| 摘 要： | 主要讨论在智能卡中实现ECC(EllipticCurveCryptography)算法的关键问题。ECC算法具有密钥长度短、安全性高、计算效率高等优点,但是ECC算法的实现本身面临着许多问题。同时考虑到智能卡相当于一台微型的计算机,它拥有自己的CPU、存储器和卡内操作系统COS(ChipOperationSystem)。但是在计算能力和存储空间有限的智能卡上实现ECC算法能否取得较好的效果。最后通过对多种实验基础的分析结果上提出了在非接触式智能卡上实现ECC算法的可用性。

| Abstract: | How to implement ECC algorithm in smart card is mainly discussed in this paper.ECC algorithm has some excellences like short key,high security and high efficiency,on the other hand it also faces many questions.At the same time,smart card corresponds to a micro processor having CPU,memorizer and COS.But actualizing ECC arithmetic in smart card which has finite computation ability and memorizer space also exists lots of questions to resolve.At last feasibility of How to implement ECC arithmetic in contactless smart card is given based on analysing lots of experiment results. |
