Abstract
PURPOSE:To attain the encipherment at a transmission information unit, and to realize an IC card having high security by adding an enciphered code for showing a method for the encipherment to a data transmitted by the transmission information, into the data transmission information. CONSTITUTION:An IC card 2 is connected or coupled electromagnetically to an IC card reader/writer 1 and a data is sent/received. A command train 3 and a response train 4 are constituted so that a start code 11 for showing the head is provided on its leading part, and subsequently, a command code or a response code 12, an enciphered code 13, a transmission data 14, and finally, an end code 15 are provided continuously. The enciphered code 13 is selected from the respective enciphered code tables stored in the IC card reader/writer 1 and the IC card 2, and in this enciphered code table 5, plural enciphered codes are stored.
