    摘要: An integrated circuit card includes a processing controller, a non-volatile memory having plural files in a hierarchical structure, with each file having an access conditions controller relating to the level number of said hierarchical structure, and a RAM having plural key information fields corresponding to the level numbers. Each access condition controller has an access key box designation table which indicates which keys should be verified and a vertical matching condition settings table which indicates which level keys should be collected for verification.
