| 摘 要： | 以椭圆曲线加密系统(ECC)为研究对象，系统地说明了椭圆曲线的数学原理和ECC工作原理，分析了ECC所具有的安全性高、密钥短等技术优势。针对数字签名算法对安全性和速度的技术要求，给出了将ECC应用到数字签名中的实现方法，即椭圆曲线数字签名算法(ECDSA)，ECDSA是具有短签名和短证书的快速签名算法。并以Java为鳊程工具实现了ECDSA。最后提到了ECC在移动通讯和智能卡方面的应用。

| Abstract: | This paper emphasis on the elliptic curve cryptography (ECC). The mathematics principle of elliptic curve and the principle of ECC are systematically explained. The conclusion that ECC is characterized by high security and small size is drawn. In order to gain high security and speed in digital signature algorithm, the application of ECC on digital signature is given. Elliptic curve digital signature algorithm (ECDSA) is a fast algorithm with small signature and certificate. The ECDSA implemented by Java is also introduced. At last the applications of ECC on wireless devices and smart cards are also mentioned. |
