PAIRING COMPUTATION APPARATUS, PAIRING COMPUTATION METHOD, AND COMPUTER PROGRAM PRODUCT |
| 摘要 |
According to an embodiment, a pairing computation apparatus receives two points on a predetermined elliptic curve defined on a finite field, and outputs a pairing value that is an element on an extension field of the finite field. The apparatus includes a Miller function computation unit and a final exponentiation unit. The Miller function computation unit is configured to compute a Miller function based on a predetermined pairing method. The final exponentiation unit is configured to perform computation including raising the element on the extension field to the power of a value determined on the basis of a loop parameter of the Miller function. |
