智能卡安全技术研究

分别从4个不同的方面对智能卡的安全技术进行了研究。首先，从防范内部攻击和防范外部攻击2个方面对目前智能卡领域存在的潜在威胁及其相应防范措施进行了报告；其次，简要介绍了信息安全技术中的2种密码体制：对称密码体制和非对称密码体制及其相应算法；再次，从智能卡芯片安全技术和智能卡卡基安全技术2个侧面对硬件安全技术进行了研究；最后，从在智能卡领域具有典型应用的鉴别、数字签名和证书3个方面对软件安全技术进行了研究。

Study on the Security Technologies of the Smart Card

This paper discusses the security technologies of the smart card in four aspects.Firstly,it reviews some of the available techniques of attacking the smart card and corresponding secure methods through external attacks and internal attacks.Secondly,two types of encryption mechanisms:asymmetric key mechanism and symmetric key mechanism in IT security are introduced.Thirdly,it studies the security technologies in hardware secure form,which includes ICC and plastic support security technologies.At last,through three technologies: identification,digital signature and certification which are often used in smart card fields,it discusses the software secure feature of the smart card.
