation on G3, and optimal-ate pairing can be computed in 0.44[ms], 0.79[ms], 1.31[ms], and 3.91[ms], respectively. |
