Abstract
A dual usage smart card of CPU and logical encryption and its data synchronization method. Said method comprises that a CPU command processing module controls an accessing control module for the logical encryption storage region to read the data in the logical encryption storage region to a data format conversion module; said data format conversion module transmits the data to the CPU control storage region; the CPU command processing module controls the CPU control storage region again to transmit the data of CPU card to the accessing control module for the logical encryption storage region through the data format conversion module; and said accessing control module for the logical encryption storage region writes the data of CPU card into the logical encryption storage region.
