Examples
- Implementation of elliptic curve digital signature arithmetic based on smart card
基于智能卡的椭圆曲线数字签名算法的实现 - The elliptic curve digital signature algorithm ( ecdsa ) is the elliptic curve analogue of the digital signature algorithm ( dsa ) . it was accepted in 1999 as an ansi standard , and was accepted in 2000 as ieee and nist standards . unlike the ordinary discrete logarithm problem and the integer factorization problem , no subexponential - time is known for the elliptic curve discrete logarithm problem . for this reason , the strength - per - key - bit is substantially greater in an algorithm that uses elliptic curves
椭圆曲线数字签名算法（ ecdsa ）是数字签名算法（ dsa ）的椭圆曲线对等。它先后成为ansi ， ieee ， nist和iso的标准，而且其它的一些组织正在考虑成为其标准。不象普通的离散对数问题和因数分解问题，椭圆曲线离散对数问题没有已知的亚指数算法，所以使用椭圆曲线的算法在密钥的位强度是足够高的。 - Hence , in this paper , we mainly study the digital multisignature scheme based on elliptic curve cryptography ( ecc ) . the existing elliptic curve digital signature algorithms do not realize secret partition and private key sharing , and do not fit for creating the digital multisignature . to solve this problem , we present an improved elliptic curve digital signature algorithm iecdsa for the digital multisignature
