Abstract:
A method for using a smart card on an HPC, which method comprises the steps of:providing a smart card; providing a smart card reader for the insertion of the smart card; providing a smart card driver for configuring the communication method and initializing the communication interface, and providing the smart card an interface through the execution of the HPC CPU; executing the smart card driver via a manipulation program to implement the operations of data reading and writing; and identifying the user identity via an application program and performing data reception and transmission between the smart card and the HPC, wherein the step of data reception further comprises the steps of: initializing the smart card interface; starting to receive the data; ensuring that ORER and PER in the smart card interface register are 0; ensuring that RDRF of the interface register is 1; reading out received data from the SCRDR register and setting the flag RDRF in the SCSSR register as 0; ensuring that all the data are received; and setting the flag RE in the SCSCR register as 0.
