SmartCard-2 Architecture(架构)

SmartCard架构分为以下三层：(传输层、服务层、应用层)
>The Transport Layer is the foundation for the Service Layer APIs. It provides general access to Secure Elements when an application is accessing it via the generic Transport API. The Transport Layer is using APDUs for accessing a Secure Element

>The Service Layer provides a more abstract interface to various functions on the Secure Element. They will be much easier to use by application developers than the generic transport API. One example could be an E-Mail application that uses a sign() function of the Crypto API and let the Crypto API do all the APDU exchange with the Secure Element (rather then handle all the needed APDUs directly in the E-Mail application).

>The Application Layer represents the various applications that make use of the Open Mobile API

 



体系结构可以被映射到不同的操作系统和根据操作系统可能看起来不同。api的描述是使用一个抽象级别,可以很容易地实现在不同的编程语言(例如,Java或c++)。
