    • 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.
    • e和n是公共信息,d是私人信息。 基于e×d mod n的计算值生成电子签名。 签名生成装置100包括随机数生成单元103,第一计算单元111,第二计算单元112和签名生成单元121.随机数生成单元103生成随机数r。 第一计算单元111计算s1 = r×n。 第二计算单元112计算s2 = s1 + e。 签名生成部121计算s3 = s2×d mod n,并输出s3作为e×d mod n的计算值。 因此,签名生成装置100可以稳定地生成上述电子签名来抵抗差分电力攻击。
