Secure memory having anti-wire tapping

依据本发明的第一个方面，智能卡中不使用微处理器，而是利用密码术来对智能卡和智能卡读卡机进行鉴别，其中，密码术仅仅是提供一个预选的鉴别尝试号码，如果在访问智能卡之前没有复位，将会永远拒绝访问智能卡。依据本发明的第二方面，利用密码术或口令或两者单独访问智能卡的每一个存储区。 According to a first aspect of the present invention, cryptography without a dedicated microprocessor on the smart card is employed to provide authentication of both the smart card and the smart card reader, and wherein the cryptography provides only a preselected number of attempts at authentication, if not reset, before access to the smart card is denied permanently. According to a second aspect of the present invention, access to each the memory zones of the smart card may be individually provided by cryptography, passwords or both.
