摘要
安全TF卡是一款便于携带、支持公钥基础设施(PKI)的身份认证产品,它同时具有安全认证和存储的功能,在移动终端、手机银行、数字版权保护方面有着广泛的应用前景。文中提出了一种基于安全芯片的安全TF卡设计方法,简要介绍了TF卡的系统设计框架和程序开发流程,并针对Android平台,创新性地采用文件读写的方式完成上位机和TF主控制器之间的通信,通过优化通信协议大大提升了数据传输的速率和稳定性,最后介绍了利用JNI技术进行Android演示程序开发的要点。
Secure TF card, as a portable security product, could support public key infrastructure（PKI）. In combination of secure authentication and storage function, it has broad application prospects in many fields including mobile terminal, mobile bank and DRM. This paper proposes a design method for secure TF card based on a secure chip, and briefs the hardware framework and program design flow of the whole system. And then it is applied to the Android platform by innovatively using the method of read-and-write files to connect the mobile phone and the TF controller. This method enormously raises the transmission speed and stability of the TF card. Finally this paper gives the critical points in the design of Android Demo program by using JNI.
