Abstract

The use of public-key cryptosystems (PKC) received considerable attention. They are beneficial in encryption as well as signing which play an essential role in electronic banking and financial transactions. Elliptic Curve Cryptography (ECC) is one of best public key techniques because of its small key size and high security. Secure applications in smart cards present implementation challenges particular to the platform's memory, bandwidth, and computation constraints. ECC's unique properties make it especially well suited to smart card applications. ECC systems provide the highest strength per bit of any cryptosystem known today. The paper presents a new method for smart card implementation of elliptic curves, explaining how ECC can not only significantly reduce the cost, but also accelerate the deployment of smart cards in new applications. ECC permits reductions in key and certificate size that translate to smaller memory requirements (especially for EEPROM), which represent significant cost savings. This added functionality can play an effective role in electronic payment and online banking technologies.

智能卡上的椭圆曲线密码系统

公钥密码系统(PKC)的使用受到了相当大的关注。它们有利于加密和签名，在电子银行和金融交易中起着至关重要的作用。椭圆曲线加密(ECC)具有密钥大小小、安全性高等优点，是目前最好的公钥加密技术之一。智能卡中的安全应用程序对平台的内存、带宽和计算限制提出了具体的实现挑战。ECC的独特性能使其特别适合智能卡应用。ECC系统提供了目前已知的任何密码系统中最高的每比特强度。本文提出了一种椭圆曲线智能卡实现的新方法，说明了ECC不仅可以显著降低成本，而且可以加速智能卡在新应用中的部署。ECC允许减少密钥和证书的大小，这意味着更小的内存需求(特别是对于EEPROM)，这意味着显著的成本节约。这种新增的功能可以在电子支付和网上银行技术中发挥有效作用。
