ABSTRACT:
In a security system apparatus for a memory card used in an information processing apparatus, the memory card has an enciphering control data storing section which stores enciphering control data from which a predetermined password can be obtained by decoding, a main memory section, storing the data from the information processing apparatus, a comparison password storing section which stores a reference password, a password comparison section which compares the reference password with the password from the information processing apparatus, and an access control section for controlling access to main memory section. The information processing apparatus is provided with a data decoding section for decoding the enciphering control data. The information processing apparatus outputs the decoded password to the password comparison section and the access control section prohibits the access to the main memory section unless passwords coincide with each other as a result of the comparison by the password comparison section.
