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.
