摘要
The decomposition unit (211) is represented by a polynomial r (x) = Φk (x) represented by a polynomial polynomial Φk (x) of degree d, a polynomial T (x), a polynomial h1 (x), and a polynomial h2 (x). It is represented by T (x)) / h2 (x), polynomial p (x) = h1 (x) r (x) + T (x), polynomial t (x) = T (x) + 1, and embedded degree k. For the final calculation part of the pairing operation on the elliptical curve, the exponential part is decomposed into an easy part and a hard part by the polynomial Φk (p (x)). The power calculation unit (22) sets the hard part as i = 0 ,. .. .. , D-1 for each integer i to the polynomial p (x) i-th power, λd-1 (x) = cd to the λd-1 (x) power, and i = 1,. .. .. , D-2 for each integer i using λi = T (x) λi + 1 (x) + ci + 1 to the λi power, h1 (x) power, h2 (x) power, multiplication, and inverse element calculation. To calculate.
