| titleOfInvention | Elliptic curve cryptographic operation apparatus, method, and program |
| abstract | An elliptic curve defined on GF (p m ), which is a m-th order extension field of a finite field GF (p) having a resistance to a simple power analysis method and high speed and p is a prime number of 2 or more. A calculation technique of scalar k multiplication k × P of base point P on E / GF (p m ) is provided. A scalar k multiplication k × P of a base point P is expanded by φ using a non-negative integer expansion coefficient, and the expansion expression is obtained by binary expansion of the non-negative integer expansion coefficient. Reference points P c (j) corresponding to the respective expressions P # c (j) are obtained by referring to the pre-calculation table. In each expression P # c (j) of the above expansion formula, when the obtained reference point Pc (j) or the reference point Pc (j) is the infinity point O, an elliptic curve E / GF ( Calculation is performed by substituting a point P ′ that is not an infinite point O on p m ).
