椭圆曲线密码学（Elliptic curve cryptography：ECC），一种建立公开密钥加密的演算法，基于椭圆曲线数学。利用有限域上椭圆曲线的点构成的 Abel 群离散对数难解性，实现加密、解密和数字签名。将椭圆曲线中的加法运算与离散对数中的模乘运算相对应，就可以建立基于椭圆曲线的对应密码体制。椭圆曲线在密码学中的使用是在 1985 年由 Neal Koblitz 和 Victor Miller 分别独立提出的。
注：计算与演算的区别，计算（包括的范围更大些，它可以是笔算、口算、估算等）；演算（是按照一定的原理、公式计算，有时在黑板上，有时在纸上，还可以在计算机上，演算注重的是最初的计算）。
由于 RSA、AES 等国际算法面临高强度算法禁售和被部署后门风险，我国基于 ECC 椭圆曲线，自研 SM2/SM3/SM4/SM9 一套安全算法。根据国家整体战略，金融及重要领域要逐步实现国密算法替换，另根据中国人民银行总体规划，在 2022 年金融行业要全面应用国密算法。在 FireFly 移动金融开发平台中，完善的提供了支持国密算法的加解密算法包。
优点：
椭圆曲线 ECC 算法基于椭圆曲线理论，可以用较少的计算能力提供更高的安全强度，有效地解决了“提高安全强度必须增加密钥长度”的工程实现问题，且已经得到广泛的支持和使用。因此，读者在选择加密算法时，ECC 算法不失为一个优秀的选择。
