摘要： e and n are public information and d is private information. An electronic signature is generated based on a calculated value of e×d mod n. A signature generation apparatus 100 includes a random number generation unit 103, a first calculation unit 111, a second calculation unit 112, and a signature generation unit 121. The random number generation unit 103 generates a random number r. The first calculation unit 111 calculates s1=r×n. The second calculation unit 112 calculates s2=s1+e. The signature generation unit 121 calculates s3=s2×d mod n and outputs s3 as the calculated value of e×d mod n. The signature generation apparatus 100 can thereby generate the above electronic signature securely against differential power attacks.

摘要： A scalar multiplication unit references a t-bit sequence representing a random number k one bit at a time from the most significant bit, and upon each referencing, sets in a work variable R[0] a value obtained by doubling a specific point G on an elliptic curve set in a scalar multiplication variable R, and sets in a work variable R[1] a value obtained by adding the specific point G to the work variable R[0]. The scalar multiplication unit 122 sets the work variable R[0] in the scalar multiplication variable R if the value of the referenced bit is 0, and sets the work variable R[1] in the scalar multiplication variable R if the value of the referenced bit is 1. A scalar multiple point output unit 123 outputs as a scalar multiple point kG a value obtained by subtracting a constant value 2tG from the scalar multiplication variable R.
