| abstract | An apparatus and method for realizing a safe and high speed operation in super elliptic cryptographic processing are realized. In the scalar multiplication of the factor D of the super-elliptic curve cryptography, the scalar multiplication is speeded up by performing an operation including 1/2 multiplication as the arithmetic processing. For example, a super elliptic curve having a parameter 2, a surface 2, h (x) = x 2 + x + h 0 , f 4 = 0, or h (x) = x 2 + h 1 x + h An operation including 1/2 multiplication in a scalar multiplication with respect to the factor D of a super elliptic curve having 0 , f 4 = 0 as a parameter, or a super elliptic curve having h (x) = x as a parameter is performed. Further, based on the [1/2 i D] calculated value for the fixed factor D, the application of a table that records which of k 1 , k 1 ', (k 0 , k 0 ') is correct, and also reduces the inverse operation This reduces the amount of calculation and speeds up the process. |
