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.
